IEC 60819-3-4 Ed. 2.0 b:2013

Non-cellulosic papers for electrical purposes - Part 3: Specifications for individual materials - Sheet 4: Aramid fibre paper containing not more than 50 % of mica particles


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. Keywords: aramid fibre paper containing mica particles, PAaM, calendered, uncalendered
