American Society of Nondestructive Testing (ASNT)

IHS Markit is your source for ASNT standards and publications.

The American Society for Nondestructive Testing (ASNT) is a technical society for nondestructive testing (NDT) professionals. ASNT evolved from The American Industrial Radium and X-Ray Society which was founded in 1941.

ASNT's publications are designed to exclusively serve the nondestructive testing industry. NDT technicians in the field, researchers, manufacturers and ASNT members around the world can rely on ASNT publications for up-to- date information about NDT technology and the latest developments at ASNT.

ASNT publishes and maintains an important standard, SNT-TC-1A, which, with the addition of Codes of Practice ANSI/ASNT CP-189 and ANSI/ASNT CP-105, covers all aspects of qualification and certification of NDT personnel. SNT-TC-1A specifies an employer based certification scheme for Level I and Level II NDT personnel, which is extensively used in countries not enforcing EN 473 (European Union).
