There are threetest methods used to classify surgical masks:
有三种测试方法用来给外科口罩进行分类:
1. BacterialFiltration Efficiency in vitro (BFE) (ASTM F2101-零7)
体外细菌过滤率(BFE)(ASTM F2101-零7)
Classification:
分类
BFE => 95% TYPE I
BFE => 98% TYPE II
2. BreathingResistance (Delta P)
呼吸阻抗 它是指气体在流经呼吸道及呼吸装置时的耗功加总值。
3. SplashResistance (ASTMF1862-07)
防溅阻力 指防止血液体液等溅撒 物的阻止能力.
Test is used to determine the resistance penetration of potentially contaminated fluid splashes.
