本规范涵盖了以磁粉分散形式存在于可控粘度橡胶基中的检验材料的材料和检验过程，该橡胶基通过添加一种或多种固化剂在室温下固化。用覆盖感兴趣区域的未固化橡胶对测试对象进行磁化。然后，磁性粒子迁移到由不连续性引起的漏磁场中。随着橡胶的固化，橡胶上的不连续迹象仍然存在。该产品可提供多种粘度和颜色。

This specification covers both the material and the examination process of an inspection material in the form of a dispersion of magnetic particles in a controlled viscosity rubber base that cures at room temperature by addition of one or more curing agents. The test object is magnetized with the uncured rubber covering the area of interest. The magnetic particles then migrate to the leakage field caused by the discontinuity. As the rubber cures, discontinuity indications remain in place on the rubber. The product may be supplied in a variety of viscosities and colors.
