适用于用于电气绝缘目的的陶瓷、玻璃和玻璃陶瓷材料。指定测试方法。旨在提供试样加工材料的典型试验结果。由于在大多数情况下，用于绝缘目的的陶瓷部件与试件的尺寸和形状截然不同，因此此类测试的结果只能为部件的实际性能提供指导。在相关情况下，讨论了成形和加工方法所施加的限制。

Applicable to ceramic, glass and glass-ceramic materials to be used for electrical insulation purposes. Specifies methods of test. Intended to provide test results typical of the material from which the test pieces are processed. Since, in the majority of cases, ceramic components for insulating purposes are of rather different size and shape to test pieces, the results of such tests provide only a guide to the actual properties of components. The limitations imposed by the method of forming and processing are discussed where relevant.
