This standard specifies the minimum requirements for half masks and quarter masks for use as part of respiratory protective devices, except escape apparatus and diving apparatus.
Definitions:
Half Mask = A facepiece which covers the nose, mouth and chin
Quarter Mask = A facepiece which covers nose and mouth
Description:
They are intended to provide adequate sealing on the face of the wearer against the ambient atmosphere. Air enters the facepiece and passes directly to the nose and mouth area of the facepiece through inhalation valve(s). When breathing the exhaled air flows to the ambient atmosphere via the exhalation valve(s) of the mask.
Filters
To protect from toxic agents, masks need to be used with filters, which are covered in EN 143 for particulate filters and EN 14387 for gas and combined filters (gas and particulate).
1. Resistance To Temperature
The masks are conditioned for 24h at 70°C and then for 24h at room temperature +30°C. If the facepiece and its components show no appreciable deformation the result is a pass.
2. Resistance To Flammability
The standard describes the procedure to test the masks by exposing them to a direct flame. Parts of the facepiece that might be exposed to flame during use shall either not burn or continue to burn for more than 5 seconds after the flame is removed. Resistance to temperature and flammability tests make sure the mask will maintain its performance in extreme conditions of use.
3. Breathing Resistance
The breathing resistance of the facepiece when tested with a breathing machine shall not exceed
» 2.0 millibar for inhalation
» 3.0 millibar for exhalation
This test ensures breathing is comfortable when wearing the facepiece.
4. Inward Leakage
When the facepiece is correctly fitted, the % of the ambient atmosphere outside the facepiece which is allowed to pass though the facepiece will not be greater than 2%. This test ensures the masks offers effective protection.
