IEC 60884 Plug Pin Insulation Sleeve Abnormal Heat Resistance Test Apparatus for Plug Socket Compliance Testing

Imagine a household plug operating for years.

One day, due to poor contact, overload conditions, or abnormal heat accumulation, the temperature around the plug pin begins to rise.

The question is:

Will the insulation sleeve continue to protect users?

Or will it deform, crack, or lose its protective function?

This is exactly why IEC 60884 requires abnormal heat resistance testing for insulated plug pins. Manufacturers must prove that their products remain safe even when exposed to elevated temperatures.

The HongCe HC9935 Plug Pin Insulation Sleeve Abnormal Heat Resistance Test Apparatus is specifically designed for evaluating the resistance of insulating sleeves on plug pins against abnormal heat and fire-related thermal stress according to IEC requirements.

Developed by HongCe's engineering team and manufactured in our own factory, the HC9935 helps laboratories and manufacturers confidently verify compliance before certification testing.

The HC9935 recreates the thermal conditions specified in IEC 60884 Figure 40.

During testing:

• Plug pins are inserted into a precision brass fixture
• Controlled heating is applied
• Temperature is monitored by a K-type thermocouple
• Insulating sleeves are evaluated for resistance to abnormal heat exposure
• Results determine whether the insulation remains compliant under extreme conditions

Unlike trading companies, HongCe designs and manufactures testing equipment internally.

This means:

• Faster delivery
• Better customization capability
• Stable spare parts supply
• Direct engineering support
• Competitive pricing
