Air intake filter systems for rotary machinery - Test methods - Part 1: Static filter elements (ISO 29461-1:2013); German version EN ISO 29461-1:2013
prEN ISO 29461-1 "Air intake filter systems for rotary machinery -Test methods - Part 1: Static filter elements" was prepared by Technical Committee ISO/TC 142 "Cleaning Equipment for Air and other Gases" in collaboration with the Technical Committee CEN/TC 195 "Air filters for general air cleaning". prEN ISO 29461 covers methods on how to test air filters and air filter intake systems for rotary machinery like gas turbines, compressors and for stationary internal combustion engines against particle contamination. 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 standard applies to air filters having an initial efficiency up to 99,5% with respect to 0,4 m particles. Filters in the higher end and above 99,95% initial efficiency are tested and classified according to other standards. Part 1 of the standard refers to static (barrier) filter systems but can be applied to other filter types and systems when applicable. Two methods of determining the efficiency are used in this standard: - Particle efficiency (efficiency measured in respect to particle number and size) - Gravimetric efficiency (The weighted mass removal of loading dust).
