Glow wire tester
F242 Glow-wire tester, By simulating the thermal stress caused by heat source or ignition source such as hot component or overload resistor in a short period of time, so as to test the flammability and ignitability of circuit component, which is widely used in electronic and electrical, household appliances, household and industrial lighting, electrical insulation materials and so on. And, it can predict the safety during use of circuits, effectively control production and verify product performance.
1.During the use of electrical materials, it may reach excessive temperature and cause fire hazard due to overload, short circuit, poor electrical contact or other fault conditions. The glowing-wire test refers to a simulated an overloaded resistance heat source to apply thermal stress to the sample in a short period of time. The fire risk of the sample is assessed by observing the light-off state of the sample and measuring relevant indicators.
2.After the heating wire of the specified material and shape is heated to the test temperature (550C - 960C) with a large current by the glow-wire test device, so as to confirm that the temperature does not fluctuate obviously within 60 seconds, and the test piece is burned vertically for 30 s at a specified pressure (1.0 N). Measure the ignition hazard of the finished electrical and electronic equipment according to whether the test materials and the mats are light-off or holding time.lt can measure the light-off property, light-off temperature, flammability and flammability index of solid insulating materials and other solid combustible materials.
