本文件规定了两种低电压试验，用于检测和定位玻璃和搪瓷涂层中延伸至基底金属的缺陷。 方法A（电气）适用于快速检测和确定缺陷的一般位置。基于颜色效果的方法B（光学）适用于更精确地检测缺陷及其确切位置。这两种方法通常适用于平面。对于更复杂的形状，如波状和/或波纹表面，ISO 8289-2适用。交叉引用:IEC 60086-2ISO 2746ISO 8289-2购买时可用的所有现行修订版均包含在本文件的购买中。

This document specifies two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings. Method A (electrical) is applicable to the rapid detection and determination of the general location of defects. Method B (optical), based on colour effects, is applicable to the more precise detection of defects and their exact locations. Both methods are commonly applied to flat surfaces. For more intricate shapes, such as undulated and/or corrugated surfaces, ISO 8289-2 is applicable.Cross References:IEC 60086-2ISO 2746ISO 8289-2All current amendments available at time of purchase are included with the purchase of this document.
