DIN EN 2432 1995-11 PDF

Full title and description

STB DIN EN 2432:1995-11 — Aerospace series: Ethylene‑propylene rubber (EPM/EPDM) — Hardness 90 IRHD. German-language DIN adoption of the European standard EN 2432, specifying the required properties and associated test and verification criteria for EPM/EPDM elastomers with a nominal hardness of 90 IRHD for aerospace applications.

Abstract

This standard defines material requirements, physical properties and testing criteria for ethylene‑propylene elastomers (EPM/EPDM) formulated to a hardness of 90 IRHD for use in aerospace components. It establishes the characteristic property values, dimensional and manufacturing notes relevant to procurement, verification and quality control of rubber parts intended for aircraft and space applications.

General information

Scope

The standard applies to ethylene‑propylene rubbers (EPM and EPDM) manufactured for aerospace use with a target hardness of 90 IRHD. It specifies the characteristic physical properties (including hardness limits and tolerances), testing methods or references to test methods, marking and identification requirements relevant to aerospace procurement and quality control. The scope covers material property specifications rather than component design requirements.

Key topics and requirements

• Definition and designation of EPM/EPDM compound intended for aerospace use at 90 IRHD nominal hardness.
• Specified hardness value (90 IRHD) with allowable tolerances and method of measurement (IRHD method reference).
• Required physical property limits and characteristic values (typical clauses include tensile strength, elongation at break, compression set, density and other acceptance criteria — actual numeric limits are given in the standard text).
• Referenced test methods and preparation of test specimens for verification.
• Marking, labelling and documentation expectations for supplied material or sheets intended for aerospace use.
• Notes on intended application domain (aerospace components) and limitations (material specification, not detailed component design).

Typical use and users

Primary users are aerospace manufacturers, rubber compound formulators and suppliers, quality assurance and testing laboratories, procurement specialists specifying elastomer materials for aircraft/space components, and certification bodies reviewing material compliance for aerospace qualification. The standard is used when ordering material (sheets, seals, molded parts) or establishing vendor acceptance criteria.

Related standards

This document is part of a family of aerospace-series elastomer material specifications. Closely related standards in the series specify other hardness grades and different elastomer types (for example EN 2430, EN 2431, EN 2428/2429 for other hardness values or related elastomers). It is common to consult relevant EN/DIN material and test standards (and any ISO test method references) when applying EN 2432.

FAQ

Q: What is this standard?

A: DIN EN 2432:1995-11 is the German-language DIN publication of the European standard EN 2432 (1995) that specifies material requirements for ethylene‑propylene rubbers (EPM/EPDM) with a nominal hardness of 90 IRHD for aerospace applications.

Q: What does it cover?

A: It covers material property specifications, hardness tolerances, referenced test methods and supplier/acceptance information for EPM/EPDM formulated to 90 IRHD intended for use in aircraft and space industry components. It does not prescribe component designs.

Q: Who typically uses it?

A: Aerospace OEMs and their suppliers, rubber compounders producing EPM/EPDM grades for aerospace, QA/test laboratories verifying compliance, and procurement/specification engineers selecting elastomer materials for aerospace parts.

Q: Is it current or superseded?

A: The document shown here is the DIN publication of EN 2432:1995 (DIN EN 2432:1995-11). National statuses can vary over time — some catalogues list the 1995 edition as published/active while historical records may show drafts or earlier PREN stages; therefore users should confirm the current legal or normative status with their national standards body (e.g., DIN, BSI, SN, NEN) before use.

Q: Is it part of a series?

A: Yes — EN 2432 belongs to a family of aerospace-series elastomer material specifications that cover various elastomer types and hardness grades (other EN 24xx documents specify different hardnesses and elastomer classes). When specifying material, consult the relevant series members and referenced test standards.

Q: What are the key keywords?

A: EPDM, EPM, ethylene‑propylene rubber, IRHD, hardness 90, aerospace, DIN EN 2432, material specification, rubber testing.
