General Information
Overview
EN 2839:2013 is a CEN (Aerospace series) standard that specifies the required properties for chloroprene rubber (CR) - heat resistant, hardness 80 IRHD - intended for aerospace applications. The standard defines material application guidance, prescribed test methods and acceptance criteria (referencing EN 3207 and ISO methods), and designation rules for suppliers and manufacturers. It focuses on durability against atmospheric ageing, ozone, and moderate exposure to petroleum-based fluids.
Key topics and technical requirements
- Material type: Chloroprene rubber (CR), heat resistant, symbol per ISO 1629.
- Hardness: 80 IRHD (specified target).
- Service temperature range:
- Continuous service: −40 °C to 120 °C
- Intermittent service: −40 °C to 150 °C
- Mechanical minima: tensile strength ≥ 15 MPa; elongation at break ≥ 150% (from Table 1).
- Low temperature behavior: TR10 ≤ −25 °C.
- Compression set: ≤ 40% after 24 h at 125 °C (batch acceptance).
- Ozone resistance: no cracking under specified ozone exposure (50 ± 5 pphm, 20% elongation, 70 h at 30 °C).
- Corrosion/adhesion on metals: no corrosion and no adhesion after 168 h at 100 °C.
- Density control: batch density shall not differ from qualification value by more than 0.02 Mg/m3.
- Testing and acceptance: Test methods and acceptance limits are given in Table 1 and Table 2; qualification requires the full test set, while batch acceptance requires tests marked for batch control (footnote “a”). Referenced standards: EN 3207, ISO 1629 and ISO 1817.
Applications and who uses EN 2839
- Primary applications: seals, gaskets, vibration mounts, hoses and other elastomer parts in aircraft systems where ozone resistance, atmospheric ageing resistance and moderate fuel/oil resistance are required.
- Typical users: aerospace OEMs, parts suppliers, materials engineers, quality and procurement teams, test laboratories and certification bodies.
- Benefits: ensures material consistency, traceability and interchangeability of CR parts across the aerospace supply chain; supports compliance with aerospace material specifications and procurement contracts.
