Experimental comparison of the particle counting method in China’s national standard GB/T 6165—2008 with some foreign standards

Performs the experimental comparison evaluation with the evaluation base of MPPS efficiency for filtration units. Presents the key performance factors of reference filters and key testing factors. As a result, the particle counting method regulated in the national standard approaches that in American standard, and its result is closer to that given by the reference MPPS tests than the current EU and JIS standards, and the national standard could meet the requirements of the international market.
