Overview
EN 60684-3-248:2007 is a harmonized European standard from CENELEC (CLC), identical to IEC 60684-3-248:2007. It sets out requirements for six types of general-purpose, heat-shrinkable, dual wall polyolefin sleeving. This standard ensures flame retardance and covers products with nominal shrink ratios of 2:1, 3:1, and 4:1, available with low and high temperature adhesive inner walls. The standard is widely recognized in industries that demand high-performance electrical insulation, mechanical protection, and environmental sealing for wire and cable assemblies.
Key Topics
Scope of Application
EN 60684-3-248 covers sleeving types characterized by:- Shrink ratios of 2:1, 3:1, and 4:1
- Dual wall construction: flexible, cross-linked polyolefin outer layer and hot-melt adhesive inner wall
- Flame retardant properties
- Usability at temperatures up to 105 °C for low-temperature adhesive and up to 125 °C for high-temperature adhesive
Sleeving Types
- Type AL & AH: 2:1 shrink ratio (up to 51 mm), with low (AL) or high (AH) temperature adhesive
- Type BL & BH: 3:1 shrink ratio (up to 40 mm), with low (BL) or high (BH) temperature adhesive
- Type CL & CH: 4:1 shrink ratio (up to 52 mm), with low (CL) or high (CH) temperature adhesive
General Requirements
- Color: Standard issue in black, with custom colors and sizes available subject to property requirements
- Adherence to dimensional, physical, and electrical property criteria as specified within the standard
Testing and Performance
- Heat shock, elongation, tensile strength, and flame propagation
- Breakdown voltage requirements linked to wall thickness
- Resistance to fluids, environmental exposures, and color fastness
- Specialized tests for dimensional stability and elevated temperature performance
Applications
EN 60684-3-248:2007 is key in sectors requiring reliable electrical insulation and robust environmental protection, including:
Electrical and Electronics Manufacturing
- Protecting wire splices, connections, and terminals
- Bundling and insulating cable harnesses
Automotive and Aerospace
- Sealing and environmental protection for cable assemblies exposed to vibration, fluid ingress, or temperature extremes
Industrial and Energy
- Insulating and reinforcing busbars, transformers, and switchgear
- Mechanical strain relief and abrasion protection for cables and wiring in demanding installations
Maintenance and Repair
- Retrofitting older systems with heat-shrink tubing for improved safety and reliability
- Quick repairs to damaged insulation in the field
By specifying requirements for general-purpose, heat-shrinkable, flame-retardant dual wall polyolefin sleeving, the standard enhances the safety, performance, and longevity of electrical installations across diverse environments.
