F242 Glow-wire tester simulates thermal stress from heat sources to test circuit component flammability, widely used in electronics, appliances, etc. It predicts circuit safety, controls production, and verifies performance. The test applies short-term heat to samples, assessing fire risk by observing light-off states. It measures ignition hazards of materials by burning them at specified temps and pressures.
Application
It is used in the evaluation of flammability tests and light-off temperature tests for electrical equipment and its components and accessories, as well as solid electrical insulating materials or other solid flammable materials.
It is used for the test of ignition hazard of electronic and electrical products, the evaluation of hot burning performance and the test of high temperature resistance.
It is used to determine the light-off property, light-off temperature, flammability and flammability index of solid insulating materials and other solid combustible materials.
It is used to test flame retardant properties for the insulated enclosure of household appliances, switch panels, printed circuit boards,and insulating materials.
It is applicable to the performance verification of new products, quality control of the production department, and the of material properties for the third-party testing organization, the product performance verification laboratory, and the quality and technical supervisiondepartment, etc.
