The purpose and main parameters of the hot wire tester are designed and manufactured according to IEC60695-2-10 and GB5169.12 standards. It is a comprehensive testing equipment that can simultaneously meet the requirements of relevant standards. It is mainly used to simulate the thermal stress caused by heat sources or ignition sources such as hot elements or overload resistors in a short period of time. It is suitable for conducting fire hazard tests on electrical and electronic products, household appliances and their materials, as well as for flameless ignition source ignition tests to determine the ignition temperature, flammability and flame resistance index of the hot wire of related materials.

Application and main parameters of the hot wire tester:

Within 30 seconds after removing the hot wire, the flame or heat of the test sample shall extinguish, and the packaging paper placed under the test sample shall not ignite, and the test sample shall not ignite.

2. Test sample: length ≥ 60mm, width (measured inside the fixture): ≥ 60mm, selected thickness: 0.75mm ± 0.1mm, 1.5mm ± 0.1mm, or 3.0mm ± 0.2mm

3. Experiment: Contact the sample for 30s ± 1s and approach and leave the sample at a speed of approximately 10mm/s to 25mm/s.

4. Pressure: 1.05N, depth 7mm ± 0.5mm

5. Armored thermocouple 1mm,

6. U-shaped head 4mm

Application and main parameters of the hot wire tester:

1. Burner: minimum length35mm、 A pipe with an aperture of 0.5 ± 0.1mm and an outer diameter not exceeding 0.9mm.

2. The purity of butane or propane gas shall not be lower than95%）

3. Flame: Flame heightThe test time for raising the temperature from 100 ℃± 5 ℃ to 700 ℃± 3 ℃ from 12mm ± 1mm should be 23.5s ± 1.0s.
