IEC 60819-3-4:20 13规定了对含有云母颗粒并指定为PAaM的两种芳族聚酰胺纤维纸的要求: -类型1:包含云母颗粒的压延芳族聚酰胺纸； -类型2:含有云母颗粒的未压延芳族聚酰胺纸。符合本规范的材料符合既定的性能水平。然而，用户对特定应用的材料的选择应基于该应用中足够性能所必需的实际要求，而不是仅基于本说明书。安全警告:本文件中包含或提及的方法的用户有责任确保以安全的方式使用它们。这第二版取消并取代了2001年出版的第一版。本版构成技术修订版。与上一版相比，本版包括以下重大技术变更:对文档进行了更新，包括表1中的新厚度和相关值。 关键词:含云母颗粒的芳纶纤维纸，PAaM，压延，未压延

IEC 60819-3-4:2013 specifies requirements for two types of aramid fibre paper containing mica particles and designated as PAaM:
- type 1: calendered aramid paper containing mica particles;
- type 2: uncalendered aramid paper containing mica particles. Materials which conform to this specification meet established levels of performance. However, the selection of material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. SAFETY WARNING: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: the document was updated including new thicknesses and relevant values as from Table 1.
