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).
