The American Society for Nondestructive Testing, Inc. or 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.[1] Its headquarters is located in Columbus, OH, and there are 70 local sections in the United States and 14 local sections in other countries.

The organization[edit]

ASNT is a nonprofit organization, which is governed by the Board of Directors and the national officers.[2] There are four councils within ASNT:

  1. Technical and Education
  2. Research
  3. Section Operations
  4. Certification

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 worldwide, in countries not enforcing ISO 9712 such as the European Union or Canada. The ASNT Central Certification Program (ACCP) is a fully accredited certification scheme that specifically complies with the ISO 9712 Standard.


ASNT manages a central certification scheme for Level III NDT professionals.

The Conference Department of ASNT regularly organizes two major scientific and technical conferences around March and October each year.
