Non-destructive testing qualifications within the quality assurance system
Thread Content
Dear friends: In the manufacturing of A2-class pressure vessels, if non-destructive testing is outsourced, the person responsible for such testing must have Level II qualifications in RT and UT. Is it also required to have qualifications in PTH and MT?
It is necessary; the person responsible for non-destructive testing must sign to confirm the outsourced non-destructive testing report. If they lack the appropriate qualifications, how can it be determined whether the report meets the requirements?
Thank you, I think the same way, but I don’t know where it comes from Disagreements among colleagues
For outsourcing, only a responsible person is required, and this person must meet the criteria of having RTUT scores in the appropriate range and at least 4 years of experience; there is no additional requirement regarding MTPT
Page 32 of T SG07-2019, the Safety Technical Specifications for Special Equipment, specifies clearly that requirements apply only to UT and RT, with no requirements for the others.
This is a serious bug. Under normal rules, outsourcing is not allowed for regular units. Situations where outsourcing is necessary include: first, when it’s truly impossible to handle the task on site. The person responsible for quality control in such cases must possess the appropriate qualifications and be accountable for ensuring the quality of inspections； Secondly, if the necessary qualifications are indeed lacking, then the externally assigned quality responsible person is accountable for the quality of the inspections. The externally assigned quality supervisor is responsible for evaluating the inspection quality carried out by the entrusted party; without a certificate, such a person is likely to lack the necessary capabilities, and thus unable to evaluate the quality of their inspections. However, the regulations do not explicitly state that a certificate is mandatory.
No requirements for PT or MT qualifications
