EN 404:2005 (E) 12 After completion of the activities the test subjects are asked to answer the questions in 6.6 of
EN 13274-2:2001. These answers will be used by the test house to determine if the apparatus passes or fails. If for any reason practical performance tests underground are not permissible, then the test house shall conduct simulated realistic equivalent tests, describe these tests, and provide the results thereof so that other test houses can duplicate the tests and assess the results. Testing shall be done in accordance with 7.5. 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. NOTE For summary of testing see Table 6. 7.2 Nominal values and tolerances Unless otherwise specified, the values stated in this document 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, but for the mechanical tests from 10 °C to 30 °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 maintenance. The visual inspection shall include the assessment of the device marking and information supplied by the manufacturer and any safety data sheets (if applicable) or declarations relevant to the materials used in its construction. 7.4 Conditioning 7.4.1 General Where, as specified in Table 6, conditioning before subsequent testing is required, the procedure shall be one of those described in 7.4.2, 7.4.3, 7.4.4 or 7.5.2. 7.4.2 Mechanical strength test Three filter self-rescuers shall be tested.
