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

Glow wire tester is suitable for lighting equipment, low-voltage electrical appliances, electrical instruments, and other electrical and electronic products and non-metallic materials and parts for household electrical appliances, such as: switch shell, relay socket. Wide range of applications. It can be applied to the production enterprises, quality inspection departments, institutions and research institutes and other institutions.

Instruction

The best method for testing electro technical products with regard to fire hazard is to duplicate exactly the conditions occurring in practice. In most instances, this is not possible. Accordingly, for practical reasons, the testing of l products with regard to fire hazard is best conducted by simulating as closely as possible the actual effects occurring in practice.

Parts of insulating material or other material which are liable to propagate flames inside the equipment may be ignited by glowing wires or glowing elements.

Under certain conditions (for example, a fault current flowing through a wire, overloading of components, and bad connections), certain elements may attain a temperature such that they will ignite parts in their vicinity.
