This proposed standard aims to provide a laboratory test method for media and devices which are used for removal of gas phase contaminants from air in general ventilation. The standard deals with granular media, fibres or pads and full size, production, gas filters where the media are incorporated. It is not aimed at technologies such as scrubbers, absorbers, non-sorptive devices or packed columns unless they fit into the specified test apparatus. Nuclear and military applications are specifically excluded.
Part 1 of the proposed standard will cover the the sorptive medium such as activated carbon, silica gel, activated alumina, molecular sieves, specialist adsorptive fibre based products as well as the sorptive capacity of traditional fibres, particulates and granules, provided they are incorporated into a filter structure.
It is proposed that the new standard will be based on the attached draft which will be expanded to incorporate detail from existing documents.
