What is BS EN 4840‑102-Aerospace series: Heat shrinkable moulded shapes about?
BS EN 4840‑102 is a standard that serves technical specifications for aerospace series: Heat shrinkable moulded shapes, which enables electrical insulation and superior chemical and environmental resistance.
BS EN 4840‑102 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, depending on manufacturers/suppliers.
BS EN 4840‑102 specifies a guide to adhesive compatibility, which is given in Annex A. Moulded shapes are normally supplied in the styles and dimensions given in EN 4840-002 Table 1 to Table 22. The colour is normally black.
Styles and dimensions other than those specifically listed in EN 4840-002 Table 1 to Table 22 may be available as custom items. These items shall be considered to comply with BS EN 4840‑102 if they comply with the property requirements listed in Table 1 except for dimensions.
Who is BS EN 4840‑102-Aerospace series: Heat shrinkable moulded shapes for?
BS EN 4840‑102 on aerospace series: Heat shrinkable moulded shapes applies to:
- Manufacturers of moulded shapes for aerospace applications
- Dealers and importers of moulded shapes for aerospace applications
- Testing houses and labs for moulded shapes for aerospace applications
- Safety and quality assurance services in aerospace industry
- Regulatory bodies and disaster management services in aerospace industry
Why should you use BS EN 4840‑102-Aerospace series: Heat shrinkable moulded shapes?
Heat shrinkable moulded shapes are generally used for electrical and electronic harnessing applications. They have functional and cost-saving features in electrical and electronic applications by providing electrical insulation and protection against abrasion.
BS EN 4840‑102 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 do the method correctly, which increases accuracy and consistency in development and assessment for the moulded shapes.
BS EN 4840‑102 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.
BS EN 4840‑102 also provides you guidance on electric strength, volume resistivity, flammability, copper corrosion, colour fastness to light, resistance to selected fluids, mass, heat ageing, water absorption that enhances the electrical strength and enables you to ensure the safety of aerospace systems.
Guidance in BS EN 4840‑102 enables you to develop and assess heat-shrinkable moulded shapes that enhance electrical insulation in electrical and electronic systems in the aerospace industry.
