3 Classification 分类

Particle filtering half masks are classified according to their filtering efficiency and their

maximum total inward leakage. There are three classes of devices: FFP1, FFP2 and FFP3. The

protection provided by an FFP2 - or FFP3 - device includes that provided by the device of

lower class or classes.

根据过滤效率和最大总向内泄漏量对粒子过滤半面罩进行了分类。

有三类:FFP1、FFP2 和FFP3。

由FFP2 -或FFP3 -设备提供的保护包括由-个或多个较低级别的设备提供的保护。

In addition, particle filtering half masks are classified as single shift use only or as re -usable

(more than one shift).

此外，粒子过滤半面罩分为- -次性使用或可重复使用。
