Brief History – SNT-TC-1A – Over 40 years
2007 marks the publication of the latest edition of SNT-TC-1A[1]. It is now 40 years since the issue of the first edition and this paper will take a brief look at the development of the employer based certification programme and consider the differences between the various editions published over the past 40 years
What is SNT-TC-1A The first edition of SNT-TC-1A was published in 1966 – its title is derived as follows: SNT- Society of Nondestructive Testing TC – Technical Committee 1A – 1st Committee was given this title The purpose of this document was to provide a set of guidelines for NDT operator certification.
The 2006 edition (published in February 2007) is the 12th edition and is now available. the document is not and has never been a Standard - it contains guidelines which the Employer uses to create a Written Practice. SNT-TC-1A is a Recommended Practice. It is further made clear that the Written Practice created must be acceptable, not only to the Employer, but also to the Purchaser

Each edition requires the Employer to establish a Written Practice. SNT-TC-1A proposes that the guidelines may be modified by the Employer to suit his needs but the Written Practice created must always take account of the needs of the purchaser of the NDT services. 5.1 Definitions In 1966 only 3 terms were defined – qualification, certification and certifying agency. By 2006 15 terms were defined including NDT, Outside Agency and Limited Certification reflecting changing times.
5.2 Methods - Main 1966 5 methods recognised UT,MT,PT,& ET(in 1984 ET became Electromagnetic Testing and in 2006 became subdivided into 4 techniques - AC Field; Eddy current; Electromagnetic Testing; Flux Leakage and Remote Field) & RT 1974 Neutron Radiography and Leak Testing (4 techniques) added 1980 Acoustic Emission 1988 Visual Testing 1992 Infra-red Thermography 1996 (1) Vibration Analysis 2001 Laser Testing (2 techniques) 2006 Magnetic Flux Leakage Total methods by 2006 – 13

Some important Points 1. SNT-TC-1A – Trg hrs takes into account the edu.qualification
Experience hrs are same irrespective edu.Qualification
CP-189 Trg &exp. Hrs are same &no discrimination based on edu.Qual
2. Trg hrs are same for 5 main methods for both namely 40 (40) and 210 (400) for Lev.I and 630 and 1200 for lev.II for AET, Laser Testing (Holography),ET (4),RT & UT namely 40 (40) & 210 (400) & 630(1200)hrs PT & VT& Laser (profilometry) exp.Same 70(130)140 (270)
Hints ( my view) A person working for 210 hrs in NDT and working 50% of time on RT & 50% on UT can claim 210 hrs of work experience for both RT & UT and also claim 210 hrs of NDT Same is the case with 25% & 4 methods(enq)

10. Weighting Factors From 1966 - 1988 the Employer decided his own weighting factors (within the limits supplied in SNT-TC-1A and put them into the Written Practice. In 1988, however, the weighting factors were removed and replaced by simple averaging (however, all flaws in the practical test are to be located to pass the practical test).
