Glow wire test machine 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.

Brief Introduction

The glow wire tester operation instructions according to the GB5169 and GB4706 the design and manufacturing requirements with the standards so called glow wire test method, which apply to the fire danger test on electrical and electronic products, household electrical appliances and materials, simulation heat element or overload resistance of heat or ignition source caused by thermal stress in a short time.
