DANSK DS/EN ISO 10121-2 PDF

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 2 of the proposed standard will cover the most common types of sorptive devices. It is proposed that the new standard will be based on the attached draft which will be expanded to incorporate detail from existing documents.
