Approved by CEN, the standard targets materials intended for aerospace applications where combined resistance to petroleum-based fuels and low temperatures is essential.
Key factual points from the standard:
- Material: Acrylonitrile-butadiene rubber (NBR)
- Hardness: 70 IRHD
- Typical use: resistance to petroleum-based fuels and lubricants together with low temperature resistance
- Service temperature range: continuous −45 °C to 110 °C, intermittent −45 °C to 130 °C
- Reference normative documents: EN 3207, ISO 1629, ISO 1817
Key Topics
- Material identification and application: EN 3698 follows ISO 1629 nomenclature and defines the NBR grade for aerospace use.
- Performance and test requirements: Properties are specified in tables (Table 1 and Table 2) referenced to EN 3207. For qualification all tests listed in the standard are required; for batch acceptance a subset of tests (identified by footnote "a") must be performed.
- Resistance to media: The standard references ISO 1817 for determination of the effect of liquids (oil/fuel exposure) and specifies permitted variations in mass, volume and mechanical properties after exposure.
- Low-temperature behaviour: Low-temperature flexibility and crystallization limits are included to ensure performance in cold operating environments.
Applications
EN 3698:2013 is intended for aerospace components where exposure to fuels and lubricants coincides with low ambient or operational temperatures. Practical application examples include elastomer parts used in fuel systems and other aircraft systems that demand:
- Reliable fuel and lubricant resistance
- Stable mechanical properties at low temperatures
- Consistent production batch acceptance and traceability for safety-critical parts
The suitability of the material for a specific component should be verified by complementary tests on finished parts, since the standard properties are obtained from standard test specimens.
