What is BS EN 4708-106 - Fire hazard sleeving about ?
BS EN 4708-106 is a European Standard that specifies the required characteristics for four types of heat-shrinkable limited fire hazard sleeving for use in aircraft electrical systems at operating temperatures between – 30 °C and 105 °C.
This sleeving is flexible, flame retarded and emits minimum smoke, gases and corrosive by-products when exposed to fire. It is available with various wall thicknesses and, also in a higher shrink ratio according to the application and degree of mechanical protection required. It is suitable for use (e.g., as cable protection) in areas where smoke, gases or corrosive by-products would constitute a particular hazard.
- Type A: Thick wall shrink ratio 2:1 and is normally supplied with internal diameters up to 102,0 mm
- Type B: Medium wall, shrink ratio 2:1 and is normally supplied with internal diameters up to 60,0 mm
- Type C: Thick wall, shrink ratio 2:1 and is normally supplied with internal diameters up to 51,0 mm
- Type D: Medium wall, shrink ratio 3:1 and normally supplied with internal diameters up to 40,0 mm
The standard colour of these sleevings is black.
Sizes or colours other than those specifically listed in BS EN 4708-106 may be available. These items shall be considered to comply with BS EN 4708-106 if they comply with the property requirements listed in Tables 5, 6 and 7 except for dimensions and mass.

Why should you use BS EN 4708-106 - Fire hazard sleeving ?
BS EN 4708-106 covers about four types that are available as custom items which have been mentioned in a detailed form including their sizes and colour.
A fire sleeve is a protective covering wrapped around flexible hoses to protect from fire.
Fire sleeves are easy to apply, halogen-free, flame retardant, self-extinguishing, print compatible, and emit minimum smoke during a fire and are ideal to use where limited fire hazard properties are required. BS EN 4708-106 guides you through all these characteristics.
A fire sleeve is specially designed to protect cables and hoses exposed to high temperatures and molten metal splashes.
By using BS EN 4708-106, you can manufacture the best quality fire sleeves including all the qualities that make it best for use in aircraft.
