1 Scope This European Standard specifies minimum performance requirements for self-contained open-circuit compressed air breathing apparatus with full face mask used as respiratory protective devices, except escape apparatus and diving apparatus. Such equipment is intended for use in work situations where the risk on over pressurisation of the pressure vessels with their valves due to hot environmental conditions is low. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

The pressure vessels shall be charged to not more than 50 % of filling pressure during conditioning. Testing shall be done in accordance with 7.3. 7 Testing 7.1 General If no special measuring devices or measuring methods are specified commonly used methods and devices should be applied. Before performing tests involving human subjects account should be taken of any national regulations concerning the medical history, examination or supervision of the test subjects. Positive pressure apparatus shall be tested as complete apparatus including the full face mask as supplied by the applicant. If not otherwise specified, two apparatus shall be tested. 7.2 Nominal values and tolerances Unless otherwise specified the values stated in this European Standard are expressed as nominal values. Except for temperature limits, values which are not stated as maxima or minima shall be subject to a tolerance of ± 5 %. Unless otherwise specified the ambient temperature for testing shall be from 16 °C to 32 °C and the temperature limits shall be subject to an accuracy of ± 1 °C. 7.3 Visual inspection The visual inspection shall be made by the test house prior to laboratory or practical performance tests. This may entail a certain amount of dismantling in accordance with the manufacturer’s instructions for maintena
