What are the ASNT standards?
ASNT-TC1A, ASNT CP – 189 and ISO 9712 lay out specific requirements in training hours, eye exams, test questions, hours of experience, specific, general, and practical examinations. Many U.S. Corporations have implemented ISO 9001 but not ISO 9712. Almost all US companies follow ASNT TC1A as it is recognized all over the world when it comes to Qualification and Certification of Non-Destructive Testing Personnel. It was here before ISO and US industry still uses it very specifically. Nothing in 9001 requires industry to change because ASNT TC1A is recognized through ASTM.
