1.1 本参考照片集涵盖了通过干粉磁粉法检测到的钢铸件和其他类型的铁铸件中出现的不连续性的类型和程度。 1.2 这些参考照片旨在帮助对经过磁粉检测的铁铸件中发现的不连续性进行分类。 1.3 这些参考照片旨在与实际铸件上观察到的磁粉显示进行比较。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This collection of reference photographs covers types and degrees of discontinuities occurring in steel castings and other types of ferrous castings detectable by the dry powder magnetic particle method. 1.2 These reference photographs are intended to assist in the classification of those discontinuities revealed in ferrous castings subjected to magnetic particle examination. 1.3 These reference photographs are intended to be used for purposes of comparison with the magnetic particle indications observed on actual castings. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
