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.
