Flame Test on Electrical and Optical Fiber Cable
The Vertical Flame Test to IEC 60332-1-2 is designed to assess the flame retardant properties on a single cable length.
ITC (ISO/IEC 17025 accredited) Testing laboratory Provide the flammability test on electrical and Optical fiber cable
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 1KW pre-mixed flame
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.
Tests on Electrical and Optical Fibre Cable under Fire Conditions
|Description||Tests for vertical flame propagation for a single insulated wire or cable – procedure for 1-kW pre-mixed flame|
|Length of specimen:||600 mm / 23.62 inches|
|Burner:||According to IEC 60332-1-1|
|Test temperature:||1 kW flame|
|Position of specimen:||vertical|
|Position of flame:||45° to vertical specimen|
|Duration of flame:||see table 1 (below)|
|Conditions:||Cable must be self-extinguishing. The damage or carbonization may only reach max. 50 mm under the upper fixing clamp.|
Table 1 (Time for flame application)
|Overall Diameter of test piece||Duration of the flame in second|
|D ≤ 25||60 ± 2|
|25 < D ≤ 50||120 ± 2|
|50 < D ≤ 75||240 ± 2|
|D > 75||480 ± 2|
This fire performance test is performed on a finished cable or the insulated single conductors, meaning all layers of the cable construction are subjected to the burner flame.
