EN 14258:2004 - Structural adhesives - Mechanical behaviour of bonded joints subjected to short and long terms exposure at specified conditions of temperature

Overview

EN 14258:2004 (CEN) provides guidelines to evaluate the mechanical behaviour of structural adhesives and bonded joints when exposed to specified temperature conditions for short and long periods. The standard focuses on the measurement of shear properties of adhesively bonded joints to determine heat resistance for both thermoplastic and thermosetting structural adhesives. It clarifies scope, apparatus, specimen preparation, conditioning and reporting requirements without prescribing application suitability limits.

Keywords: structural adhesives, bonded joints, thermal exposure, heat resistance, shear testing, long-term exposure, short-term exposure.

Key Topics

  • Scope and purpose: Methods to characterise adhesively bonded joints at different temperatures and after continuous thermal exposure; intended for design verification and comparative assessment.
  • Referenced test methods: Selection of specimen and test method depends on adhesive type: EN 14869-2 for design-level thick-adherend shear tests, EN 1465 for many adhesives, and ISO 10123 for anaerobic adhesives. EN ISO 9142 guides selection of ageing conditions.
  • Apparatus and conditioning: Required equipment includes tensile test machines with environmental chambers and controlled thermal ageing chambers. Specimens shall be conditioned for 1 day at (23 ± 2) °C and (50 ± 5) % RH before testing or ageing; after thermal ageing, specimens are conditioned 24 h at (23 ± 2) °C and (50 ± 5) % RH prior to shear testing.
  • Procedure notes: Tests include temperature-dependent shear tests (hold specimen until temperature equilibrium) and long-term thermal exposure tests (exposure time chosen according to application). Test temperatures and exposure profiles should be selected per EN ISO 9142 guidance.
  • Reporting requirements: Test reports must record the test temperature for temperature‑dependent tests and both exposure temperature and duration for long‑term thermal ageing, in addition to information required by the referenced test standards.

Applications

EN 14258:2004 is practical for:

  • Design verification of bonded joints subjected to elevated or reduced temperatures.
  • Comparative assessment when selecting adhesives and bonding processes for temperature-critical applications.
  • Product development and qualification programmes that require documented heat resistance data for adhesive joints.

Practical value derives from consistent test methods, controlled conditioning and clear reporting requirements, enabling repeatable evaluation of shear behaviour under thermal stress.

Note: This standard does not define absolute exposure performance limits or overall suitability of an adhesive for a specific application; selection must consider adhesive, substrate and application interactions. Users should follow normal laboratory safety practices.
