Introduction
The test stand is designed according to ISO/DIS19713 Road vehicles - Inlet air cleaning equipment for internal combustion engines and compressors - Part 1: Fractional efficiency test. This filter particle counting method test stand is able to test the fractional efficiency of fine particles sized from 0.3μm-5μm and extended to 10μm. The particle size is subdivided into 0.3μm-0.5μm,0.5μm-1μm,1μm-3μm,3μm-5μm,5μm-10μm,≥10μm.
The design of the this test stand also takes relevant reference from American national ventilation filters standard ASHRAE52.2-1999, EN779-2002, and ISO19713
