21、art of IEC 60332 specifies the test apparatus for testing the resistance to vertical flame propagation for a single small vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions. The procedure, together with an informative annex of recommended requirements for

22、 performance, is given in IEC 60332-2-2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendm

24、pplies. The definition is taken from IEC 60695-4. 3.1 ignition source source of energy that initiates combustion IEC 60695-4:1993, definition 2.76 4 Test apparatus 4.1 Components The test apparatus shall comprise the following: a) a metallic screen (4.2); b) an ignition source (4.3); c) a suitable c

25、hamber (4.4). Page4 EN6033221:2004-23306-21 4002:CEI 5 4.2 Metallic screen A metallic screen (1 200 25) mm high, (300 25) mm wide and (450 25) mm deep with open front and closed top and bottom, (see Figure 1), shall be used. 4.3 Ignition source The ignition source shall be a propane burner complying

26、 with Figure 2. NOTE In order to obtain the 8 mm bore, as shown in Figure 2, it is permitted to fit an adaptor to burners not otherwise complying. The burner shall be fed with technical grade propane of greater than 95 % purity, and shall produce a luminous flame when in a vertical position with the

27、 air inlet closed. The gas flow shall be adjusted so that the total length of the luminous flame is (125 25) mm (see Figure 3). 4.4 Chamber The metallic screen and ignition source shall be contained within a suitable chamber, substantially free from draughts during the test duration, but with facili

28、ties for disposing of noxious gases resulting from burning. The chamber shall be maintained at a temperature of (23 10) C. NOTE 1 If the requirement for the draught-free closed area is met by the use of a standard fume cupboard, it must be capable of independent operator control of the extractor fan

29、 such as to permit operation with the extractor “OFF“. Some fume cupboards may not be supplied with this facility. NOTE 2 If a fume cupboard is used as the draught-free test area, the following safe operating practice is recommended: a) turn off extractor fan, seal the outlet; b) pull down front doo

30、r of fume cupboard to leave a gap sufficient to manipulate burner into position; c) ensure operator is protected; d) do not move the door of the fume cupboard during the test; e) at the end of the test evacuate the fume cupboard fully before opening the door.
