32、ame 1 Scope This part of IEC 60332 specifies the procedure for testing the resistance to vertical flame propagation for a single vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions. The apparatus is given in IEC 60332-1-1. NOTE 1 Testing to IEC 60332-1-2 m
33、ay be performed simultaneously with that to IEC 60332-1-3 if required. Recommended requirements for performance are given in Annex A. IEC 60332-1-2 specifies the use of a 1 kW pre-mixed flame and is for general use, except that the procedure specified may not be suitable for the testing of small sin
34、gle insulated conductors or cables of less than 0,5 mm total cross-section because the conductor melts before the test is completed, or for the testing of small optical fibre cables because the cable is broken before the test is completed. In these cases, the procedure given in IEC 60332-2-2 is reco
35、mmended. NOTE 2 Since the use of insulated conductor or cable which retards flame propagation and complies with the recommended requirements of this standard is not sufficient by itself to prevent propagation of fire under all conditions of installation, it is recommended that wherever the risk of p
36、ropagation is high, for example in long vertical runs of bunches of cables, special installation precautions should also be taken. It cannot be assumed that because the sample of cable complies with the performance requirements recommended in this standard, that a bunch of cables will behave in a si
37、milar manner. (See IEC 60332-3 series.) 2 Normative references The following referenced documents are indispensable for the application of this document.

The definitions are taken from IEC 60695-4. 3.1 ignition source source of energy that initiates combustion 3.2 char carbonaceous residue resulting from pyrolysis or incomplete combustion 4 Test apparat
41、us The apparatus specified in IEC 60332-1-1 shall be used. 5 Procedure 5.1 Sample 5.2 Conditioning Before testing, all test pieces shall be conditioned at (23 5) C for not less than 16 h at a relative humidity of (50 20) %. In the case of a single insulated conductor or cable with a finish of paint
42、or lacquer, this conditioning shall follow an initial period where the test piece shall be kept at a temperature of (60 2) C for 4 h. 5.3 Positioning of test piece ! “! “!“!“SOURCE: ISO 13943:2008, 1.489 SOURCE: ISO 13943:2008, 4.38 The test piece shall be straightened and secured to two horizontal
43、supports by means of a suitable size of copper wire, in a vertical position in the centre of the metal enclosure, as described in IEC 60332-1-1, so that the distance between the bottom of the upper support and the top of the lower support is (550 5) mm. In addition, the test piece shall be positione
44、d so that the bottom of the specimen is approximately 50 mm from the base of the enclosure (see Figure 1). The vertical axis of the test piece shall be arranged centrally within the enclosure (i.e. 150 mm from each side and 225 mm from the rear). The test sample shall be a piece of single insulated
45、conductor or cable (600 25) mm long. The test sample diameter shall be measured using the method given in IEC 60811-203. The measurement shall be made at each of three places, separated by at least 100 mm. The average of the three values obtained shall be rounded to obtain the overall diameter. If t
46、he calculation gives 5 or more for the second decimal figure, raise the first to the next number; thus, for example, 5,75 is rounded to 5,8. If the calculation gives 4 or less for the second decimal figure, maintain the first number; thus, for example, 5,74 is rounded to 5,7. The overall diameter ob
47、tained shall be used for the selection of the time for flame application.
