BS EN 50200:2015 pdf download – Method of test for resistance to fire of unprotected small cables for use in emergency circuits This European Standard is applicable to cables for emergency circuits of rated voltage not exceeding600 V/1 00o v, including those of rated voltage below 80 V and optical fibre cables. This European Standard includes details for the specific point of failure,continuity checking arrangement,test sample, test procedure and test report relevant to electric power and control cables with rated voltage upto and including 600 v/1 000 v.Details for the specific point of failure, continuity checking arrangement, testsample, test procedure and test report relevant to copper data and telecom cables and optical cables aregiven in the relevant standards of CiLc/TC 46x and CLcTC 86A. The test method is limited to cables with an overall diameter not exceeding 20 mm. The test method is based on the direct impingement of flame from a propane burner giving a constanttemperature attack of a notional 842 °C. lt is intended to be used for cables for emergency circuits suitablefor alarm, emergency lighting and communication. NOTE When the test method is used in support of EN 13501-3, it only applies to cables of less than 20 mmdiameter, and,for metallic conductor cables, to those with conductor sizes up to and including 2,5 mm2.For opticalcables, only the less than 20 mm diameter limit applies. This European Standard includes(Annex B) the field of direct application and rules for extended applicationof test results (EXAP). Details regarding classification using data from this test are given in EN 13501-3 1).lnformation regarding classification is given in Annex D. This European Standard also includes informative guidance (AnnexE) on a means of applying a water sprayto the cable during the test. Such a requirement may be a feature of particular product standards.
