General Information
Overview
EN 2567:2019 is a European aerospace standard that defines the required properties and testing regime for fluorocarbon rubber (FKM) with a nominal hardness of 80 IRHD. Published by CEN and prepared by ASD-STAN, this standard targets FKM materials used in aerospace environments where resistance to air, hydrocarbon and synthetic oils, and fuels at elevated temperatures is required. It specifies mechanical, thermal and chemical performance limits and identifies which tests are required for qualification and batch acceptance.
Key Topics
- Material and scope: Fluorocarbon rubber (FKM) - aerospace series - hardness 80 IRHD.
- Temperature service range:
- Continuous service: −20 °C to 225 °C
- Intermittent service: −20 °C to 250 °C
- Mechanical requirements (selected):
- Hardness: 80 IRHD (batch acceptance)
- Tensile strength: ≥ 11 MPa (batch acceptance)
- Elongation at break: ≥ 150% (batch acceptance)
- Density: controlled per standard (batch acceptance)
- Low temperature and aging:
- TR10: ≤ −12 °C
- Compression set: after 24 h at 200 °C ≤ 35% (batch acceptance); after 70 h at 200 °C ≤ 65%
- Chemical resistance tests: Exposure to representative liquids (see ISO 1817) with post‑exposure limits on mass, volume, tensile strength, elongation and hardness.
- Qualification vs batch acceptance:
- All tests are required for material qualification.
- A reduced set (marked “∗” in the standard) is required for routine batch acceptance.
Applications
EN 2567:2019 is intended for specifying FKM elastomer materials used in aerospace seals, O‑rings, gaskets, hoses and other components that must withstand:
- High temperatures and intermittent thermal spikes
- Hydrocarbon and synthetic oils, aviation fuels and lubricants
- Oxidative and ozone exposure typical in aircraft environments
Who uses this standard:
- Aerospace materials engineers and designers selecting elastomers
- Quality and procurement teams specifying supplier acceptance tests
- Manufacturers of elastomer seals and components for airframe and engine systems
- Certification and testing laboratories performing material qualification
Related Standards
- EN 3207 - Aerospace series - Rubber compounds - Technical specification (technical specification reference)
- ISO 1817 - Rubber, vulcanized - Determination of the effect of liquids (chemical resistance testing)
- ISO 1629 - Rubber and latices - Nomenclature
EN 2567:2019 should be referenced when you need a standardized specification for FKM 80 IRHD in aerospace applications, ensuring consistent testing, acceptance criteria and material performance for critical sealing components.
