What is an ASME stamp audit

An ASME stamp authorizes manufacturers to design and stamp pressure equipment per ASME BPVC. To maintain that authorization, the company undergoes a triennial audit by an Authorized Inspector (AI), who verifies that the quality system remains compliant — including the entire NDE program.

FREQUENTLY ASKED QUESTIONS
How often does the ASME stamp need to be renewed?+
Every 3 years. The process involves an Authorized Inspector audit verifying that the quality system, procedures, and personnel qualification remain compliant with ASME BPVC.
What happens if the company fails the audit?+
The company receives a deadline to correct nonconformities. If unresolved, the stamp may be suspended or revoked, losing the authorization to stamp equipment. Restarting the certification process can take months and represent significant contract losses.
Can SimpleNDT act as external Level III for an ASME stamp?+
Yes. SNT-TC-1A allows the use of an external Level III provided it is documented in the company's Written Practice. Dan Yamashita is ASNT Level III certified and acts as consultant for multiple ASME stamp holders.
