Subject: RE: [MW:3731] NDT procedure qualification
Date: Wed, 25 Nov 2009 16:48:14 +0530
If you refer ASME V clause T522.1,T721.2 & T621.2 for UT,MT & PT respectively then you will find that when procedure qualification is specified by the referncing code section(i.e construction code...ASME VIII, 31.3 etc) , change of requirment in relevant table ( ASME V )identifed as an essential variable shall require requlification of written procedure by demonstration.
Where as per ASME V clause T 221.2 for RT - Only demonstration of density & image quality requirements as per written procedure on production or technique radiograph shall be considered satisfactory evidence of compliance of that procedure.
Suppose if you are qualifying welder by radiography then even written procedure is also not required as per QW 190 Only demonstration of density & image quality requirements on production or technique radiograph shall be considered satisfactory evidence of compliance with article 2 of section V.
I think its more clear now. If you come across with some clients specification then you may have to demonstrate the NDT procedures beside abovsaid code requiremnts.

Good Morning ,
Basically NDT procedures are drafted in line with specific codes for example ASME Sec V which is universally adopted. If client insist or raise any doubt than only we have to demonstrate

Is it mandatory to demonstrate NDT procedure qualification before applying in the actual job? If so, please give the code/standard reference.
