Surface and near-surface defects of ferromagnetic materials and products in the field. GB/T 15822 aims to standardize magnetic particle testing activities. GB/T 15822 is intended to consist of three parts. Part 1.General. The purpose is to specify the general requirements for magnetic particle testing. Part 2.Test media. The purpose is to specify the magnetic particle testing products (including magnetic suspensions, dry magnetic particles, carrier fluids and contrast enhancement The main characteristics of agents and their performance verification methods. Part 3.Equipment. The purpose is to specify the minimum requirements for the performance, practicality and measurement characteristics of equipment used for magnetic particle testing. Parameters of the method. This document is Part 1 of GB/T 15822.This revision of GB/T 15822.1-2005 clarifies and refines the inspected workpieces. The requirements for surface preparation, magnetization technology, test medium requirements and application, and the recording and interpretation of test results promote the standardization of magnetic particle testing. It is of great significance to ensure product quality and service safety. Non-destructive testing-Magnetic particle testing-Part 1.General1 ScopeThis document specifies the general principles for magnetic particle testing of ferromagnetic materials. Magnetic particle testing is primarily used to detect surface-opening discontinuities, especially cracks. Magnetic particle testing can also detect near-surface discontinuities, but its sensitivity decreases rapidly with depth. This document specifies the surface preparation of the workpiece to be inspected, the magnetization technique, the requirements and application of the test medium, and the recording and interpretation of the test results. This document does not address acceptance criteria. Additional requirements for magnetic particle testing of special workpieces are specified by product standards. This document does not apply to the residual magnetism method.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.
