Recommended Practice No. SNT-TC-1A, 2011 Edition, and ASNT Standard Topical Outlines for Qualification of Nondestructive Testing Personnel (ANSI/ASNT CP-105-2011)


Recommended Practice No. SNT-TC-1A: Personnel Qualification and Certification in Nondestructive Testing (2011) provides guidelines for employers to establish in-house certification programs for the qualification and certification of nondestructive testing personnel. Since 1966, employers have used this industry-valued document as the general framework for their NDT certification programs. The newly approved ANSI Standard, ANSI/ASNT CP-105: Training Outlines for Qualification of Nondestructive Personnel (2011), replaces “Recommended Training Course Outlines” in Recommended Practice No. SNT-TC-1A: Personnel Qualification and Certification in Nondestructive Testing (2001) and is included with the SNT-TC-1A (2011).
