Papiers non cellulosiques pour usages électriques – Partie 3: Spécifications pour matériaux particuliers – Feuille 3: Papiers en aramide non chargé (polyamide aromatique) (Edition 3.0)
This 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. 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.
