What is EN ISO 9934-4:2017 ?

Magnetic particle testing is a non-destructive testing (NDT) technique that uses a magnetic powder as a sample to detect surface and subsurface defects in ferromagnetic materials. The magnetic powder is applied to the surface of the material and then agitated to release any particles that may be present. The particles are then detected using a device such as a magnetic field strength analyzer or a particle counter.

Magnetic particle testing is a popular NDT technique because it is non-destructive, meaning that it does not cause any damage to the material being tested. It is also highly sensitive and can detect even small particles that may be present.

The purpose of EN ISO 9934-4:2017 is to provide guidelines for the design, installation, and use of equipment used in magnetic particle testing. It covers topics such as the selection of equipment, the training of personnel, and the procedures for conducting magnetic particle testing.

The standard provides requirements for the design and construction of magnetic particle testing equipment, including the accuracy and reliability of the equipment, the environmental conditions in which the equipment can be used, and the level of maintenance required. It also provides guidelines for the testing procedures, including the selection of the magnetic powder and the testing parameters that should be used.

EN ISO 9934-4:2017 is intended to ensure that magnetic particle testing equipment is designed, installed, and used in a safe and effective manner, and that the results of the testing are reliable and accurate. Compliance with the standard is often required in industries such as manufacturing, automotive, aviation, and construction, to ensure the safety and reliability of the magnetic particle testing equipment.
