It may include a pressure reducer, pressure reducer safety valve, supplementary air supply, or other components and parts.

NOTE This will enable other test houses to duplicate the tests and assess the results thereof. Testing shall be done in accordance with 6.4.2 and 6.11. 5.11 Resistance to temperature and flammability 5.11.1 Temperature performance 5.11.1.1 General The apparatus shall operate trouble-free over the temperature range of –30 °C to 60 °C. Apparatus specifically designed for temperatures beyond these limits shall be tested and the temperature(s) shall be marked on the apparatus. Apparatus shall meet the breathing resistance requirements given in 5.11.1.2 and 5.11.1.3 at the extremes of the temperature range given. 5.11.1.2 Breathing resistance at low temperatures A positive pressure shall be maintained in the half mask. The exhalation resistance shall not exc
