标准摘要
[中文适用范围]： 本标准规定了金属磁记忆（MMM）技术无损检测（NDT）的术语和定义以及应用该技术的磁性检测方法的一般要求。 本文件中规定的术语对于使用金属磁记忆技术的无损检测的所有类型的文档和文献中的应用都是强制性的。 该无损检测技术具有以下目标： ——确定铁磁物体磁机械状态的不均匀性，检测缺陷浓度和金属微观结构不均匀性的边界； ——确定具有磁杂散场畸变的位置，以进行进一步的微观结构分析和/或无损检测和评估； ——受检对象疲劳损伤的早期诊断并评估其结构寿命； ——根据磁性异质性对新的和用过的检查对象进行快速分类，以进行进一步的测试； ——通过将金属磁记忆检测与其他无损检测方法或技术（超声波检测、X射线等）相结合，快速检测最可能的缺陷位置，提高无损检测的效率； ——各类焊接接头及其实施方式（包括接触焊和点焊）的质量控制。 有关此应用的详细信息，请参阅 ISO 24497-2。 [外文原描述]： This document specifies terms and definitions for non-destructive testing (NDT) by the technique of metal magnetic memory (MMM) as well as general requirements for application of this technique of the magnetic testing method. The terms specified in this document are mandatory for application in all types of documentation and literature of non-destructive testing, using the metal magnetic memory technique. This NDT technique has the following objectives: — determination of the heterogeneity of the magneto-mechanical state of ferromagnetic objects, detection of defect concentration and boundaries of metal microstructure heterogeneity; — determination of locations with magnetic stray field aberrations for further microstructural analysis and/or non-destructive testing and evaluation; — early diagnostics of fatigue damage of the inspected object and evaluation of its structural life time; — quick sorting of new and used inspection objects by their magnetic heterogeneity for further testing; — efficiency improvement of non-destructive testing by combining metal magnetic memory testing with other NDT methods or techniques (ultrasonic testing, x-ray, etc.) by fast detection of the most probable defect locations; — quality control of welded joints of various types and their embodiment (including contact and spot welding). See ISO 24497-2 for details of this application.
