Lengths of 3,5 m of cables shall be used. The lower part of the electric cables shall be 20 cm under the lower edge of the burner. The cables shall be positioned in the middle of the ladder (with respect to its width).\nEach test piece or bundle shall be attached individually to each rung of the ladder by means of a metal wire (steel or copper). For electric cables up to and including 50 mm diameter, use wire between 0,5 mm and up to and including 1,0 mm in diameter. For cables above 50 mm diameter use wire between 1,0 mm and 1,5 mm in diameter.\nWhen mounting the test pieces, the first test piece shall be positioned approximately in the centre of the ladder and further test pieces shall be added on either side so that the whole array of test pieces is approximately centred on the ladder.\nThe spacing and bundling is explained further below.\nAt each height of 25 cm a horizontal line shall be drawn in order to measure the flame spread as a function of time. The first line (i.e. zero line) shall be at the same height as the burner.\nThe cables shall be mounted as follows depending on the classification that is applied for.\n1.1.1.\nClass B2ca, Cca and class Dca\nThe selected mounting procedure depends on the electric cable diameter according to Table 4.1.\nTable 4.1\nMOUNTING AS A FUNCTION OF CABLE DIAMETER\nCable diameter\nMounting\nLarger than or equal to 20 mm\n20 mm spacing between cables\nBetween 5 and 20 mm\nOne cable diameter spacing between cables\nLess than or equal to 5 mm\nThe cables shall be bundled in bundles of 10 mm diameter. The bundles shall not be twisted. The spacing between bundles shall be 10 mm.\nThe threshold values are determined with the diameter rounded to nearest mm, except for cables with a diameter of less than 5 mm, where the diameter shall not be rounded.\nThe following formulae are used for determination of the number of cable lengths per test.\n1.1.1.1.\nFor cables with diameter greater than or equal to 20 mm\nThe number of cables, N, is given by:\nN = int 300 + 20 d c + 20 … equation 1\nwhere:\ndc is the diameter of the cable (in mm and rounded to the nearest mm).\nint function = the integer part of the result (i.e. the value rounded down).\n1.1.1.2.\nFor cables with a diameter greater than 5 mm but less than 20 mm\nThe number of cables, N, is given by:\nN = int 300 + d c 2 d c … equation 2\nwhere:\ndc is the diameter of the cable (in mm and rounded).\nint function = the integer part of the result (i.e. the value rounded down).\n1.1.1.3.\nFor cables or wires with a diameter less than or equal to 5 mm\nThe number of 10 mm bundles, Nbu, of cables is given by:\nN bu = int 300 + 10 20 = 15 … equation 3\nThus 15 bundles with 10 mm distance between the bundles shall be mounted.\nThe number of cables in each bundle (n) is:\nn = int 100 d 2 c … equation 4\nwhere:\ndc is the diameter of the cable (in mm and not rounded).\nThe number of cable lengths (CL) for wires or cables with a diameter less than 5 mm will hence be:\nCL = n × 15 … equation 5\n1.1.1.4.\nTotal length of cable per test\nThe total length L (m) per test is:\nL = n × 15 × 3,5 for dc ≤ 5 mm\nor\nL = N × 3,5 for dc > 5 mm … equation 6\n1.1.2.\nClass B1ca\nAt the back of the cable tray a non-combustible calcium silicate board shall be mounted with a density 870 ± 50 kg/m3 and a thickness of 11 ± 2 mm. This board can be mounted in two parts.\nIn all other aspects the mounting of the cables is identical to class B2ca, Cca and Dca.\n2.\nDefinitions of test parameters\nTable 4.2\nDEFINITIONS OF TEST PARAMETERS IN FIPEC20 SCENARIOS 1 AND 2\nAll calculated parameters are evaluated during 20 minutes from test start (ignition of burner).\nParameter\nExplanation\nTest start\nIgnition of burner\nEnd of test\n20 minutes after ignition of burner (End of period for calculation of parameters)\nHRRsm30, kW\nHeat Release Rate averaged by a 30-s sliding average\nSPRsm60, m2/s\nSmoke Production Rate averaged by a 60-s sliding average\nPeak HRR, kW\nMaximum of HRRsm30 between test start and end of test, excluded contribution from ignition source\nPeak SPR, m2/s\nMaximum of SPRsm60 between test start and end of test\nTHR1 200, MJ\nTotal Heat Release (HRRsm30) from test start until end of test, excluded contribution from ignition source\nTSP1 200, m2\nTotal Smoke Production (HRRsm60) from test start until end of test\nFIGRA, W/s\nFIre Growth RAte index defined as the highest value of the quotient between HRRsm30 excluding the contribution of ignition source and time.
