WELCOME: Pat Neville, P.Eng., Vice President of Facilities for the Greater Toronto
Airports Authority, welcomed the committee to YYZ. Mike Riseborough, General
Manager Building and Facilities Maintenance, described the meeting logistics and dinner
arrangements.
APPROVAL OF MINUTES FROM CHICAGO MEETING: A motion was made by
Mike Shumack , seconded by Mike Riseborough, to accept the minutes of the June 2010
Chicago meeting. The motion carried.
IEC WORKING GROUP 45: In Sam Lott’s absence, Larry Smith summarized Sam’s
email stating that the working group has completed its work and IEC 62267 will
eventually be published. This issue is now considered closed.
RE-AFFIRMATION STATUS of ASCE 21: PARTS 1, 2, 3 and 4: Tedd Snyder
presented a schedule showing the re-affirmation status of all four parts of the Standard.
He stated that we have reached the five-year limit for the re-affirmation of Part 1, and
Page 1 of 23
that our goal is to merge all four parts into one volume and issue it within the next two to
three years. Tom McGean suggested that we could re-affirm Part 1 immediately, pro
forma, and then do it again with the combining of the four parts in the next two to three
years. Larry Smith stated that five years is the guideline maximum for re-affirmation. It
is not possible to hold a ballot at present because the Committee is out of balance, but we
can request an extension. Tedd Snyder stated that ANSI requirements can also provide
guidance.
NFPA UPDATE: Rod Falvey stated that the situation is essentially unchanged from that
reported at the Chicago meeting in June. He said that he would monitor requirements for
on-board fire suppression (described in the Chicago minutes) to see where this goes
within the NFPA committee. November 23, 2010 is the closing date for submission of
proposed revisions to the current (2010) edition of NFPA 130. All proposed revisions
will be subject to public comment.
EMI / EMC REQUIREMENTS: Rod Falvey reported that the IEC 62236 standard is
now available, and presented proposed revised wording for Section 2.1.8
“Electromagnetic Background” making reference to this standard instead of the
previously referenced MIL-STD-461E. The new wording (appended as Attachment 1)
requires an EMC control plan in accordance with APTA requirements in addition to
compliance with IEC 62236, because IEC 62236 does not include requirements for such a
plan.
MOTION: Moved by Dick Rhoton, seconded by Frank Culver, that the proposed
changes to the EMI/EMC requirements (appended as Attachment 1) be adopted. The
motion passed.
FRA REQUIREMENTS FOR SYSTEM SAFETY PROGRAM PLANS: As agreed
in the Chicago meeting, Diane Morse had obtained the FRA requirements for system
safety program plans (from Bill Hathaway) to compare them with the requirements in
Annex A of the APM Standard. (Annex A was based on MIL-STD-882, which is no
longer available). Diane compared all of the requirements in detail and found that,
without exception, each and every requirement in the FRA requirement exists either in
Annex A or elsewhere in the APM Standard. Her spreadsheet showing this will be
placed on the APM Standards Committee website by Mike Shumack or Pat Campbell.
The Chair thanked Diane for her excellent work in this regard.
Catherine Cronin expressed the concern that, because the FRA-equivalent SSPP
requirements are not in one place, but to some extent scattered throughout the APM
Standard, referencing these requirements is somewhat problematic. She believes it is
important that we can show clearly that the APM Standard SSPP requirements are
equivalent to FRA requirements.
The Chair stated that this could be clarified in a commentary with a preamble. The
commentary would include a statement that a complete SSPP must include all relevant
requirements of all parts of the APM Standard. He offered to provide information about
commentaries to Diane Morse for this purpose.
MOTION: Moved by Richard Prell, seconded by Frank Culver, that Diane Morse will
produce a commentary about the additional sections of the Standard that support the
Page 2 of 23
SSPP. Initially the commentary will reside only on the APM Standards website, but
eventually when the consolidated standard is published, the commentary will be attached.
Catherine Cronin will use the information in the commentary to determine whether a
footnote is required to be added to Annex A, or a statement included in Annex A, about
the inclusion of SSPP elements that are located elsewhere in the Standard.
The motion passed.
MEAN TIME BETWEEN HAZARDOUS EVENTS: Section 3.4 of the APM
Standard presently requires the aggregate MTBHE for all catastrophic and critical
hazards for the ATC system to be ≥ 108 hours. The interpretation of this requirement has
been questioned, as discussed at the Houston and Chicago meetings.
Tom McGean summarized recent correspondence on this topic among Committee
members. Extensive discussion followed. Tom suggested that some confusion has
resulted from the fact that Table 3-1 follows section 3.4, although it is referenced in
section 3.1.2.
MOTION: Moved by Tom McGean, seconded by Redjean Clerc, that we retain the
present section, make the last paragraph a separate section titled “ATC System MTBHE”
and add wording to the new section to emphasize and clarify that it applies not to the
entire system but only to the ATC system, and in addition applies only to non-CBTC
ATC systems not covered by the IEEE standard. Proposed new wording could be: “The
requirements in this paragraph apply only to the ATC system and only for non-CBTC
ATC systems. MTBHE requirements for CBTC ATC systems are as specified in IEEE
P1474.1-2004.” In addition, Table 3-1 shall be moved to be adjacent to Section 3.1.2.
Table 3-1 references shall not specify Section 3.4. These changes shall be balloted in
conjunction with the Parts 2 & 3 schedule. In the interim, Redjean Clerc & Tom McGean
will prepare a commentary.
The motion passed, although there were three dissenting votes, including Norm May and
Jim Fletcher.
ENVIRONMENTAL CONDITION LIMITS (SECTION 2.1): Chuck Elms presented
proposed changes to the requirements of this section, continuing the discussion from the
Houston and Chicago meetings. He reported that Dean Hurst had performed some
“scholarly work” on the issue of 50-year temperature and humidity extremes. Chuck also
presented revised wording regarding noise measurement, related to the amount of noise
energy the vehicle can emit in a free field. The revised wording for Section 2.1 is
appended as Attachment 2.
MOTION: Moved by Frank Culver, seconded by Tom McGean, that the proposed
changes to environmental condition limits requirements (appended as Attachment 2) be
adopted. The motion passed.
SYSTEM DEPENDABILITY DISCUSSION: Chuck Elms presented an example
system availability calculation for an example (fictitious) APM system based on the
method he had proposed in June in Chicago (refer to the Chicago minutes).
In the discussion that followed, Tom McGean stated that when the Standard was
originally produced, methods of calculating availability were “all over the map”, so the
Page 3 of 23
original intent was just to establish standard terminology. Catherine Cronin expressed
doubt that one method of calculation would work for all sites.
A report on this topic (“Performance Measurements of Automated Transit Systems at
Airports”) is presently being produced under contract to TRB by Lea+Elliott. Chuck
Elms suggested that he could discuss this with Chris Campbell at Lea+Elliott, distill its
conclusions, and present them at a subsequent meeting. The TRB report is scheduled to
be released “in the next few weeks”.
Suppliers were asked to comment on the topic of standardizing the method of calculating
system availability, and a range of opinions were expressed: Darin Friedman (MHI) said
he is in favor of a standardized approach because it would remove uncertainty and
increase uniformity. Redjean Clerc (Siemens) stated that he thinks each owner should
define his own availability criteria. Dean Hurst (Doppelmayr) suggested using the
approach defined by the TRB report. Dick Rhoton (Bombardier) stated that the proposed
standard approach is too complex, cumbersome and labor-intensive.
MOTION: Moved by Frank Culver, seconded by Doug Baird, that prior to the next
meeting, Committee members should obtain the TRB report “Performance Measurements
of Automated Transit Systems at Airports” and study it. Chuck Elms will clean up the
proposed method of calculation (plus the example calculation) as a Recommended
Practice and present it at a subsequent meeting. The motion passed.
LETTER FOR STATE PE LICENSING BOARDS: There was discussion regarding a
draft letter intended for the P.E. licensing boards of all the states to inform them that Part
4 has been issued. The discussion did not reach a conclusion, so it will be necessary to
take it up again at the February meeting in San Francisco. Suggested wording will be
distributed prior to the San Francisco meeting, to improve the chances of bringing this to
a conclusion.
QUALIFICATION OF INSPECTORS: As agreed at the Chicago meeting, Diane
Morse had considered how Annex D should be integrated with Section 16. She presented
“Proposed adjustments and configuration changes to accommodate Annex D into ASCE
21”. The resulting document, appended as Attachment 3, shows in strikethrough
paragraphs that have been made redundant, and in yellow highlight text that was balloted
in the Annex.
PRESENTATION RE THE THYSSEN-KRUPP TURBOWALK: Mike
Riseborough presented information on the ThyssenKrupp Turbowalk installation at
Toronto Pearson Airport Terminal 1. Two identical 260-metre long units are installed
there. Each unit has an acceleration section at one end, a deceleration section at the other
end, and the cruise section in between, which moves at 2 metres/second. These units
were installed in a cooperative development project with ThyssenKrupp. The original
delivery date was in 2007. They have been very popular with the travelling public.
Initially there were many little issues with material fatigue, premature wear, and
misalignment. The units have lots of optical sensors, which are somewhat sensitive to
dust and dirt. When the units go out of alignment they shut down to avoid “pile-up”.
The shut-down is implemented gradually so as not to “topple” people. Retrofits have
Page 4 of 23
been performed to correct these issues, and Mike stated that he is hoping that the latest
retrofit will be the last.
The availability target is 95% over 18 hours/day (549 hours/month), but the units have
never quite met this target. Conventional moving walkways are much more reliable,
achieving something like 99.96%.
The units are heavy and take a considerable amount of space below the floor, so the
building has to be designed to accommodate them. They are also quite noisy, but this is
not an issue because no one stays in the area where they are located. Energy
consumption is also relatively high, but the units have the capability to slow down when
no one is on them.
Friday, September 24th
THANKS TO GTAA: The Chair opened the meeting by thanking Mike Riseborough
and the other GTAA representatives for a very enjoyable outing on Thursday evening,
with an excellent dinner and first-rate entertainment.
FUTURE MEETING PLANS: Noting that the Toronto meeting will be a tough act to
follow, Paul Didrikson stated that a hotel has been selected for the February meeting in
San Francisco: The Villa Florence, located at 225 Powell Street, on Union Square. There
was some discussion about which week the meeting would be held, with the result that
the dates February 24th – 25th, 2011 were selected. The rate for the block of rooms that
will be held for those dates will be $139 per night, plus 15.65% tax.
Paul asked the members present regarding preferences for a tour, since the BART system,
MUNI, the cable car system and the SFO APM are all possibilities. Of these choices, the
cable car system and the SFO APM received the most votes from those expressing a
preference (BART: 4, MUNI: 3, Cable Cars: 9, SFO APM: 8).
The Spring 2011 meeting will be held in Paris in conjunction with the APM Conference,
which runs May 22nd to 26th. The APM Standards Committee meeting will probably not
take place at the conference facility for reasons of cost. Redjean Clerc indicated that
Siemens can provide a meeting room at their offices, which are located near the end of
Paris Metro Line 13, which runs from Montparnasse.
Possible tours could include the test track for NeoVAL, which is in Strasbourg, 2 hours
and 20 minutes from Paris by TGV; or the VAL system in Lille, which is about one hour
from Paris by TGV. There was also some discussion of a possible side trip to see the
PRT system at London Heathrow, which could be enroute to Paris for North American
participants.
Jonathan Esslinger reported that the APM Conference headquarters hotel will be the
Concorde, and the conference site is the Palais des Congrès de Paris. Additional
information regarding the APM conference can be found at www.apm2011.org.
Ortfried Friedreich suggested the possibility of holding the APM Standards meeting on
the Thursday & Friday before the APM conference, i.e. May 19th – 20th. By show of
hands the meeting participants who expressed a preference were almost evenly split on
this question (before: 7, after: 9).

APTA REPORT: Tom McGean presented the APTA report in the absence of Kevin
Dow. The report was on the topic of Positive Train Control, and the related RF spectrum
requirements. PTC is a ‘pet project” of the FRA. It uses GPS to define train locations,
but requires a back-up system because GPS can “black out”. This is mainly an issue for
main line railways and commuter rail, which are under the jurisdiction of the FRA.
Railroads have purchased spectrum for this purpose, but various transit authorities say
they can’t afford to buy spectrum and have asked APTA to do this for them. To this end
the FRA has sent a letter to the FCC supporting the transit authorities’ request to set aside
spectrum for commuter rail.
Dick Rhoton commented that the PTC requirement does not apply to all railroads. He
provided the following information post-meeting:
“Per FRA 2008-0132, i.e. The Rail Safety Improvement Act of 2008
PTC must be implemented by Dec 31, 2015 with the following criteria for applicable tracks:
1. All passenger carrying main line intercity and commuter lines, with limited exceptions.
2. All freight-only lines in Class I railroads carrying at least 5 million gross tons of freight
annually with "ANY" amount of poison or Toxic by Inhalation materials.
3. Somewhere (I can't find it) I remember the limit is > 25mil gross tons without toxic
materials and with certain speed limits.
Every applicable railroad was to file a plan of implementation with the FRA (due mid to late
spring this year) and FRA was to approve, reject etc. These are available on FRA
websites.
There was NO requirement in the FRA edict to govern "interoperability", but the Class I's
have internally agreed on interoperability.”
APM INJURY/ACCIDENT REPORT: Mike Riseborough presented a brief report
regarding an accident on the Miami Metromover system on June 20th. It involved a lowspeed (4.6 mph) collision which resulted in minor injuries to 18 people. The NTSB is
investigating. Dick Rhoton commented that a car lost collector shoes and thus became
non-detectable, and the back-up central tracking equipment failed to detect the car. The
system is not operated by Bombardier.
Mike suggested that he could use the assistance of persons with “control expertise” on the
accident task force. Dick Rhoton agreed to help.
PART 1 RE-AFFIRMATION STATUS: At the request of the Chair, Tedd Snyder
summarized the re-affirmation status of Part 1, Chapters 1- 5. Following some
discussion, the following motion was presented:
MOTION: Moved by Tom McGean, seconded by Dick Rhoton, that the Committee
should adopt a form similar to the one used by IEC for proposed changes to the Standard,
and require persons proposing changes to use the form. Pat Campbell agreed to obtain
the form and be the central point of control. The motion passed.
Note: The proposed form is appended as Attachment 4. The Chair stated that he will
send an e-mail to the membership regarding changes to Parts 2, 3, and 4 requiring any
proposed changes to be submitted by January 25th, 2011. This is in aid of the objective of
issuing a combined (Parts 1, 2, 3, and 4) with a target date at the end of 2011. Printing
would follow in 2012.

RESPONSE TO THE USE OF EVACUATION HANDLES BY PASSENGERS:
Redjean Clerc reminded the meeting that Yves Clarissou had raised a question regarding
the required response to use of evacuation handles by passengers at the Chicago meeting,
but the issue had not reached resolution. The Chair responded that this item will be added
to the agenda for the San Francisco meeting.
DOOR CLOSING FORCE DISCUSION: Victor Howe suggested that there is a need
to clarify in the Standard the fact that door safety edges need to be disabled when testing
to determine whether door closing force is within the specified limits. Discussion ensued
during which some members pointed out that in general the Standard does not specify
details of the method of testing its requirements.
Chuck Elms suggested that the Standard could be clarified with the addition of the words
“Independent of any recycling feature...” to the existing statement “Door closing forces
shall not exceed 133N (30 lb)…”.
This proposed change should be submitted using the new “Formal Comment Tracking
Matrix” (and in fact it is shown in Attachment 4, as provided post-meeting by Chuck
Elms and Pat Campbell).
MEMBERSHIP REPORT: The committee membership is unchanged since the
Chicago meeting and is out of balance, with:
(a) Consumer
25 members
40.3 % (0.3% over)
(b) Producer
20 members
32.3 %
(c) General Interest
17 members
27.4 %
All category must be between 20% and 40%. The Committee is presently not allowed
to hold a vote, because it is out of balance. Within the General Interest category, the subcategory of Regulatory members is required to be within the range of 5 to 15%. We are
presently at 4.8% with three regulatory members, therefore we need more regulatory
members if we wish to add to any other category of membership. Adding one regulatory
member would put the Committee back in balance, with 25 Consumer members equaling
39.7%. The Chair noted that the immediate priority is to find a qualified Regulatory
category member.
T&DI REPORT: Jonathan Esslinger presented his T&DI report, which is attached.
NEW BUSINESS: No new business was put forward.
ACKNOWLEDGEMENTS: The Chairman explained the procedure used in locating
meeting sites and stressed that our meetings are not funded by ASCE, but instead rely on
the generous support of members and their organizations. The Toronto meeting was
made possible with the commitment of a meeting room with AV support and tour by
GTAA, with continental breakfasts on both days, plus bus transportation to downtown
Toronto and the excellent dinner Thursday evening at Wayne Gretzky’s restaurant, and
the comedy show at Second City. Doppelmayr provided the Thursday lunch. GTAA
were overall host coordinators and also arranged the hotel room block.
Page 7 of 23
The Chairman specifically thanked Mike Riseborough, Ann Schwarts, Iori Moutine, Kent
Doering, and the other GTAA staff who had provided such excellent support for the
meeting.
ADJOURNMENT: Tom McGean made a motion to adjourn, seconded by Mike
Riseborough. The motion passed, and the meeting was adjourned at 12:00 pm.
Respectfully Submitted,
Paul Didrikson, P. Eng.

should provide for elimination of the influence of these conditions upon the equipment.
Compliance shall be in accordance with the requirements of IEC 62236 series of
standards, in particular;
 IEC 62236-1 Railway Applications -Electromagnetic Compatibility -Part 1:
General
 IEC 62236-2 Railway Applications - Electromagnetic Compatibility - Part 2:
Emission of the whole Railway System to the Outside World
 IEC 62236-3-1 Railway Applications - Electromagnetic Compatibility - Part 3-1:

An Electromagnetic Compatibility Control Plan/EMC Management Plan shall be
developed in accordance with “APTA SS-E-010-98 Standard for the Development of an
Electromagnetic Compatibility Plan".
Justification for Proposed Change
The current EMC requirements of MIL-STD-461E are general requirements for military
equipment and were not developed to specifically address the unique characteristics of
transit (including APMs). MIL-STD-461 includes requirements that cannot be
accomplished or, if actually undertaken would increase the costs without actually
improving its EMC characteristics in normal operating environment. IEC 62236 was
developed specifically for “Railways” and is applicable to APMs. IEC 62236 was based
on EN 50121 Railway Applications, Electromagnetic Compatibility, Emission and
Immunity of the Signaling and Telecommunications Apparatus, which has been invoked
previously for European transit installations.
MIL-STD-461E included the requirement for the generation of an EMC Control Plan.
IEC 62236 does not include this specific requirement and therefore the requirement to
generate an EMC Control Plan in accordance with APTA SS-E-010-98 is added as a
separate requirement.

CHAPTER 2
Operating Environment
There are two aspects to operating environment considerations. One deals with the
existing environmental conditions in which the system must operate (ambient) and the
other deals with the environment resulting from the existence and operation of the system
(induced). Both of these aspects are covered herein.
2.1 Ambient Conditions
The following sources of historical climatic data shall be considered when specifying
design climatic values: Source Number 1 is a basic compilation of low, high, and mean
values of temperature, humidity, steady and gusting winds, rainfall rates, and other
climatic characteristics as compiled by the National Oceanic & Atmospheric
Administration (NOAA). Source Number 2 summarizes the NOAA data in convenient
form. Source Number 3 provides temperature data and methods for calculating 50-year
return temperatures specified in Section 2.1.1.

Where the proposed site is located outside of the area of coverage of the above
documents, or within a microclimate, appropriate local weather data shall be used in lieu
of the above sources.
2.1.1 Temperature and Humidity. The system shall be designed to, and at a minimum,
be capable of continuous operation and serviceability in site ambient temperature
conditions that represent the 50-year return highest maximum and lowest minimum
extreme annual daily temperatures under naturally occurring combinations of temperature
and humidity See Chapter 14, Climatic Design Information, ASHRAE Handbook Fundamentals for the methods of calculating the 50-year return temperatures. Also, it is
not intended that the APM system should operate when the service area (eg., urban area
or major activity center) is closed because of any of these extreme conditions.
The temperature and relative humidity limit requirements for equipment shall reflect the
operating environment at the location in the system where it is installed.
Page 14 of 23
These environmental conditions are not intended for the design and operation of the
HVAC systems.
2.1.2 Wind. Maximum wind speeds shall be established for at least the following
conditions:
(1) Normal system operation
(2) Manual operation
(3) System survival
The maximum wind speed for normal system operation shall be used as the design wind
speed for safe automated system operation. If this wind speed is exceeded, automated
operation shall not be permitted or shall be appropriately degraded.
The maximum wind speed for manual system operation shall be used as the design wind
speed for safe manual operation. If this wind speed is exceeded, the system shall not be
permitted to operate.
The maximum wind speed for system survival shall be the design wind speed for all
structures. This wind speed shall be that used by local building codes.
2.1.3 Precipitation. If the system is intended for operation while subjected to rainfall,
snowfall, and icing, it shall be designed for operation at rates consistent with historical
data. Historical data are defined as the extreme conditions under which the area to be
served (eg., urban area or major activity center) would remain in operation and not be
closed. It is not intended to impose operational requirements more restrictive than what
the owner intends.
2.1.4 Lightning. Protection shall be provided against lightning incidence in the area for
those systems which are susceptible. Such protection should be in compliance with
Installation Requirements for Lightning Protection Systems, UL96A, 11th edition, 2001.
2.1.5 Existing Atmospheric Pollution. The system design shall tolerate atmospheric
pollutants which exist at the site. Such pollutants may include dust, dirt, salt, ozone,
smog, and other matter specific to the site. In the cases of dust and dirt, compliance shall
be with Environmental Test Methods and Engineering Guidelines, MIL-STD-810 F,
method 510.4.
2.1.6 Solar Heat Load. The design of systems which are subject to solar heating shall
be based on a peak, direct solar heat gain appropriate to the site. Material selection shall
minimize the deleterious effects of ultraviolet radiation.
2.1.7 Flood Zones. Flood levels shall be specified as the 100-year flood level. The
system shall be capable of surviving flooding with minimal damage to structure and
Page 15 of 23
equipment. Equipment and facility elements which can be damaged by flooding shall be
protected or installed above the flood plain elevation.
2.1.8 Electromagnetic Background. The system and all of its components shall be
electromagnetically compatible with the site environment at the initiation of system
operation. All system electrical and electronic equipment shall function satisfactorily in
the presence of electromagnetic emissions generated externally at the site. The
environment may include, but is not limited to: communications systems, microwave
facilities and transmissions, television and radio transmitters and repeaters, radar systems,
computer equipment and accessories, traffic control devices, magnetometers, electric
motors, controls, power tools, welders, x-ray equipment, power substations and
equipment, automotive vehicles, aircraft, and high voltage power lines.
The
electromagnetic environment particular to the site should be determined and the design
should provide for elimination of the influence of these conditions upon the equipment.
Compliance shall be in accordance with the requirements of IEC 62236 series of
standards, in particular;
 IEC 62236-1 Railway Applications -Electromagnetic Compatibility -Part 1:
General
 IEC 62236-2 Railway Applications - Electromagnetic Compatibility - Part 2:
Emission of the whole Railway System to the Outside World
 IEC 62236-3-1 Railway Applications - Electromagnetic Compatibility - Part 3-1:
Rolling stock - Train and Complete Vehicle
 IEC 6223-3-2 Railway Applications - Electromagnetic Compatibility - Part 3-2:
Rolling Stock-Apparatus
 IEC 62236-4 Railway Applications - Electromagnetic Compatibility - Part
4:Emission and Immunity of the Signaling and Telecommunications Apparatus
 IEC 62236-5 Railway Applications - Electromagnetic Compatibility - Part
5:Emission and Immunity of Fixed Power Supply Installations and Apparatus
An Electromagnetic Compatibility Control Plan/EMC Management Plan shall be
developed in accordance with “APTA SS-E-010-98 Standard for the Development of an
Electromagnetic Compatibility Plan".
2.2 Induced Environmental Parameters
The system shall be operated, stored, and maintained without imposing on the site any
condition which exceeds the limitations defined herein.
2.2.1 Exterior Airborne Noise. The following exterior noise levels emanating from the
system with all equipment operating normally should not be exceeded under the
conditions defined. Exterior noise levels shall be measured using at least a Type II
instrument, as defined in Specification for Sound Level Meters, ANSI Standard
S1.4-1983, and shall be set for fast or slow response as indicated.

Vehicle stopped on the guideway in a free field with all auxiliary onboard equipment in normal operating condition - at a point outside, 1.5m
(5 feet) from the doorway on a line aligned to the centerline of the
doorway and perpendicular to the plane of the doorway and 1.5m (5 feet)
above the doorway threshold: 74 dBA (slow response).
(2)
Under all normal operating conditions in a free field, 15m (50 feet) from
guideway centerline and from 1.5m (5 feet) above ground level to 1.5m
(5 feet) above guideway running surface: 76 dBA (fast response).
(3)
For the purposes of measurement the “free field” is approximated in tests
carried out in an open area away from any major obstructions or noise
reflectors.
Noticeable pure tones are not permitted. A pure tone is defined to exist when one 1/3octave band exceeds the arithmetic average of the two adjacent bands by 4 dBA or more
in the range of frequencies between 250 and 8,000 Hz. If an adjacent band contains a
pure tone, the next closest band without a pure tone shall be used in its place. A
noticeable pure tone shall be considered to exist when the 1/3-octave band containing the
pure tone contributes more than 1.0 dBA to the overall dBA level.
More stringent noise requirements may be necessary to satisfy local environmental
limitations.
2.2.2 Structure-Borne Noise/Vibration. System-induced vibrations shall be
imperceptible at or in surrounding buildings. The threshold of perception shall be as
defined by Guide to the Evaluation of Human Exposure to Vibration in Buildings, ANSI
Standard S3.29-1983.
2.2.3 Electromagnetic Radiation. The system shall be electromagnetically compatible
with its environment. The system shall not produce electromagnetic emissions, whether
conducted, radiated, or induced which interfere with normal operation of electromagnetic
devices or equipment used in and around the site at the initiation of system operation.
All system transmitting and receiving equipment, such as for ATC and audio and visual
communications, shall meet the licensing requirements of the Code of Federal
Regulations, Title 47, Chapter I, Part 90, Private Land Mobile Radio Services, Subparts S
and T; and the interference requirements defined in Title 47, Chapter I, Part 15, Radio
Frequency Devices.
