Date Issued: April 24, 2003File: 02-2792

Question: In meeting the requirements of UG-79 of Section VIII, Division 1 and AF-111 of Section VIII,

Division 2, is the use of heat or flame permitted to correct the shape of pressure parts, provided the use of

these techniques does not impair the physical properties of the material?

Reply: Yes.

Note: This interpretation was inadvertently omitted from Vol. 53 of the interpretations. It also appears as

VIII-1-01-157.


Subject: Section VIII, Division 2 (2001 Edition, 2002 Addenda), AM-211, Fig. AM-211

Question: Is it the intent to allow the rounding to the nearest whole number of the average value of the

three impact test specimens as required by UG-84(c) and Fig. UG-84.1?

Reply: Yes.

Note: This interpretation was inadvertently omitted from Vol. 56 of the interpretations.


Subject: Section VIII, Divisions 1 and 2 (2004 Edition, 2006 Addenda), AG-121

Subject: Section VIII, Division 2 (2004 Edition, 2006 Addenda), AD-160

Date Issued: June 21, 2007File: 07-1016

Question: If the expected range of operating pressure variations does not exceed 20% of the design pressure

when using AD-160.2 and 15% of the design pressure when using AD-160.3, may these pressure cycles be

neglected when evaluating the exemption from fatigue analysis even though the number of cycles may be

much greater than 106?

Reply: Yes.
