  • 产品名称: GLOW WIRE TESTER
  • NO.: GW-2
  • Views : 55

Standard: IEC60695-2-10, IEC60695-2-13, UL746A and etc.

Application: It is applicable for electric and electronic products, household appliances and other material’s fire hazard testing. It is also used in the No flame ignition source fire test to test initiation temperature and flammability index of related glowing filament.


Purpose: This device simulates the effect of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors for short periods, in order to access the fire hazard by simulation technique.

Test Sample Range: Electrotechnical equipment, electrotechnical equipment’s subassemblies and components, solid electrical insulating materials, other solid combustible materials.

Structure & Function: The test machine is adopting advanced PLC control and with 7 inch color touch screen display, it has a solenoid valve switch to control the burning depth of test sample and equipped with measuring gauge, the test will be exact and rapid. The test sample will break away automatically from glowing filament after reaching the set time. It is equipped the original imported UK LAB K type armour(1mm)which temperature resistance is up to 1100°(exceed 1050°of standard requirement), the temperature control is accurate.
