定义适用于组合云母材料、基于它们的产品和云母纸的试验方法。 与上一版相比，主要变化如下: a） 所有条款都重新编号。 b） ISO 67的相关模板已作为附录A添加到本标准中。 c） 第8条:抗拉强度和断裂伸长率 程序修改为“移动速度”，而不是“时间限制”。与增强和/或浸渍云母相比，生云母的移动速度不同。 d） 第11条:刚度 修改了试样的尺寸。 对措辞进行了修改，以使本标准涵盖使用除玻璃编织布以外的载体的材料和三层材料。术语“机器方向”和“横向”的修订（第二版（1987年）中这些术语不正确） e） 第13条:弹性压缩和塑性压缩 堆叠高度的测量公差更改为0.01 mm以内。 程序中的压力变化时间改为1分钟。 f） 第16条:电强度 根据第二版（1987）修正案1（1994）进行修改。 变更与最新版IEC 60243-1有关。 g） 第19条:缺陷和导电颗粒的检测 修订的子条款。

Defines the methods of test which are applicable to built-up mica materials, products based on them and mica paper. The main changes from the previous edition are as follows: a) All clauses re-numbered. b) Relevant template of ISO 67 has been added to this standard as Annex A. c) Clause 8: Tensile strength and elongation at break Procedure modified to give "rate of movement" instead of "time limit". Different rate of movement for raw mica as opposed to reinforced and/or impregnated mica. d) Clause 11: Stiffness Size of test specimen revised. Wording modified so that standard covers materials using carriers other than woven glass cloth and materials that are 3-ply. Revision of terms ""machine direction" and "transverse direction". (These were incorrect in second edition (1987).) e) Clause 13: Elastic compression and plastic compression Tolerance on measurement of height of stack changed to within 0,01 mm. Times for change in pressure in procedure changed to 1 min. f) Clause 16: Electric strength Modified in line with Amendment 1 (1994) to the second edition (1987). Changes relate to latest edition of IEC 60243-1. g) Clause 19: Detection of defects and conductive particles Revised subclause.
