Breathing resistance

The breathing resistance of the respirator is tested during

inhalation (continuous flow) and exhalation (cyclical flow). The

breathing resistance of the respirators shall not exceed the

following limits:

Maximum Breathing Resistance

EN 149:2001+A1:2009

Classification

Inhalation at

30l/min

FFP2

0.7 mbar

FFP3

1.0 mbar

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

EN 149:2001+A1:2009

Classification

Inhalation at 95l/min

5.0 mbar (valved

respirator)

FFP2

4.0 mbar (unvalved

respirator)

7.0 mbar (valved

respirator)

FFP3

5.0 mbar (unvalved

respirator)

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

burner flame. The respirator shall not burn or continue to burn

within 5 seconds of removal from the flame.
