GB/T 9444-2019 Steel and iron castings – Magnetic particle inspection 1 Scope This standard specifies the general requirements, acceptance criteria, classification and evaluation of indication, re-inspection, inspection records and reports of magnetic particle inspection for steel and iron castings. This standard is applicable to magnetic particle inspection of defects on the surface and near surface of ferro-magnetic steel and iron castings. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies.

The central conductor method shall be verified using the annular test block of GB/T 23906. 4.1.4 Comprehensive performance test shall be carried out before the inspection starts. Generally, standard test pieces or annular test block are used. When there is no provision by users or technical documents, A1-30/100 test pieces are recommended. A more efficient method can also be used to inspect representative workpieces with known defect types, locations, sizes, and distributions. The workpieces shall have been demagnetized and have no residual indication from previous inspections. 4.2 Ordering instructions When conducting magnetic particle inspection, the manufacturer and the purchaser shall specify the following content:
