BS 6387 IEC 60331 Cable Fire Resistance Tester with 950±40°C Flame Temperature and Automatic Operation for Mechanical Shock and Water Spray Test

Full standard fire test machine comprehensive GB, lEC and BS standards. The structure and performance of the combustion testmachine contains fire characteristics test, water and fire resistance test and mechanical vibration and fire resistance test. This instrument adopts computer software to control and monitor the test process of the current, voltage, gas flow, the test results ofthe curve can be output to print. lt is suitable for mineral insulated cables with rated votage not exceeding 0.6~1Kv, and can keep the circuit intact for a long timeunder flame conditions. In the national standard fire-resistant based on the addition of the British fire-resistant cable standard BS6387"in the case of fire to keep the circuit intact cable performance requirements specification".

1. BS Fire Resistance Test
1.1 Cable Support System
The cable is horizontally clamped onto one end of the cable sheaththrough a clamp. The middle part of the cable is fixed by two metal rings(spaced 300mm apart), which are grounded to the other metal parts ofthe device. For unarmoured cables with a diameter of less than 10 mmor for other cables that have shifted significantly during the test, threeadditional metal rings are required, each fixed at a distance ofapproximately 150 mm from the original ring.
1.2 Continuous Detection Device
During the test, the current is allowed to pass through all the cores of thecable, a three-phase star connected transformer with sufficient capacityto maintain the maximum allowable leakage current of 2A at the testvoltage. A load is connected to each core wire at the other end of thecable, and a current close to 0.25A is loaded at the rated voltage of thecable.
1.3 BS standard heat source: in line with AGF-1857B, nozzle length610mm burner
1.4 GB standard heat source: in line with AGF-1857B, nozzle length of500mm burners
1.5 Temperature measurement: 1.5 mm diameter armoured thermometerplaced near the air inlet, 75 mm above the burner, parallel to the burner.1.6 Test flame temperature: 950 + 40 °C
1.7 Specimen: The specimen is a section of the finished product, notless than 1200mm, with 100mm of sheath and covering removed at eachend. The wires at both ends of the cable shall be connected inaccordance with the electrical connection.
