T/CAAMM 17-2018 Towards the parts of the tractor, magnetic particle testing method
Basic Information
Scope
Main technical content: This standard specifies the terms and definitions of magnetic particle inspection methods for tractor parts, the qualifications of inspectors, drawing marks, process procedures and process cards, inspection procedures, requirements for the surface of parts, inspection equipment, inspection media, standard specimens, types of magnetizing current and their selection, magnetizing techniques (magnetizing methods) and their selection, magnetic field strength (or magnetizing specifications), inspection methods, on-site environmental requirements, performance testing of inspection systems, classification of magnetic flaw display, evaluation and quality grading, demagnetization, inspection reports, and original records of online production inspections. This standard applies to magnetic particle inspections of finished, semi-finished, and raw materials used in the manufacture of tractor parts, as well as surface and near-surface defects of forgings, castings, and welded joints. Agricultural machinery-related parts can refer to this standard for magnetic particle inspections.
