The bunched cable combustion tester is mainly used to detect the ability of vertically installed bunched cables or fiber optic cables to inhibit the vertical spread of flame under specified conditions. The equipment is widely used in power cables, control cables, fiber optic cables and other bunched combustion test, is the wire and cable industry quality control and ensure product safety performance of an important tool.
I. Main Functions
1. Flame retardant performance test: Evaluate the flame retardant performance of bunched cables under flame conditions and determine their ability to inhibit flame spread.
2. Simulation of fire scenarios: Simulate actual fire scenarios by accurately controlling the flame temperature and burning time to test the flame retardancy of cables34.
3. Data recording and analysis: Record indicators such as the speed of fire spreading and self-extinguishing time of the cable to judge its flame retardant level4. 4.
4. Safe design: Equipped with an emission purification system to ensure that the exhaust gas generated during the test is initially purified and treated to prevent pollution of the environment.
Second, the test steps
1. Start the equipment: turn on the power, start the test program, and confirm that all indicators show normal.
2. light the flame: open the gas device, adjust the flow rate to the appropriate value, light the blowtorch and adjust the flame.
3. Start the test: Aim the blowtorch at the specimen, start the combustion test, observe and record the combustion of the specimen.
4. Monitor and record: pay close attention to the operating status of the equipment and the combustion of the specimen, and stop the test immediately if there is any abnormality 6.
III. Post-test treatment
1. extinguish the flame: after the test, extinguish the blowtorch in time, turn off the gas device and power supply7. 2.
2. Handle the specimen: remove the specimen for cleaning and inspection, and assess the degree of damage7.
3. writing a report: write a test report based on the test data and observations7.
Analysis of test results
1. Burning time: Record the flamed burning time and flameless burning time to analyze the flame retardancy of the specimen.
2. Burning length: Measure the distance of flame propagation along the surface of the specimen to evaluate the flame spreading speed.
3. Drops: Observe whether there are burning drops and their burning condition during the test.
4. flame spread: observe the flame spread speed and direction on the specimen.
5. Afterflame and afterburning: Record the duration of afterflame and afterburning after the specimen has withdrawn from the flame.
6. Charring Height: Measure the height reached by the charred portion of the specimen, compare it with the standard, and determine whether it passes or fails.
