SNT-TC-1A
Qualification and Certification:
MFL Inspection of Above
Ground Storage Tanks





Purpose

This qualification adds reliability and confidence to the Magnetic Flux Leakage (MFL) inspections of Above Ground Storage Tanks (AST’s), and provides assurance that technicians are of a demonstrated competence.

Qualification

It provides the first SNT-TC-1A MFL training course for the inspection of AST’s that is validated by the British Institute of Non-Destructive Testing (BINDT).

Training and examination certificates are issued by the Southwest School of NDT (SWS of NDT), an ISO9001 accredited and BINDT approved training and examination centre for Non-destructives Testing methods.

It provides an independently verified combined Level 1 and 2 qualification for SNT certification against a published Written Practice.

Course Content

The 80 hour combined Level I/Level 2 course and examinations cover the General Theory of MFL, the Specific Theory of controlling codes and specifications and practical application using modern MFL equipment.

It is aligned with syllabus published by ASNT standard Topical Outlines for Qualification of NDT personnel ANSI/ASNT CP- 105-2006 and the qualification, examinations and certification are based on the ASNT recommended practice SNT-TC-1A as documented in a specific and detailed written practice provided as part of the course.

Who’s Involved

The course has been developed jointly by the Southwest School of NDT and Silverwing, a leading manufacturer of MFL inspection systems.

The instructors delivering the course are qualified and experienced MFL inspectors who have extensive knowledge of the application and conditions faced by technicians in the field.

Location

The course is conducted at Silverwing’s dedicated training facility located in Swansea, UK which is a remote training centre for the SWS of NDT.

This facility provides the latest MFL scanners and holds a number of real and manufactured training and examination samples designed to reflect the detection requirements of MFL.

Controlling Specifications and Codes
