General Information
Overview
SIST EN 4840-102:2020 is a European standard developed by CEN specifying the requirements for heat shrinkable elastomeric semi-rigid moulded shapes intended for aerospace applications. These heat-shrinkable boots are designed for use within aircraft electrical systems, providing reliable insulation and protection across an operating temperature range from -75 °C to 150 °C. The standard ensures standardized dimensions, material properties, and performance criteria for these specialized components.
The moulded shapes may be supplied with or without pre-coated adhesives, and guidance on adhesive compatibility is provided. Typically these components are black and comply with specified styles and dimensions referenced in EN 4840-002. Custom dimensions are also possible provided the material properties conform to the specified requirements.
Key Topics
Material Characteristics
The standard defines physical, mechanical, electrical, and thermal properties of the heat shrinkable elastomeric semi-rigid boot materials. These include tensile strength, elongation at break, secant modulus, dimensional stability, electric strength, volume resistivity, and resistance to heat shock.Temperature Range
Designed to function effectively in extreme temperature conditions ranging from -75 °C to 150 °C, enabling applications in harsh aerospace environments.Testing Requirements
The standard mandates rigorous testing protocols such as heat shock resistance, low-temperature bending without cracking, long-term aging, copper corrosion, fluid resistance, and compatibility with adhesives. Tests simulate operational stresses to ensure reliability and safety.Adhesive Compatibility
A key aspect includes compatibility with various adhesive types (R, S, U, W1, W2, Z) to guarantee bonding performance. Annex A offers an informative guide to selecting suitable adhesive types based on temperature range and sleeve compatibility.Dimensions and Variants
Components are available in standardized styles and sizes as per EN 4840-002 tables, with the option for custom sizes adhering to all property requirements aside from dimension.Quality Assurance and Labelling
Quality assurance follows EN 4840-001 guidelines, detailing packaging, labelling, and designation methods to assure traceability, compliance, and easy identification within aerospace supply chains.
Applications
Aircraft Electrical Systems
The primary application is in protective insulation of aircraft electrical wiring and connectors. These moulded boots ensure electrical safety by providing environmental and mechanical protection.Harsh Aerospace Environments
Due to their wide temperature tolerance, the heat shrinkable elastomeric boots are ideal for use in aerospace environments exposed to thermal cycling, mechanical vibrations, and fluid exposures such as fuels and hydraulic oils.Custom Aerospace Components
Manufacturers can produce custom-shaped, bespoke boots conforming to aircraft-specific requirements for electrical harness protection, cable sealing, and strain relief applications.
