23、ire or cable Procedure for determination of flaming droplets/particles 1 Scope This part of IEC 60332 specifies a test procedure for assessment of falling flaming droplets/ particles when a single vertical electrical insulated conductor or cable, or optical fibre cable, is subjected to defined fire

24、conditions. NOTE 1 Testing to IEC 60332-1-3 may be performed simultaneously with that to IEC 60332-1-2, if required. Recommended requirements for performance are given in Annex A. IEC 60332-1-3 specifies the use of a 1 kW pre-mixed flame and is for general use, except that the procedure specified ma

31、ilter paper shall consist of undyed cellulose filter paper of a density of (80 15) g/m 2with an ash content of less than 0,1 %. The filter paper shall be conditioned in accordance with ISO 187. 5 Procedure 5.1 Sample The test sample shall be a piece of insulated conductor or cable (600 25) mm long.

32、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 an insulated conductor or cable with a finish of paint or lacquer, this conditioning shall follow an initial period where the test piece shall

33、be kept at a temperature of (60 2) C for 4 h. 5.3 Positioning of test piece and filter paper The test piece shall be straightened and secured to two horizontal supports by means of a suitable size of copper wire, in a vertical position in the centre of the metal screen, as described in 4.2 of IEC 60

34、332-1-1, 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 positioned so that the bottom of the specimen is approximately 50 mm from the base of the screen (see Figure 1). The vertical axis of the test pi

35、ece shall be arranged centrally within the screen (i.e. 150 mm from each side and 225 mm from the rear). Two pieces of filter paper (300 10 300 10) mm shall be placed flat, one on top of the other, on the base of the metallic screen, no more than 3 min before the start of the test. The filter papers

36、 shall be positioned centrally beneath the test piece.

37、hen conducting tests: a) the risk of fire or explosion; b) the inhalation of smoke and/or noxious products, particularly when halogenated materials are burned; c) harmful residues. 5.4.1 Positioning of flame One calibrated burner, as described in 4.3 of IEC 60332-1-1, shall be ignited and the recomm

38、ended flow rates of gas and air adjusted. The burner shall be positioned so that the tip of the inner blue cone impinges on the surface of the test piece at a distance of (475 5) mm from the lower edge of the upper horizontal support, whilst the burner is at an angle of 45 2 to the vertical axis of

39、the test piece (see Figure 2). For flat-form cables, the flame impingement shall be on the middle of the flat side of the cable. 5.4.2 Test duration The flame shall be applied continuously for the period of time corresponding to the diameter shown in Table 1.

41、lat cables having a ratio of major to minor axis greater than 17:1, the flame application time remains under consideration. At the end of the specified test duration, the burner shall be removed and the flame of the burner extinguished. 6 Evaluation of test results During the test duration, it shall

42、 be recorded: a) if the filter paper has ignited or not; b) if the filter paper has ignited, the time from ignition of the filter paper to cessation of the burning.
