ISO 1 2944.7 - 201 7 "Paints and varnish protective paint systems for corrosion protection of steel structures, Part 7: Implementation and supervision of paintings" specifies mainly the procedures for the implementation and supervision of paints work on steel structures. The standard addresses painting operations carried out in workshops or on site, emphasizing the importance of ensuring painting mass and long-term protection. The standard updates the definitions of terms and normative references, providing detailed implementation and supervision requirements, but does not address surface preparation, application of metallic coatings, and methods of pretreatment. Its purpose is to provide clear guidance for painting works to ensure effective corrosion protection of structures over their service life.
