Ignition source
source of energy that initiates combustion
(SOURCE: ISO 13943:2008, 4.1891
4 Test apparatus
4.1 Components
The test apparatus shall comprise the following:
a) a metal enclosure (4.2);
b) an ignition source (4.3);
C) a suitable chamber (4,4).
4.2 Metal enclosure A metal enclosure (1 200土25) mm high, (300土25) mm wide and (450土25) mm deep with open front and closed top and bottom, (see Figure 1), shall be used, in order to protect the test sample from draughts. It shall be constructed of rigid sheet metal.
4.3 lgnition source The ignition source shall comply with IEC 60695-11-2, which includes a method of confirmation of the test flame, except that the laboratory fumehood/chamber shall comply with 4.4.
4.4 Chamber The metal enclosure and ignition source shall be contained within a suitable chamber, substantially free from draughts during the test duration, but with facilities for disposing of noxious gases resulting from burning. The chamber shall be maintained at a temperature of (23土10) °C.IEC 60332-1-1 pdf download.
