Interpretation: IX-07-08
Subject: QW-200.2(c), Changes to PQR (2007 Edition)
Date Issued: February 12, 2008
File No: 08-209
Question (1): Can additional tests and data that are not required by Section IX (i.e., hardness
ferrite, corrosion, etc.) be added to a PQR at a later date when the testing was not performed as
part of the original PQR, but followed the conditions of the original qualification?
Reply (1): Yes.
Question (2): If the tests and data noted in Question 1 are added to the PQR, would
recertification, including date, be required?
Reply (2): Yes. All changes to a PQR require recertification (including date) by the
manufacturer or contractor per QW-200.2(c).

Hi,--
Method is not a matter,
The values are important,
if ur old values satisfy with new requirement then no need go for A new PQR.
