Overview
IEC 60684-3-116:2010 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the requirements for flexible insulating sleeving made from extruded polychloroprene elastomer. This standard focuses on non-heat-shrinkable sleeving designed for general-purpose electrical insulation applications, suitable for use at temperatures up to 95 °C. It applies to sleeving typically available with internal diameters up to 25 mm and offered in a variety of opaque colours including black, brown, red, orange, yellow, green, blue, violet, grey, white, and pink. Custom sizes and colours beyond those listed may also be available while still maintaining conformity with the essential performance criteria.
This third edition of the standard updates previous versions by including new testing requirements such as tear propagation, circumferential extension, voltage proof, and thermal shock to ensure enhanced durability and safety.
Key Topics
- Material and Design: Polychloroprene elastomer extruded sleeving for electrical insulation, non-heat-shrinkable.
- Temperature Rating: Suitable for continuous operation up to 95 °C.
- Dimensions: Internal diameters range from small sizes up to 25 mm with defined wall thicknesses categorized as thin or thick walls.
- Colour Options: Standard opaque colours per IEC 60757 code plus custom colours available.
- Testing and Performance Requirements:
- Dimensional Compliance: Strict dimensional tolerances for diameter and wall thickness.
- Mechanical Tests: Bending at high and low temperatures, tension, tear propagation, and circumferential extension to prevent cracking or splitting.
- Electrical Tests: Voltage breakdown and voltage proof tests to certify electrical insulation reliability.
- Environmental and Chemical Resistance: Heat aging, ozone resistance, flame propagation, silver staining, and colour fastness to light ensure durability in varied conditions.
- Additional Tests: Thermal shock resistance and verification that sleeving does not slip off mandrels under own weight.
Applications
IEC 60684-3-116 polychloroprene insulating sleeving is highly versatile and used in multiple electrical and electronic applications, including:
- Wire and Cable Protection: Insulating and protecting electrical wiring in industrial machinery, automotive, and household appliances.
- Harness Assemblies: Keeping wire bundles grouped and shielded from mechanical damage and environmental exposure.
- Electrical Equipment Manufacturing: Component insulation in motors, transformers, connectors, and switchgear.
- Maintenance and Repair: Replacement sleeving providing robust insulation and sealing for refurbishment.
- Custom Industrial Solutions: Offered in a wide range of colours and sizes for identification and specific engineering requirements.
The standard ensures that the sleeving used meets essential safety, durability, and functional performance benchmarks making it suitable for electrical insulation needs in environments where moderate temperatures and mechanical stresses are common.
