Respiratory protection regulations
UNE-EN 149:2001+A1:2010 Filtering half masks to protect against particles
This standard specifies the minimum requirements to be met by filtering half masks used as respiratory protective devices against particulate matter.
There are three classes of devices based on their performance and inward leakage
Filter efficiency:
- FFP1: 80 %
- FFP2: 94 %
- FFP3: 99 %
Inward leakage:
At least 46 out of 50 tests must be higher than:
- 25% FFP1
- 11% FFP2
- 5% FFP3
In addition, at least 8 of the 10 arithmetic averages must be higher than:
- 22% FFP1
- 8% FFP2
- 2% FFP3
