ACFM Certification

The ACFM technique has been accepted by major organisations in the Oil and Gas, Petrochemical, Nuclear and Aerospace Industries. Approvals take different forms, they are issued by the asset owner, insurance companies or certification bodies.

For the Oil and Gas Industries a number of the certifying authorities have either been involved directly, or reviewed, the large amount of performance data, and have approved the use of ACFM.

ACFM has been approved by Lloyds, ABS, BV, DNV, and OCB Germanischer Lloyd for the inspection of offshore installations. In the case of Lloyds and ABS they have not issued formal approval certificates, but simply approve on a case by case basis.

In addition to these, documents of recommended practice (or procedures for use) for (or including) ACFM have been issued by ASTM (E2261-03), ABS (Guide for Nondestructive Inspection of Hull Welds, September 2002 edition) and COFREND (Recommendation pour le controle des soudures par la mesure du champ d'un courant alternatif, July 2003) and are being produced by ASNT and ASME.
