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
Scope
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
| Standard | IEC 60332-1-2 |
| 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.
