The LS-B17 Insulating Sleeves of Plug Pins Abnormal Heat Resistance Test Device fully meets IEC 60884-1:2022 Clause 28.1.3 Figure 43 (GB/T 2099.1-2021 Clause 28.1.3 and Figure 40). Applicable to abnormal heat resistance and flame resistance test of plugs with insulating sleeves.

Test principle: Use a heating plate to heat the copper socket to simulate the situation where the plug and plug insulating sleeve is subjected to abnormal heat, so as to test its heat resistance.

Standard:
IEC 60884-1 (GB/T 2099.1) “Plugs and socket-outlets for household and similar purposes – Part 1: General requirements” Clause 28.1.3 Figure 43

Specification:
• Insulation plate: 5mm thick round flat surface, diameter is twice the diameter of the test piece contact surface, made of bakelite or epoxy board
• Metal part B (fixture): length greater than 20mm, made of brass, standard with GB6A two-pin, GB10A three-pin, GB16A three-pin, etc., can be customized
• Gap between insulation plate and metal part B: 3±0.2mm, to ensure air convection around the pins
• Thermocouple distance from the front of metal part B: 7±0.5mm
• Pin insertion hole on metal part B: larger than the maximum cross-sectional size of the pin by 0.1mm
• Equipped with K-type thermoelectric heater, imported high-precision digital temperature control meter
