CEN/TC 195 - Materiali, componenti e sistemi per la depurazione e la filtrazione di aria, gas e fumi

Data Documento: 07/10/2010
Organo Tecnico: CEN/TC 195 - Cleaning equipment for air and other gases

Note:
This standard covers methods on how to test air filters and air filter intakes systems for rotary machinery like gas turbines, compressors and for stationary internal combustion engines. The envelope for testing is in the range of 0.25 m3/s (900 m3/h) up to 1.67 m3/s (6000 m3/h) Parameters to be evaluated include fractional particle removal efficiency (0.3-1.2 um for fine filters and 1.0-5.5 um for coarse filters), airflow resistance (energy consumption), loading characteristics. This international standard applies to air filters having an initial efficiency of less than 99.98% with respect to 0.4 um particles. Part 1 of the standard refers to static elements but can be applied to other filter types when appropriate.
