Question

Use of SNT-TC-1A is mandatory when:

Answer 1

The use of SNT-TC-1A is mandatory when a company has included it in their internal written practices or when it is required by contractual obligations, governmental, or industry-specific regulations for NDT personnel certification.

Step-by-step explanation:

The use of SNT-TC-1A is mandatory when a company or organization has adopted it as a part of their written practice for the qualification and certification of non-destructive testing (NDT) personnel. SNT-TC-1A is a standard that provides guidelines for employers to establish their own NDT certification programs. While the SNT-TC-1A is considered an industry standard, it is not a law; therefore, its use is usually mandated internally within a company or when specified in contracts, codes, or regulations requiring compliance with SNT-TC-1A.

Examples of when the use of SNT-TC-1A may be mandatory include:

• When a contract between two parties stipulates that the qualification of NDT personnel must adhere to SNT-TC-1A.
• When government or industry regulations cite SNT-TC-1A as a requirement for NDT operations.
• When a company's internal policies specify that SNT-TC-1A should be followed for the qualification and certification of their NDT technicians.

Importantly, if an organization decides to follow the ASNT recommended practice outlined in SNT-TC-1A, they are required to comply with its guidelines, making its use essential within that context.
