Flammability Testing Equipment For Vertical Flame Propagation For Single Insulated Cable
Standard:
IEC 60332-1-1 Tests on electric and optical fibre cables under fire conditions –Part 1-1: Test for vertical flame propagation for a single insulated wire or cable – Apparatus;
IEC 60332-1-2 Tests on electric and optical fibre cables under fire conditions –Part 1-2: Test for vertical flame propagation for a single insulated wire or cable – Procedure for 1 kW pre-mixed flame;
IEC 60332-1-3 Tests on electric and optical fibre cables under fire conditions –Part 1-3: Test for vertical flame propagation for a single insulated wire or cable – Procedure for determination of flaming droplets/particles.
Application:
It is use for testing the resistance to vertical flame propagation for a single vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions. Flammability Testing Equipment
Positioning of test piece:
The test piece shall straightened and be 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 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 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 piece shall be arranged centrally within the screen (i.e. 150 mm from each side and 225 mm from the rear).
