Scope: glow-wire test apparatus for lighting, low voltage electrical equipment, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instruments, IT equipment, electrical business equipment, electrical connectors and accessories and other electrical and electronic products their research, production and quality control departments component parts, but also for insulation, plastic or other solid combustible materials industry;

Standard: glow-wire test is IEC60695-2-10: 2000 ~ IEC60695-2-13: 2000 "Glowing / hot, the basic test methods, glow-wire test apparatus and common test procedure" and GB4706.1 and GB / T5169, standard UL746A, IEC829, DIN695, VDE0471 such as the use of non-flame ignition source simulation project;

Rationale: glow-wire test apparatus will provide material (Ø4 Ni80 / Cr20) and the shape of the electric wire with a large current is heated to the test temperature (550 ℃ ~ 960 ℃) 1min after a predetermined pressure (1.0N) vertical scalding test 30s, depending on whether the test product and bedding ignition or time to determine who fired the finished electrical and electronic equipment fire risk; Determination of solid insulating materials and other solid combustible materials from flammable, ignition temperature (GWIT), flammability and Flammability index (GWFI);

Main features: glow-wire test instrument using the chamber portion and the control portion integrated design, easy on-site installation and commissioning. Chamber shell and an important component of stainless steel, anti-smoke, gas corrosion; using energy-efficient regulator manually adjust the test current, achieve precise temperature control purposes; time, temperature digital display, easy to observe and record, the use of stable and reliable.
