BS EN IEC 60684 is an international standard that discusses flexible insulating sleeving for electrical purposes. The main objective of the BS EN IEC 60684 series is to ensure that the insulating sleeving manufactured offers required level of electrical resistance.
BS EN IEC 60684-3-247 gives requirements for two types of heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded with a nominal shrink ratio of 3:1.
This sleeving has been found suitable for use at temperatures of up to 100 °C.
These sleevings are normally supplied in colour black.
BS EN IEC 60684-3-247 on flexible insulating sleeving is relevant to:
Heat-shrinkable polyolefin sleeving is critical to electrical applications as it offers excellent insulation and acts as a corrosion-resistance protective layer.
Since these types of sleeving cover a significantly large range of sizes and wall thicknesses, BS EN IEC 60684-3-247 provides guidance on the range of sizes available.
BS EN IEC 60684-3-247 also covers property requirements, requirements for dielectric strength and breakdown voltage, and standard references for test methods to establish conformity of the same.
Complying with BS EN IEC 60684-3-247 requirements can ensure the heat-shrinking polyolefin sleeving provides excellent electrical insulation and incidents of splitting and product failure, are minimized. If you are a manufacturer of polyolefin sleeving, adopting standardized practices can enhance reliability and credibility of your products.
