Breathing resistance
The breathing resistance of the respirator is tested during
inhalation and exhalation. The breathing resistance of the
respirators shall not exceed the following limits:
Maximum Breathing Resistance

+A1:2009
Inhalation
classification
at 30l/min
FFP1

Clogging
For single shift use respirators (NR), the clogging test
is optional. For re-usable respirators (R) this test is mandatory.
The respirators are loaded with very high amount of Dolomite
dust which will tend to clog the filter. After loading with the
required amount of dust, the breathing resistance of the
respirators shall not exceed the following limits:
Maximum Breathing Resistance

Flammability
Tested respirators are mounted on a metallic head which
rotates with a linear speed of 60mm/s. The respirators are
passed within 20mm of the tip of an 800°C (±50°C) propane
burner flame. The respirator shall not burn or continue to burn
within 5 seconds of removal from the flame.
