What is ACFM Testing?

Alternating Current Field Measurement or ACFM is an electromagnetic inspection technique that introduces an alternating current into the surface of the component to detect surface-breaking cracks.

The presence of a crack disturbs the electromagnetic field and the return signal is instantaneously converted by advanced mathematical techniques, so that the operator is alerted to the presence of a defect. Immediate defect sizing and recording is a major benefit compared to alternative NDT methods.

What are the responsibilities of a individual who is certified to ACFM Level 1?

An individual certified to ACFM Level 1 has to demonstrate competence to carry out NDT according to written instructions and under the supervision of Level 2 or Level 3 personnel. Within the scope of the competence defined on the certificate, ACFM Level 1 personnel may be authorised by the employer to perform the following in accordance with NDT instructions:

  • Set up ACFM testing equipment
  • Perform the ACFM inspection tests
  • Record and classify the results of the tests according to written criteria
  • Report the results

Level 1 certified personnel shall neither be responsible for the choice of test method or technique to be used, nor for the interpretation of test results.

We can provide ACFM training suitable for PCN/EN473/ISO 9712 Levels 1 and 2. Alternatively we can provide training suitable for candidates working to an employer written practice based on SNT-TC-1A; EN4179 and NAS410.

Examinations for ACFM are based around the PCN personal certification examinations to Levels 1 and 2, plus examination for employer based schemes such as SNT-TC-1A, NAS410 and EN4179.

The ACFM Level 1 examination includes a general theory paper, specific paper, and a practical exam.

The PCN requirements for Level 1 ACFM are: 40 hours training, previous to the exam, and 3 months supervised work experience, to be obtained either before the examination, or within 24 months after passing the exam.

Once the 40 hours training have been obtained, the examination passed, and 3 months supervised work experience obtained within 24 months of passing the exam, PCN will issue certification.

The options for ACFM Level 1 examinations are:
Initial Candidate
Resit (Theory)
Resit (Practical)
Recertification

Please Note: PCN require that an exam levy is paid at the appropriate rate

To be eligible for the PCN Level 1 examination, an eye test must be passed (near vision and colour).

The PCN requirements for ACFM Level 1 are: 3 month supervised work experience, to be obtained either before the examination, or within 24 months after passing the exam.

Once the 40 hours training have been obtained, the examination passed, and 3 month supervised work experience obtained within 24 months of passing the exam, PCN will issue certification.

For employer based schemes the expected amount of work experience should be determined in the written practice.
