|
Korean certification regulation for particulate respirator requires total inward leakage (TIL) test as European Standards (EN) and the standard levels of regulation are the same as those of EN. This study was conducted to evaluate particulate respirator being commercially used in the market by TIL and to evaluate validity of the certification test in Korea. Two full face masks, three half masks and 10 filtering facepieces (two top-class, four 1st-class and four 2nd-class), total 15 brands respirators, and 10 test panels (subjects) who were classified in 9 facial grids in accordance with face length and lip length, were selected for test. TIL tests were conducted in the laboratory of 3M Innovation Center which was established by EN standard. As expected TILs of full face masks were the lowest in three types and TILs of half masks and filtering facepieces showed statistically significant difference in manufacturers.
