What is BS EN 4840-101 - Heat shrinkable moulded shapes about ?
BS EN 4840-101 is a European Standard that specifies the required characteristics for heat-shrinkable polyolefin semi-rigid, limited fire hazard heat-shrinkable boots for use in aircraft electrical systems at operating temperatures between − 30 °C and 105 °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.
These moulded shapes are normally supplied in the styles and dimensions given in EN 4840‑002 Tables 1 to 22. The colour is normally black.
Styles and dimensions other than those specifically listed in EN 4840‑002 Tables 1 to 22 may be available as custom items. These items shall be considered to comply with this standard if they comply with the property requirements listed in Table 1 with the exception of dimensions.

Why should you use BS EN 4840-101 - Heat shrinkable moulded shapes ?
BS EN 4840-101 provides you guidance on requirements which includes dimensions and mass, conditions of the test, conditions of the test, moulded shape material conformance, moulded shapes compatibility and resistance to fluids which enables you to perform the method correctly, which increases accuracy and consistency in development and assessment for the moulded shapes.
BS EN 4840-101 is beneficial as they are used in electrical applications to insulate high voltage current from surrounding areas which deals with flexible insulating sleeving for electrical purposes.
BS EN 4840‑101 provides you guidance on dimensions, density, heat shock, tensile strength, elongation at break, bending at low temperature and dimensional stability during storage which enhances the mechanical toughness of moulded shapes.
