EN 14593-1:2005 (E) 5 Introduction A given respiratory protective device can only be approved when the individual components satisfy the requirements of the test specification, which may be a complete standard or part of a standard, and practical performance tests have been carried out successfully on complete apparatus where specified in the appropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permitted provided the respiratory characteristics and weight distribution are similar to those of the complete apparatus. 1 Scope This European Standard specifies minimum requirements for compressed air line breathing apparatus with demand valve for use with a full face mask as a respiratory protective device. Escape and diving apparatus and apparatus used in abrasive blasting operations without additional protective features are not covered by this European Standard, although certain requirements addressing the use in conjunction with escape apparatus and escape conditions are given. Laboratory and practical performance tests are included for the assessment of conformance to the requirements. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
