31、five test pieces. Extend the test piece horizontally using a supporting device (4.2) without creating a confinement. Light the test piece at one end and measure the time taken for the flame to appear at the other end using the stopwatch. Record this time or, if the test piece fails to burn along its
32、 complete length, record the result as failed. 6.3 Confined test Carry out the following procedure on five test pieces. Place the test piece in the steel tube through the wooden plug so that the length of the test piece outside the tube, at the same end as the plug, is (50 5) mm (see Figure 1). Fill
33、 the tube with the sand while maintaining the test piece under slight tension. Close the tube with the cardboard disc, threading the test piece through the hole of the disc. Ensure that the length of the test piece outside the tube at this end is 200 mm. Light the test piece at the shorter end and m
34、easure the time taken for the flame to appear at the other end of the test piece using the stopwatch. Record this time or, if the test piece fails to burn along its complete length, record the result as failed. 7 Test report The test report shall conform EN ISO/IEC 17025. In addition, the following
35、information shall be given: a) the atmospheric pressure during testing; b) the result of the five tests for each configuration (confined/unconfined) in the form of each burning duration (s) for a length of one metre, or failed.
