About NDT perssonel & procedures
(OP)
Dear Sirs,
I work for a company that produces tanks, vessels, structures, etc. Our client have contracted a third companie for the Quality Control of theirs products.The supervisor say that all NDT procedures (VT, PT, RT or UT) must be signed by a Level III Inspector, he say that it is a requirement for the Practice SNT-TC-1A of ASNT.
We execute VT and PT with our personnel (qualified as Level II according to RP SNT-TC-1A of ASNT) and, RT and UT with a NDT inspection subcontractor (subcontractor personnel qualified according to RP SNT-TC-1A of ASNT)
I have reviewed some of the common standards that we used in our projects,such as API 650, ASME Section XIII Div. 1 (BPV Code), AWS D1.1, etc., and these standards are references for the recomended practice, qualification and certification of the NDT Personnel by SNT-TC-1A.
Also for the NDT procedures, the referenced standard is ASME Section V (BPV Code), I reviewed this standard and each article give criteria to consider for NDT procedures, but I don't see any reference to sign off these documents by a Level III.
I will be thankful of your comments.

If you have no Level III retained, then you have no certified Level II's. It takes a L/III to certify and 'supervise' all L/II's. If your L/II's only received training, and you did not retain a L/III, they are not considered as being certified under SNT-TC-1a. Your folks are 'qualified' but non-certified.

So what does your written practice say?
RE: About NDT perssonel & procedures
A Level III must be involved in the certification process as defined in 5.4 and 8.0 of SNT-TC-1A.

SNT-TC-1A requires that the "Written Practice" (procedure) only to be signed by the employer's designated Level III, who may or may not be directly employed by the Employer. It does not define that the Employer's NDE method procedures be signed by a Level III.
