PG-20
•
•
National
Board
Training
Revised PG-20 to include cold forming
rules for carbon and carbon-molybdenum
materials. Added reference to PG-20-1.2
in pg-90.1.12.
An effort was undertaken to collect the
latest corrective actions employed by the
various US boiler manufacturers that
encompasses the range of fabrication
and design conditions where failures had
occurred, and develop a set of rules that
incorporates the necessary controls.

PG-27.2.3 deletion
•
•
•
National

Training
Remove the reference to PG-27.2.3 in
PG-27.1 and delete paragraph PG27.2.3.
The deletion of paragraph PG-27.2.3
removes the 705.4°F temperature
check for thick walled cylinders.
Per PG-27.1, already permits the use of
the A-317 equations without restriction
on wall thickness or temperature.
15-1786
5
PG-60.1
National
Board
Training
Revise PG-60.1 to clarify that the level gage shall
cover the full operating range.
The following benefits will result from this action.
1.
The Code will clarify the minimum range for a water
gage glass, which is already a general practice by the
manufacturers. However, it is not presently defined.
2.
A water gage glass that covers the full operating
range enables an operator to validate the operating
level that is indicated by other indirect (remote) level
indicating device. This is especially helpful if a
discrepancy ever occurs between two or more remote
level indicators.
3.
Eliminate the risk caused by short range water level
gage glasses from being installed, which may prevent
the operator from actually confirming high & low
alarms or low water shut down levels.
4.
This clarification will provide a defined resource for
specifiers and improve operating safety.

Line 5 of Form P-4A and Form P-4B, has the
provision “Code Design By :” which allows an
organization other than the Certificate Holder
/ Manufacturer (who certifies Form P-4A
and/or Form P-4B) to perform the design
work. Interpretation I-98-17 further clarifies
that design may be performed by a noncertificate holder.
This created confusion about who ultimately
bares the responsibility for design especially
when the Certificate Holder receives an order
to “build to print” and often not provided
with the supporting design calculations.
PG-112.2.5 was revised to state that the
organization certifying Form P-4A or P-4B
retains the responsibility for the Code design.

Surface Blowdown
A surface blowdown is normally a surface blow, and is

Solids concentrated in boiler water
tend to promote foaming and scaling
with a resultant loss of heat transfer
which may result in overheating of the
boiler tubes. Solids also may settle to
the bottom of the boiler to form
sludge. “Blowing off” part of the boiler
water is a means of removing solids
from the water while controlling boiler

VIII-1
92
Paragraph U-2(g) and New Appendix 46
•
•
National
Board
Training
Paragraph U-2(g) revised with rules
to allow usage of ASME Section
VIII, Div. 2 for design methods not
provided in Section VIII, Div. 1 as
well as other recognized Standards
or Codes.
New Appendix 46 was created to
incorporate Code Case 2695 into
Section VIII, Div. 1 and provide a
means for the designer to use the
rules given in ASME Section VIII,
Div. 2.
12-307
93
Revised Figure UW-3
•
•
National
Board
Training
Revised Figure UW-3 by adding a
sketch of weld neck flange with its
weld category as C.
The sketch now shows a weld
neck flange pointing out it is as
category C as opposed to category
B. Note that this weld has been
category C for a long time.

95
Revised Paragraph 10-13(b)(8)
•
•
National
Board
Training
Revised Paragraph 10-13(b)(8)
The Code record should be identified as the Interpretation Report. The interpretation
of radiograph indicates that the weld or component complied with all of the applicable
Code rules at the time of fabrication/manufacturer and documented accordingly.
In addition, surface examinations such as dye penetrant and magnetic particle
examination must also be retained.
17-1378
96
USC-66(c)
•
National
Board
Training
Revised subparagraph UCS-66(c);
added new subparagraph (c) to Note
1, and revised the text for Note 2(a)
in Figs. UCS-66/66M
1. Assign "as forged" A/SA-105 forged
flanges to Curve A for toughness
considerations, and
2. Impose a limit of 0F (-18C) upon
MDMT for the exemption of "as
forged" A/SA-105 forged flanges
from impact testing under the rules
of UCS-66(g), which is consistent
with the current requirements of
Section VIII, Division 2.

UG-116 Nameplates
•
National
Board
Training
Nameplate markings between Divs. 1 and
2 have been aligned by reducing the
“construction type” markings that are
mandatory on the nameplate for Section
VIII.
1) Removed the W, P, B and RES from the table
titled "Types of Construction" in UG-116(b)
2) Added the UHT marking to UG-116(b) and
reference to UHT-115
3) Added the WL marking to UG-116(b) and
reference to ULW-115
4) Added the ULT marking to UG-116(b) and
reference to ULT-115
5) Added a reference to UIG-116 with the
Graphite marking G
6) Added the CS marking to UG-116(b) and
reference to Mandatory Appendix 44, 44-7
15-317

removed are the W and the F. See 13-63, and
also was under RN 13-2006
98
Definition of "NPS" in Appendix 3
•
•
Added definition of "NPS" in
Appendix 3
There are a number of other
places where the Code limit a size
to a NPS value. It has not been
explicitly defined when the Code
states the size is limited to a given
NPS size. If one is using a
standard fitting, it may be defined,
but it may not well defined for a
custom engineered component.
National
Board
Training
“NP S : Nominal Pipe Size as
used throughout this Division
is defined as the pipe outside
diameter for a given pipe size
in accordance with ASME
B36.10M”

Since martensitic stainless
steels are particularly crack
sensitive, paragraph
UHA-34 was revised to add

Training
Deleted Appendix DD
Certification and Accreditation requirements
are now contained and kept current at CA
Connect, including preparation, application,
and certification guidelines. This eliminates
the need to maintain this information in
nonmandatory appendixes and normative
annex. This item will eliminate guides for
certificates of authorization in VIII-1 Appendix
DD, VIII-2 Annex 2-H, VIII-3 Appendix 3 and
eliminate supporting references. Reference to

Revised UW-11(a)(4) to remove the second reference to Paragraph (2).
This proposed change makes nozzle or communicating chamber radiography required only when
the nozzle or communicating chamber itself exceeds the thickness requirements of UW-11(a)(2),
or if the shell and/or head (so the entire vessel) is designed for lethal service or as an unfired
steam boiler exceeding 50PSI.
UW-11(a)(4) does allow for certain exemptions for Category B and C butt joints, due to thickness
in these nozzles and communicating chambers, but not for Category A or D joints butt joints

UW-50
•
•
National
Board
Training
Incorporated the provisions of
Code Case 1518-5 into UW-50.
The incorporation of this code
case will permit waiving the

qualifying conditions have been
met.

to use UT in lieu of RT applies to welds in which the
thinner of the members joined is 1/4 inch thick or
greater.
•
Revised UW-51(b) to simplify the wording, and
delete the requirement for Inspector confirmation of
the defect indication by ultrasonic examination.

New Article KM-6
•
•
Created new Article KM-6 in Div. 3,
to consolidate location of all
material models used for analysis.
Created Part KM-6, moved KD-360
cyclic stress strain curves to Part
KM-6, modified reference to
material model in KD-231.1, moved
KD-231.4 to new Part KM-6,
modified material reference in KD234.1, KD-236 and other misc.
references throughout the book to
refer to new part KM-6, and moved
description of elastic perfectly
plastic material model to KM-6 from
KD-236.

KM-211.1(b) and KM-211.1(c)
•
•
National
Board
Training
Revised KM-211.1(b) and KM211.1(c) to specify a test specimen
depth location of T/2 instead of
T/4.
T/4 did not adequately capture the
potential variation in mechanical
properties through the thickness of
the plate, especially for the thicker
plates which will be allowed by the
proposed changes in RN 13-1999.
It is recognized that the most
variation in material properties of a
plate will occur at the mid-point of
the thickness (T/2).
