电工非纤维质纸.第3部分:单项材料规范.表3:无填充芳纶(聚芳酰胺)纸

[中文适用范围]： IEC 60819-3 的这张表规定了四种类型的无填充芳纶纸的要求： 类型 1：压光纸；类型2：压光纸@，具有改进的抗撕裂性和贴合性；类型3：未压光纸；类型 4：较低密度的压光纸@，用于层压。符合本规范的材料符合既定的性能水平。然而，用户针对特定应用选择材料应基于该应用中充分性能所需的实际要求，而不是仅基于本规范。安全警告：本文档中包含或引用的方法的用户有责任确保以安全的方式使用它们。 [外文原描述]： IEC 60819-3-3:2011 is a sheet of IEC 60819-3 specifies requirements for four types of unfilled aramid papers: - Type 1: calendered paper; - Type 2: calendered paper, with improved tearing resistance and conformability; - Type 3: uncalendered paper; - Type 4: calendered paper, with lower density for laminating. This edition includes the following significant technical changes with respect to the previous edition: - normative references change: all the requirements are now determined according the clauses of test methods from IEC 60819-2 specific for non cellulosic papers, instead of IEC 60554-2:2001 generally valid for cellulosic papers; - and some new, very thin thicknesses, of type 4, calendered paper with lower density for laminating, were added.
