口罩ASTM F2100测试与EN14683测试区别
BFE,Delta P,合成血液可以适用于这两个标准,这意味着你不需要执行两次(尽管在血液上,你不能执行低压力,并将其计算为EN14683,因为他们不接受像ASTM F2100那样的低压)。EN14683不要求PFE和可燃性,所以这些只适用于ASTM F2100。然后EN14683还有一个ASTM F2100不需要的测试,那就是微生物清洁度。
ASTM F2100, Standard Specification for Performance Materials Used in Medical Face Masks, has a table that lists performance classes. It includes five different tests as listed below:
