| Abstract: | In this article, filter efficiency behavior under loading condition and the effect to real application was described together with introduction of NIOSH standard about particle filter efficiency test. NIOSH＇s new method of end-of-test-judgment with oil aerosol was also introduced which was developed to address the same problenls occurred in China. Based on feasibility discussion, suggestion was made that is to adopt NIOSH new method in GB2626 in future. |
