scope:

This standard applies to filters assemblies for use in clean room facilities. The purpose of this stanadard is to test the filter assembly for the potential of flame spread and the amount of smoke being released during the Fire Exposure Test. The filter assembly typically consists of frames, filter media, gaskets, sealing gel material and potting compounds.

The standard does not assess the filter assembly's ability to filter contaminates during normal operation or in a fire situation.

Purpose

This standard states test requirements and procedures for the evaluation of materials used to manufacture filter assemblies for use in cleanrooms. Filter assemblies are used by the semiconductor industry, food preparation industry and pharmaceutical industry to filter incoming air in to the room. Filter assemblies fabricated from materials that do not meet these requirements are considered to be a fire and smoke hazard and require special protection for potential fire scenarios.
