3.1.6
Statutory requirements are outside the scope of this standard. It is recognised that
compliance with the statutory requirements forms an important element of the product
assessment and railborne plant shall be declared compliant with the Machinery Directive
(as enacted by the Supply Of Machines (Safety) Regulations in GB). To claim presumption
of conformity to the machinery directive the manufacturer or supplier shall use the following
European Standard:
a)
On-track Machine – BS EN 14033-3:2009+A1:2011.

Engineering conformance is the subject of this standard and is explained more fully in
section 3.2 onwards. It is the assessment of the machine against the technical
requirements given in a specific nominated standard as shown:
a)
RIS-1530-PLT for the assessment of RRV, demountable machines, trailers and
associated equipment and trolleys.
b)
RIS-1702-PLT for the assessment of OTM in 'travelling' and 'working' modes.
Product Acceptance is the responsibility of each Infrastructure Manager (IM) who will have
their own standard to describe the process, it typically includes:
a)
Confirmation of the requirement for this type of plant.
b)
A check that an Engineering Conformance Certificate (ECC) for compliance to a
defined RIS exists.
c)
Safety justification and compatibility for potential for use on the infrastructure.
d)
The arrangements to ensure competent people and suitable facilities and
maintenance arrangements.
e)
Industrial relations agreement.
Use of Plant is responsibility of each user, to ensure safe use of plant and protect people,
infrastructure and railway operations, it typically comprises:
a)
Confirmation of ability to be used safely in this location.
b)
Confirmation that permitted use includes the job planned and capability of plant to
complete task.
c)
Confirmation of a valid ECC.
d)

G 3.1.7.1
G 3.1.7.2
It is advisable before commencing design and build of the first in class of any
item of plant to engage early with one or more infrastructure manager to
assess the likelihood of the plant being required. Enquiries concerning the
application of the formal product acceptance process requirements will
normally receive a written response for the first in class to state one of the
following:
a)
The plant or concept is not required by the infrastructure manager.
b)
Formal product acceptance request will not be required because plant
type already accepted.
c)
Formal product acceptance request will be required.
All subsequent plant of identical design and construction will assume product
acceptance by the original acceptance for the first in class.
3.1.8
Where the item of plant is confirmed as being suitable, and full formal product acceptance
request is not considered to be required, written notification to this effect will be given by
the infrastructure manager. The requirement not to have full formal product acceptance
does not mean that the plant does not need full Engineering Conformance Assessment set
out in this document and the relevant technical standards (see 3.2), all railborne plant shall
have Engineering Conformance Assessment and a formal Engineering Conformance
Certificate issued.
3.2
General requirement for engineering assessment process
3.2.1
Each item of railborne plant shall have an Engineering Conformance Certificate. It shall be
obtained from a Plant Assessment Body (PAB).
3.2.2
The plant Asset Manager or manufacturer shall provide evidence to the PAB,
demonstrating conformance of the design, construction and maintenance instructions of
the item of plant or engineering change with all relevant mandatory requirements of the
specific technical requirements document, as set out in 3.1.4.
3.2.3
If an item of plant does not comply with a requirement(s) of the nominated technical
standard set out in 3.1.4, the Asset Manager or manufacturer is permitted to seek a
deviation by writing to the infrastructure manager that mandates this document stating
which requirement(s) cannot be met, why it is impracticable to do so and the alternative
means by which performance is achieved. The Plant Standards Committee may be used to
discuss the application for general observation and comment. Details of any deviations
shall be forwarded to the PAB for it to consider during the engineering assessment
process. The PAB shall record details of deviations on the Engineering Conformance
Certificate.
3.3
Engineering Conformance Certificate
3.3.1
An Engineering Conformance Certificate confirms conformance of the design, construction
and maintenance plan with all relevant mandatory requirements of the nominated technical
requirements standard set out in 3.1.4. An Engineering Conformance Certificate shall be
required for a new item of railborne plant, or for any engineering change of a previously
accepted item of railborne plant in any area covered by the mandatory requirements of the
technical requirements standard set out in 3.1.4.

3.3.4
G 3.3.1.1
Note that the PAB assesses plant against the requirements of the technical
requirements standard only. The PAB process does not check the item of
plant against any statutory or legislative requirements. Issue of an
Engineering Conformance Certificate does not confer or imply that plant is
safe in all respects, nor that its performance meets the requirements of the
supply specification.
G 3.3.1.2
The manufacturer and / or supplier will need to perform a wider assessment
in order that foreseeable risks arising from the design, conversion and
intended operation, including foreseeable failure modes, and reasonably
foreseeable misuse, have been identified, assessed and mitigated at the
design stage. This will help the manufacturers and suppliers of OTP to meet
health and safety requirements. A legal framework is provided via the
Supply of Machinery (Safety) Regulations 2008 – as amended by the Supply
of Machinery (Safety) (Amendment) Regulations 2011.
For OTP, the initial Engineering Conformance Certificate shall be dated for a maximum life
of seven years, at which time it is permissible for the OTP to be re-accepted to the
applicable documents current at the time of re-certification.
G 3.3.2.1
When OTP receives an Engineering Conformance Certificate for the first
time, the certificate is given a life of up to seven years, starting from the date
of first assessment.
G 3.3.2.2
OTM and trolleys are permitted to be given an ECC without time limit. OTM
do not need to have time limit for their basic design which is based on more
onerous structural requirements and have a longer service life expectancy.
The standard OTM is based on a far longer design history.
Engineering Conformance Certificates issued as a result of re-assessment of the whole
item of OTP to current documents shall be dated for a maximum life of seven years from
the date of re-assessment.
G 3.3.3.1
When an item of OTP already has an Engineering Conformance Certificate
and is re-submitted for full assessment against the current version of this
document, then the Engineering Conformance Certificate that is issued as a
result of the assessment is normally given a life of seven years irrespective
of the age of any of the vehicle’s constituent parts.
G 3.3.3.2
In order for railborne plant to remain as certificated OTP after expiry of its
existing certificate, the whole railborne plant will need to be re-certificated to
the full requirements of the current version of RIS-1530-PLT at that time.
Where an OTP Asset Manager does not renew an expired Engineering Conformance
Certificate the OTP Asset Manager shall inform the Network Rail, Asset Information that
the railborne plant is no longer in use.
G 3.3.4.1
RSSB
Network Rail, Asset Information are informed because they are acting as the
national database for all railborne plant.

A new Engineering Conformance Certificate issued as a result of any modification to the
OTP shall have the same expiry date as the previously accepted OTP unless the whole
OTP has been re-assessed to the current document.
G 3.3.5.1
The OTP Asset Manager, when submitting an item of OTP for reassessment due to a modification during the life of an existing Engineering
Conformance Certificate, has a choice to make. They can:
a)
Have the whole OTP assessed against the current issue of RIS-1530PLT and have a new Engineering Conformance Certificate valid for
seven years.
Or
b)
3.3.6
Have only the modification assessed against the section of RIS -1530PLT applicable to the modification and receive a new Engineering
Conformance Certificate with the same expiry date as the original
certificate.
All OTP shall have the date of expiry of the current Engineering Conformance Certificate
displayed on the OTP. This shall be positioned next to the vehicle number stating 'ECC
expiry date dd/mm/yyyy'.
G 3.3.6.1
The Asset Manager should check that all their OTP have this label fitted. An
example of the label is shown in Figure 2. The material for the label should
be a self-adhesive label laminated with anti-graffiti surface. The information
should be black on a yellow background, in Helvetica medium font.

The PAB shall assess the railborne plant for compliance with the relevant technical
standard, see 3.1.4, and when satisfied that the railborne plant is compliant shall issue an
Engineering Conformance Certificate.
G 3.4.1.1.1
Engineering assessment consists of a review of the design and construction
of a railborne plant to check its compliance with the mandatory requirements
and a review of the maintenance plan for OTP to confirm that if followed it
would enable continued compliance throughout its operational life.

The certificate set out in Appendix A is an example of the required format for
OTMs, an example of the certificate for OTP and trolleys is given in
RIS-1530-PLT. However it is expected that the information shown should be
in the same order on the actual certificate produced and using the specified
wording shown in the examples as far as practicable (so that the necessary
information can easily be found and understood when required).
An Engineering Conformance Certificate shall be signed only by an authorised signatory
employed by the PAB with the appropriate scope of recognition.
The issue of all certificates shall be formally recorded by the PAB. Three copies of each
certificate that each carries an original signature and official stamp of the organisation (or
equivalent secure system) shall be issued and distributed, by the PAB, as follows:
3.4.1.3
a)
Railborne plant Asset Manager copy.
b)
PAB copy.
c)
Network Rail Asset Information.
G 3.4.1.2.1
A copy of the ECC is sent to Network Rail, irrespective which infrastructure
the plant is intended to be used on, because Network Rail have agreed to
host the national plant database. As a minimum this database holds only the
existence of the plant and the type, any other information supplied is at the
discretion of the infrastructure manager concerned.
G 3.4.1.2.2
OTM intended for use on Network Rail managed infrastructure in running
mode will additionally need to have conformance to engineering
requirements communicated to the Rolling Stock Library.
An Engineering Conformance Certificate shall be issued for either:
a)
An individual item of railborne plant.
Or
b)
A group of identical items of railborne plant. The Engineering Conformance
Certificate shall list the vehicle number of each railborne plant covered by the
certificate.

Requirements for assessment process
3.4.2.1
The assessment process, carried out by a PAB, shall include the following for the railborne
plant:
a)
An assessment of the first in class for all aspects of design, construction, testing and
condition of the railborne plant that could have an influence on its compliance with this
document.
b)
Where required to comply with the standards as set out in 3.1.4, testing of the
railborne plant under operational conditions in running, travelling and working modes
as necessary.
G 3.4.2.1.1
The first in class railborne plant is given a more rigorous assessment than
subsequent identical railborne plant. The first in class is assessed for all
aspects of its operation and construction in accordance with this document
against the relevant technical standard set out in 3.1.4.
G 3.4.2.1.2
All subsequent identical railborne plant need to be checked for conformity
against the first in class railborne plant and for the mandatory tests that
every new railborne plant requires. These tests are set out in the relevant
technical standard set out in 3.1.4. Further guidance is given throughout the
relevant technical standards for the different testing requirements between
the first in class railborne plant and subsequent railborne plant.
G 3.4.2.1.3
Identical railborne plant are those of exactly the same design. To be
identical the railborne plant must use the same manufacturer and model type
of all sub-components. The dimensions of major components must be the
same to within the tolerances on the engineering drawings. The wheel loads
of each wheel in tare and fully laden conditions should not vary by more than
5% between first in class and subsequent railborne plant for each wheel.
The tare weight of the whole railborne plant should not vary by more than
2%. Software version numbers of all control, braking and safety features
should be assessed to check the software core functionality is the same as
the approved / certified first in class railborne plant.
3.4.2.2
An assessment of the documented maintenance instructions for the railborne plant shall be
carried out to confirm that the requirements of the relevant technical standard set out in
3.1.4 are met.
3.4.2.3
The PAB shall issue an Engineering Conformance Certificate for the railborne plant when it
is satisfied that the railborne plant complies with all of the mandatory requirements of the
relevant technical standard set out in 3.1.4. The current issue number of the approved
maintenance plan shall be shown on the Engineering Conformance Certificate.
3.4.2.4

G 3.4.2.4.1
3.4.2.5
Revision of a maintenance plan does not necessitate reissue of the Engineering
Conformance Certificate provided that the railborne plant Asset Manager possesses a
letter from one of the bodies listed in 3.8.1.1, which verifies that the amendments to the
maintenance plan do not affect the railborne plant’s compliance with the relevant technical
standard set out in 3.1.4.
G 3.4.2.5.1
3.4.2.6
For subsequent identical railborne plant, the Engineering Conformance
Certificate does not require the design aspects to be reviewed separately for
each railborne plant, but recognises the first in class certificate and any
special limitations identified therein as evidence of conformance of those
aspects within its scope.
When the railborne plant(s) is subsequently re-certificated, if a revised
approved maintenance plan is in use, the reference on the new Engineering
Conformance Certificate should be updated.
For modifications, as described in section 3.8, where the same modification is being
applied across different types of railborne plant it is permissible to use the same process
described in 3.4.2.1 such that the first railborne plant modified has the design, construction
and testing and subsequent railborne plant are checked for conformance to the original
modification. The assessment and process used needs to be rigorous enough to identify
where there could be issues in transferring a modification to other machines and
consequently flag the need for further appropriate assessment. Where the Engineering
Conformance Certificate is issued for subsequent identical modifications the Engineering
Conformance Certificate for the first railborne plant modified shall be referenced in addition
to reference to the Engineering Conformance Certificate for the first in class railborne plant
if applicable.
G 3.4.2.6.1
For modifications to be considered the same they should consist of identical,
or very similar, modification instructions; and where connections are being
made to electrical, pneumatic or hydraulic circuits the same number of
connections of each type should be made across the fleet. The testing
regime following the modification should be identical, with the same pass or
fail requirements.
G 3.4.2.6.2
The Engineering Conformance Certificate should be clearly marked with the
certificate number of the first in class railborne plant (as set out in 3.4.2.4)
and also the certificate number for the first of type of the modification.
3.5
Limitations on the Engineering Conformance Certificate
3.5.1
Where the safe use of the railborne plant is assured only with limitations in place, then the
Engineering Conformance Certificate shall show the limitations within which the operation
of the railborne plant shall be restricted.
3.5.2
Appendix A shows an example of the required format of the Engineering Conformance
Certificate for an OTM and example certificates for OTP and trolleys are shown in
RIS_1530-PLT. The information, including any limitations, shall be in the same order on
the actual certificate produced and using the specified wording shown where possible (so
that the necessary information can easily be found and understood when required).
3.6
Requirements for Engineering Conformance Certificate
3.6.1
In addition to the requirements of 3.4 and 3.5, the Engineering Conformance Certificate
shall contain the following information:

3.7
Vehicle number for OTP and OTM
3.7.1
As part of the assessment process each OTP and OTM shall be given a unique identity
number. This number shall be allocated by Network Rail, and displayed on both sides of
the railborne plant. The number shall additionally be displayed on the data panels.
G 3.7.1.1
Network Rail, irrespective which infrastructure the OTP or OTM is intended
to be used on, have agreed to host the national plant database and hence
will allocate the unique vehicle number.
G 3.7.1.2
OTMs may already have a unique identity number from another member
state. This will always be used with the machine in running mode. Network
Rail (in conjunction with the infrastructure manager concerned if different)
will decide the use of the machine in travelling and working modes for
allocating the number.
3.7.2
The unique identity number on the railborne plant sides shall be readable from the ground
and at a distance of at least 5 m from the railborne plant. Where it is not practicable to
meet this requirement then the number shall be legible, as large as practicable and in a
prominent position.
3.7.3
Where it is not reasonably practicable to display the number on both sides of the railborne
plant, it is permissible to provide identification elsewhere on the railborne plant which shall
still be clearly visible as set out in 3.7.2.

3.7.4
The number may be provided on adhesive label or painted directly onto the
railborne plant. The number should be of a contrasting colour to the
background to which it is applied, to provide ease of visibility (a typical font
used is sans-serif).
Data panels shall be attached to each side of the railborne plant following full assessment
of the railborne plant to the relevant technical standard set out in 3.1.4. The data on each
panel shall be legible at a distance of 2 m from the side of the railborne plant.
G 3.7.4.1
The data panels, (details set out in the relevant technical standards), can be
reformatted where there are constraints on the railborne plant size, the entire
data panel needs to be visible simultaneously.
3.8
Modifications
3.8.1
Modifications to all railborne plant
3.8.1.1
Except as set out in 3.8.2, modifications to previously accepted railborne plant shall be
re-certificated by a PAB or assessed by a competent engineer that re-certification is not
necessary. A competent engineer is one of:
a)
An accredited signatory of a PAB.
b)
A professional head of rail vehicle engineering of a railway undertaking operating
on-track machines.
c)
Network Rail, Professional Head of Plant Engineering.
d)
London Underground, Relevant Head of Technical Discipline.
G 3.8.1.1.1
A modification is anything affecting compliance with the relevant technical
standard set out in 3.1.4, including the maintenance requirements. Normally
a modification will require skilled intervention and is not already described in
the instruction handbook.
G 3.8.1.1.2
For OTP, in the majority of cases the Asset Manager of the railborne plant is
not the holder of a safety management system, therefore it is recommended
that advice be sought from the PAB or the relevant professional head as
shown in 3.8.1.1.
G 3.8.1.1.3
The decision whether a modification requires re-certification is based on
whether the change is significant.
3.8.1.2
The decision that formal re-certification is not required shall be documented and signed by
the competent engineer who made the decision. The railborne plant Asset Manager shall
keep a copy of this written confirmation on file and retain an auditable record of all work
undertaken and approved.
3.8.1.3
The PAB shall assess any modification and consider whether any limitations need to be
added to, amended or removed from the Engineering Conformance Certificate to achieve
compliance with the relevant technical standard set out in 3.1.4.
G 3.8.1.3.1
RSSB
This clause is applicable when any Engineering Conformance Certificate is
re-issued, for example for a change of Asset Manager or change of
identification number.

3.8.1.4
For OTP, the Asset Manager shall provide to all Infrastructure Managers who are known to
have granted Product Acceptance the item of OTP, details of all modifications undertaken
to a railborne plant, including details of work undertaken, and a copy of either, the
competent engineer’s assessment, or a new Engineering Conformance Certificate that has
been issued.
3.8.2
Modifications to mobile elevating work platforms
3.8.2.1
The railborne plant Asset Manager shall have any modification to a mobile elevating work
platform (MEWP) assessed by a PAB, manufacturer or a Notified Body (NoBo), for the
potential to affect the compliance with BS EN 280:2001 or later.
3.8.2.2
Where the modification will affect the compliance with BS EN 280:2001 or later, an
assessment shall be made and where compliant, a certificate of conformance to BS EN
280:2001 or later, shall be issued covering the modification.
G 3.8.2.2.1
The requirements of 3.8.2.1 and 3.8.2.2 are that all modifications to railborne
plant that include MEWP functionality are assessed by a PAB, manufacturer
or NoBo. The professional head of rail vehicle engineering of a railway
undertaking does not have the discretion as to whether or not a modification
requires re-assessment for compliance to BS EN 280:2001.
G 3.8.2.2.2
Following the decision about compliance with BS EN 280:2001 the next
decision is about compliance to the relevant technical standard set out in
3.1.4, as set out in 3.8.1.1.
G 3.8.2.2.3
The assessment of compliance to BS EN 280 is carried out by a NoBo (as
stated in Machinery Directive).
3.9
Innovative solutions
3.9.1
Any innovation proposed for plant or its component parts, where the innovative solution is
not covered, or not adequately covered, by the relevant technical standard set out in 3.1.4
shall be assessed by a PAB for its suitability against a comparable national or international
standard recognised by the European Union. The standard(s) against which the innovation
is assessed shall be shown on the Engineering Conformance Certificate.
3.9.2
Where innovative features on plant are not covered by the requirements of the relevant
technical standard set out in 3.1.4s, the PAB’s assessment shall be for compliance with an
appropriate UK or EU standard. If there is no appropriate standard, the Asset Manager
shall convene an expert group including the manufacturer, an infrastructure manager,
RSSB and a PAB to determine if the innovation is acceptable.
G 3.9.2.1
All railborne plant, or major components / modules for railborne plant that
have not previously been assessed should be assessed for compliance with
the relevant technical standard set out in 3.1.4 and an Engineering
Conformance Certificate issued. Any new railborne plant, or more likely a
system or component for a railborne plant, which is not currently covered by
the relevant technical standard, should be assessed for railway safety and
its effect on other railborne plant and the infrastructure.
G 3.9.2.2
Components for a railborne plant are those that are significant in their effect
and are a fundamental change from those components previously assessed.
For example a different style of wiper blade for a windscreen wiper does not
come into this category, but a new proposed rotary centrifugal screen is
covered by this clause.
