Abstract

The article presents the main properties of flaw detection materials for conducting magnetic particle inspection based on the analysis of GOST R ISO 9934-2–2011. A description of the verification of each parameter of flaw detection materials is presented and it is established how their nonconformity affects the effectiveness of control. The types of tests and which subjects should conduct them are shown. An experimental check of the detectability of defects depending on the particle sizes of flaw-detecting materials was carried out and it was found that the highest detectability is characteristic of a flaw-detecting material with a particle size of magnetic powder in the range of 0–15 microns.
