This standard specifies a method for detecting changes in the wall thickness of ferromagnetic pipe fittings by means of external magnetization. It is suitable for ferromagnetic pipe fittings (excluding welded pipes) with an outer diameter of not less than 10 mm and a wall thickness of not more than 20 mm. The standard describes in detail the implementation steps, technical requirements and evaluation of results of the detection method to ensure accurate detection of the wall thickness loss of pipe fittings. It is widely used for quality control during manufacturing, processing and repair.
