Overview

EN 3827:2014 is a European standard developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN) and approved by CEN. This standard specifies the key properties and requirements for fluorosilicone rubber (FVMQ) with a hardness of 80 on the IRHD scale, specifically tailored for aerospace applications. Fluorosilicone rubber is valued in the aerospace sector for its outstanding resistance to extreme temperatures and a wide range of chemical fluids typically encountered in aviation environments.

Key Topics

• Material Specification: Defines the physical and mechanical properties of FVMQ rubber at a hardness of 80 IRHD, including density, tensile strength, elongation at break, tear strength, and compression set.
• Temperature Range: Suitable for continuous aerospace service between −55 °C and 180 °C, and intermittent service up to 200 °C.
• Chemical Resistance: Designed to withstand exposure to petroleum-based fluids, aviation fuels, hydraulic fluids, lubricants, greases, silicone oil, and certain ester-based fluids (excluding phosphate esters).
• Testing Requirements:
  • Qualification involves comprehensive testing of all specified properties.
  • Batch acceptance requires testing of critical parameters marked within the standard.
• Performance After Exposure: Details limits on variations in volume, hardness, tensile strength, and elongation after exposure to specific test media following ISO 1817 procedures.

Applications

EN 3827:2014 is primarily aimed at ensuring reliable material performance in aerospace components where fluorosilicone rubber (FVMQ) is used. Typical uses include:

• Sealing elements exposed to aviation fuels, hydraulic and lubricating fluids.
• Components requiring exceptional thermal stability across a broad temperature spectrum.
• Applications demanding durability against oil, grease, and hydraulic fluids in aerospace environments.

This standard supports quality assurance and material selection for aerospace engineers, designers, and manufacturers to meet rigorous reliability and safety standards in aircraft and spacecraft systems.

Related Standards

• ISO 1629 - Rubber and latices nomenclature: Defines the classification and symbols for rubber material, including fluorosilicone rubber (FVMQ).
• ISO 1817 - Rubber, vulcanized - Determination of the effect of liquids: Specifies test methods for assessing chemical resistance of rubber materials in fluids.
• EN 3207 - Aerospace series - Rubber compounds - Technical specification: Provides technical specifications complementing EN 3827 regarding rubber compounds used in aerospace.

Compliance with these related standards ensures that fluorosilicone rubber materials meet the industry-wide benchmarks for performance, testing, and safety within aerospace applications.
