General Information
Overview
EN 2842:2013 is a CEN (European) aerospace standard that specifies the required properties and test criteria for acrylonitrile-butadiene rubber (NBR) that is mineral-oil resistant and manufactured to a hardness of 70 IRHD. It is intended for aerospace applications where resistance to petroleum-based hydraulic fluids and lubricants is required. The standard defines material limits, test methods and conditions for both qualification and batch acceptance.
Key Topics and Technical Requirements
- Material and scope: NBR (symbol per ISO 1629), mineral-oil resistant, hardness 70 IRHD, for aerospace use.
- Operating temperature:
- Continuous service: −40 °C to 120 °C
- Intermittent service: −40 °C to 150 °C
- Mechanical properties (examples from the standard):
- Tensile strength: minimum 10 MPa
- Elongation at break: minimum 200%
- Hardness: 70 IRHD
- Low temperature behavior:
- TR10 (low temperature brittleness): ≤ −25 °C
- Compression set:
- After 24 h at 125 °C: ≤ 35%
- After 70 h at 125 °C: ≤ 40%
- Oil resistance tests: Exposure to oil media (per ISO 1817, e.g., Oil No.1 and Oil No.3) and air at 70 h/125 °C with defined allowable changes in volume, mass, tensile and elongation.
- Corrosion and adhesion on metals: e.g., no corrosion or adhesion after 168 h at 100 °C.
- Qualification vs batch acceptance: Full test battery for qualification; a subset identified in the tables is required for batch acceptance. Density control requires batch values to be within 0.02 Mg/m3 of qualification.
Applications
- Seals, O‑rings, gaskets and vibration-damping parts in aerospace hydraulic and fuel systems exposed to mineral oils.
- Use cases where predictable oil swell, mechanical retention and temperature endurance are critical.
- Material selection and procurement specifications for aircraft OEMs, MROs and suppliers.
Who Uses This Standard
- Aerospace materials engineers and design teams
- Rubber compounders and material manufacturers
- Test laboratories and certification bodies
- Procurement and quality assurance specialists specifying NBR components
