This European Standard specifies the required characteristics for heat-shrinkable elastomeric semi-rigid, boots for use in aircraft electrical systems at operating temperatures between -75 °C and 150 ° C. The moulded shapes may be supplied with a pre-coated adhesive. Refer to the manufacturers/suppliers for options. A guide to adhesive compatibility is given in Annex A (informative). These moulded shapes are normally supplied in the styles and dimensions given in EN 4840-002 Table 1 to Table 22....view more

This standard specifies the required characteristics for a heat-shrinkable, polytetrafluoroethylene sleeving for use in aircraft electrical systems at operating temperatures between ? 65 °C and 260 °C. This sleeving is basically translucent. It is semi-rigid, and suitable for use where resistance to chemicals and high temperature performance are required. It is flame resistant and available in low and high shrink ratios. Type A Low Shrink Ratio; Type B High Shrink Ratio .

This standard specifies the required characteristics for four types of heat-shrinkable limited fire hazard sleevings 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...view more

This document specifies the required characteristics for a heat-shrinkable, semi-flexible polyvinylidene sleeving for use in aircraft electrical systems at operating temperatures between − 55 °C and 150 °C. This sleeving is basically transparent, but may be tinted. It is semi-flexible tough and abrasion resistant, and is suitable for use where strain relief and mechanical protection are required, or where their transparent properties are desirable. It is not suitable for use where contamination ...view more
