Overview
SIST EN 4840-001:2018 is a European standard developed by CEN under the Aerospace and Defence Industries Association of Europe (ASD-STAN). It specifies the technical requirements, test methods, and quality assurance procedures for heat shrinkable moulded shapes used primarily in aerospace applications. This standard ensures that heat shrinkable components meet consistent performance, durability, and safety criteria essential for aerospace industries across Europe and beyond.
This document complements related product standards (such as EN 4840-002), providing a comprehensive framework for manufacturers and users in the aerospace sector regarding the production, testing, and storage of heat shrinkable moulded shapes.
Key Topics
Materials and Characteristics
Heat shrinkable moulded shapes must be fabricated from materials that comply with product-specific standards, ensuring desired physical and chemical properties. The finished products must be free of defects such as bubbles, pinholes, or creases that could impact functionality. Dimensions and temperature performance parameters are defined in related product standards like EN 4840-002.Required Properties and Test Methods
EN 4840-001 outlines the prescribed test methods for assessing essential properties including mechanical strength, dimensional stability, electric strength, and resistance to heat and environmental conditions. Testing aligns with IEC 62329-2 standards and incorporates rigorous qualification, routine, and periodic assessments to sustain product quality.Quality Assurance and Qualification
The standard stipulates a detailed quality management approach based on EN 9133, requiring qualification of materials and moulded shapes through defined testing protocols. Maintenance of qualification involves repeat tests every 60 months or after production interruptions longer than 36 months, ensuring continuous compliance.Labelling and Packaging
Proper labelling is mandatory for traceability, including manufacturer name, product designation, batch number, date of manufacture, use-by date, and quantity. Packaging must protect the products from damage during transport and storage, with recommendations to preserve product integrity.Storage Recommendations
Annex A provides guidance to prevent dimensional changes during storage, such as maintaining temperatures between 18 °C and 26 °C, avoiding sunlight exposure, storing in dry conditions, and proper resealing of partially used packages.
Applications
SIST EN 4840-001:2018 applies primarily to the aerospace industry where heat shrinkable moulded shapes are used for:
- Electrical Insulation - Protecting aircraft wiring and cable assemblies from mechanical damage and environmental exposure.
- Environmental Sealing - Providing reliable sealing against moisture, dust, and chemicals for aerospace components.
- Mechanical Protection - Offering abrasion resistance and strain relief in complex aerospace assemblies.
- Identification and Colour Coding - Assisting maintenance and safety through standardized colour options that align with IEC 60304 specifications.
These heat shrinkable shapes ensure safety, reliability, and longevity of aerospace systems operating under harsh environmental and mechanical stresses.
