Apparatus for Testing Resistance to Abnormal Heat of Insulating Sleeves
1. Introduction
Apparatus for testing resistance to abnormal heat of insulating sleeves is designed according to IEC6884-1 figure 40, it is applied to test heat and flame resistance performance of insulating sleeves
2. Parameter
Insulating plate | 5mm thickness, flat surface Made by Bakelite or epoxy board diameter twice the maximum permissible dimension of the engagement face of the plug |
Metal part B | Length ＞ 20mm Material: brass Equip with 6A 2-pins, 10A 3-pins, 16A 3-pins |
Gap between insulating plate and metal part B | 3±0.2mm, ensure air convection around the pins |
Distance between thermocouple and positive side of metal part B | 7±0.5mm |
Thermocouple | K type, with digital temperature meter |
