DIN EN ISO 16891:2016-12

This standard specifies a standard reference test method useful to assess the relative degradation characteristics of cleanable filter media for industrial applications under standardized simulated test conditions. The main purpose of testing is to obtain the information about relative change of properties of filter media due to exposure to the simulated gas conditions for a long time. The main target of this International Standard is the property change of nonwoven fabric filters because they are frequently used under similar circumstances to the test gas conditions described in this International Standard. The results obtained from this test method are not intended for predicting the absolute properties of full scale filter facilities. However, they are helpful for the design of a bag filter and selection and development of appropriate cleanable filter media, and for the identification of suitable operating parameters. This standard contains the German version of EN ISO 16891:2016 prepared by Technical Committee ISO/TC 142 "Cleaning equipment for air and other gases" in collaboration with Technical Committee CEN/TC 195 "Air filters for general air cleaning" of the European Committee for Standardization (CEN). The national interests during the preparation were represented by Committee NA 060-09-21 AA "Luftfilter" ("Air filters") in the Technical Section "General Ventilation" DIN Standards Committee Mechanical Engineering (NAM). Representatives of manufacturers and users of air filters as well as research and testing institutes were involved in the preparation of the standard.
