TESTS ON ELECTRIC AND OPTICAL FIBRE CABLES

UNDER FIRE CONDITIONS –

Part 2-1: Test for vertical flame propagation for a single small insulated wire or cable –

Apparatus

1 Scope

This part 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 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 amendments) applies

3 Terms and definitions

For the purposes of this document, the following definition applies 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 chamber (4.4)

Page 4

EN 60332−2−1:2004

-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 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 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 facilities 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 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 door 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
