Overview
SIST EN 4708-204:2024 is a European standard developed by CEN for aerospace applications, specifically focusing on heat-shrinkable sleeving used for binding, insulation, and identification of electrical systems in aircraft. This standard defines the characteristics and performance requirements for limited fire hazard identification sleeves that operate reliably within a temperature range of -40 °C to 105 °C.
The sleeving is designed to offer enhanced safety in sensitive aircraft areas by being flame retardant and minimizing the emission of smoke, toxic gases, and corrosive by-products when exposed to fire. This makes it especially suitable for zones where smoke or corrosive emissions could pose critical hazards. The product is typically supplied with internal diameters up to 51 mm and a shrink ratio of 2:1, in standard white or yellow colors, with other sizes and colors available upon request.
Key Topics
- Material Properties: Flexible, flame-retarded sleeving that emits minimal smoke and toxic gases during a fire, reducing hazards in aircraft environments.
- Temperature Range: Operational from -40 °C to 105 °C, suitable for a broad range of aerospace electrical components and environments.
- Dimensions and Shrink Ratio: Standard internal diameters up to 51 mm with a shrink ratio of 2:1 to ensure tight and reliable fitting around cables.
- Testing and Compliance: Includes rigorous tests on dimensions, heat shock resistance, flame propagation, oxygen index, copper corrosion, smoke density, toxicity, halogen content, acid gas generation, and more to certify performance under aerospace standards.
- Print and Marking Permanence: Sleeving is a printed article evaluated for mark adherence and print permanence in line with EN 6059-407 using specified printers, ribbons, inks, and settings to ensure durable identification marks.
- Resistance to Fluids: Tested for resistance to aviation fuels, hydraulic fluids, oils, cleaning solvents, de-icing fluids, fire extinguishing agents, and avionic coolants to ensure durability in aircraft operational environments.
- Quality Assurance: Standards-compliant procedures aligned with EN 4708-001:2019 ensuring consistent product quality over its lifecycle.
Applications
- Aircraft Electrical Systems: Identification sleeves for wiring harnesses that require reliable insulation and clear marking under extreme conditions.
- Fire-Sensitive Zones: Areas within aircraft where smoke and toxic gas emissions during fire are critical hazards, such as passenger cabins, avionics compartments, and cargo holds.
- Maintenance and Inspection: Marked sleeves enable easy cable identification, facilitating maintenance, troubleshooting, and regulatory compliance in aerospace systems.
- Thermal Insulation: Heat-shrinkable nature provides protective insulation over cables and connectors, improving mechanical security and resistance to environmental stress.
- Corrosive Environment Protection: Minimizes corrosive by-products in case of fire, extending equipment life and ensuring safer emergency conditions onboard.
