The process of harmonization of European Union standards in Ukraine, which began in the 2000s, led to appearance of about a hundred new regulatory and technical documents in the field of non-destructive quality control of metal products and the cancellation of previously valid ones. The standardization system in Ukraine is characterized by a certain closedness: lack of official texts of standards in the Ukrainian language, paid access to the standards base, sometimes lack of any texts of officially accepted documents. This led to insufficient awareness of specialists regarding the requirements of current standards. This article analyzes the main requirements and provisions of international standards in the field of capillary control, one of the frequently used types of non-destructive testing, which is conducted to detect discontinuities such as cracks, films, folds, porosity and junctions, which appear on the surface of the tested material. This testing is mainly applied to metallic materials, but it can also be used to control other materials, provided that they are inert to the influence of flaw detection materials and are not too porous (castings, forgings, welds, ceramics, etc.).15 Ref., 2 Tabl., 3 Fig.
