ISO/TC 142 - Materiali, componenti e sistemi per la depurazione e la filtrazione di aria, gas e fumi

Data Documento: 22/10/2009
Organo Tecnico: ISO/TC 142 - 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 against particle contamination. The standard is based upon ISO-TS-21 220. 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).This international standard applies to air filters having an initial efficiency up to 99,5% with respect to 0,4 ìm particles. Filters in the higher end and above 99,95% initial efficiency are tested and classified according to other standards.
