IEC 60884-1 Figure 40 Insulating Sleeves of Plug Pins Abnormal Heat
Resistance Test Apparatus
Product information:
This device meets the standards of IEC 60884-1:2013 clause 28.1.2
figure 40. It is applicable to test improper heating resistance and
burning resistance of bolt and plug with insulation sleeve. It can
imitate the insulated parts of which the plug-and-socket device’s
safety performance may be damaged by electric heat stress. It
should not be over damaged for exposure to overheating and under
fire.
Technical parameters:
Power supply: match client's local power grid requirements.
Insulation board: 5 mm thickness round flat surface, the diameter
of the two times as test product surface' diameter.
Metal parts B (Fixture): the length is more than 20 mm, brass, can
be replaced; should be designed according to different countries'
standards.
Gap between insulation board and metal parts B: 3 mm, ensuring
surrounding cross-ventilation.
Distance between thermocouple and the metal parts B: 7 mm.
Bolt hole of Metal parts B: more than 0.1 mm.
Equipped with K-type electric heater, imported high-precision
digital-display table.

Fixture Installation:
1. Select the corresponding brass Metal parts B and insulation
board according to the specimen, pay attention to the zero mark of
the test seat is paralleled the mark bit of the heating base when
installation.
2. The thermocouple is installed in the threaded hole of the Metal
parts B.
Timing and temperature presets:
1. Preset the time and temperature as the required value refer to
instrument setting method.
2. Press "START" button, the test apparatus is heated, it can be
maintained in the preset temperature range about 30 min.
Test Operation:
1. Insert the specimen into the brass Metal parts B after
confirming the test temperature is stable, at the same time, press
the reset time to start timing, the test apparatus will stop
heating automatically when the testing time is up.
2. Remove the specimen and inspect according to related standard
requirements.
