What is BS EN 4708-108 - Fire hazard sleeving about ? BS EN 4708-108 is an international standard for aerospace series that guides on the fire hazard sleeving. BS EN 4708-108 specifies the required characteristics for four types of heat-shrinkable limited fire hazard sleeving for use in aircraft electrical systems at operating temperatures between 65 °C and 150 °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: Medium wall, shrink ratio 2:1 and is normally supplied with internal diameters up to 30 mm.
