IEC 60331, BS 6387 Electric Cables Under Fire Conditions Circuit integrity Testing Machine EN 50200
- Fire-resistant cable refers to the cable that can keep a safe running time in the case of flame combustion. Fire Resistance Tester is designed according to the requirements of IEC60331-11, and used to obtain the refractory characteristics of a fire resistant cable or optical cable under flame conditions.
- It is applicable to cables of rated voltage not exceeding 600V/ 1000V, including those of rated voltage below 80 V, matallic data and telecom cables and optical fibre cables.
- It is intended for use when testing cables of greater than 20mm overall diameter.
