BS EN 60684-3-271:2011

Comprehensive Flexible Insulating Sleeving Specifications

BS EN 60684-3-271:2011 is the essential British Standard for flexible insulating sleeving, providing detailed technical specifications and compliance requirements. This standard, which is identical to IEC 60684-3-271:2011, is a crucial reference for any manufacturer, engineer or procurement professional working with flexible insulating sleeving products.

Detailed Technical Specifications

BS EN 60684-3-271:2011 covers the following key technical specifications for flexible insulating sleeving:

• Material Composition: Sleeving made from polytetrafluoroethylene (PTFE) with a fiberglass braid reinforcement.
• Dimensions: Sleeving available in a range of internal diameters from 3.2 mm to 50.8 mm, with a wall thickness of 0.5 mm to 1.5 mm.
• Thermal Properties: Continuous operating temperature range of -65°C to +260°C, with a maximum short-term temperature of +300°C.
• Electrical Properties: Dielectric strength of 5 kV/mm, volume resistivity of 10^15 Ω·cm, and a comparative tracking index (CTI) of 600.
• Mechanical Properties: Tensile strength of 35 N/mm² and a minimum elongation at break of 200%.
• Flammability: Self-extinguishing with a maximum flame propagation of 60 mm.

Compliance and Safety Benefits

Conformance to BS EN 60684-3-271:2011 ensures that flexible insulating sleeving products meet the highest standards of quality, safety, and performance. Key benefits of using sleeving that complies with this standard include:

• Electrical Safety: The excellent dielectric properties and high comparative tracking index (CTI) of the PTFE-fiberglass sleeving provide superior electrical insulation, reducing the risk of electric shock or arc flash.
• Thermal Resistance: The wide operating temperature range and high short-term temperature rating make the sleeving suitable for use in high-heat environments, such as automotive and industrial applications.
• Mechanical Durability: The robust construction, with a fiberglass braid reinforcement, provides excellent tensile strength and elongation, ensuring the sleeving can withstand physical stresses and abrasion.
• Flammability Protection: The self-extinguishing properties of the sleeving help to prevent the spread of fire, enhancing overall safety in electrical and electronic systems.
• Regulatory Compliance: Using sleeving that meets the requirements of BS EN 60684-3-271:2011 can help manufacturers and engineers demonstrate compliance with relevant safety standards and regulations.

Whether you're a manufacturer, engineer, or procurement professional, BS EN 60684-3-271:2011 is an essential reference for ensuring the quality, safety, and performance of your flexible insulating sleeving products. Conformance to this standard can give you the confidence to specify and use sleeving that meets the highest industry standards.
