Overview

EN 2243-1:2005 - "Aerospace series - Non‑metallic materials - Structural adhesives - Test method - Part 1: Single lap shear" is a CEN (AECMA) test standard for measuring the shear strength of structural adhesives in metal‑to‑metal single lap shear specimens. It specifies specimen geometry, surface preparation, bonding and storage, test conditions (ambient and elevated temperatures), test machine requirements and the data to report. This standard is used to generate repeatable, comparable shear strength data for aerospace adhesive qualification and material selection.

Key topics and requirements

• Specimen design and materials
  • Defined panel and test piece dimensions; rolling direction parallel to specimen axis.
  • Acceptable metal substrates include aluminium alloys (per EN 2087/2088/2090/2092), corrosion‑resisting steel (EN 2540) and titanium alloys (EN 2517/EN 3456/EN 3464) depending on test temperature and adhesive strength.
• Surface preparation
  • Pre‑bond treatments reference EN 2334 (chromic‑sulphuric acid pickle) and EN 2497 (dry abrasive blasting for titanium).
• Bonding and storage
  • Adhesive application, primers and cure follow the adhesive manufacturer’s instructions or material standard.
  • Post‑cure storage: (23 ± 2) °C and (50 ± 5) % RH for 16 h unless otherwise specified.
• Test conditioning and temperature control
  • Tests may be at ambient or elevated temperatures; heating rate 6–10 °C/min. For non‑ambient tests, hold the specimen at temperature for 10 min before loading.
  • Thermocouple placement is specified (junction on metal within a 6 × 7 mm area inside the bonded zone) for accurate temperature control.
• Mechanical test parameters
  • Specimens gripped 50 ± 5 mm from each edge of the lap.
  • Loading rate: 2 800 N/min to 5 000 N/min.
  • Tensile machine accuracy: load recorded to ±1 %; failing load should be within 10–90 % of machine range.
• Result calculation and reporting
  • Shear strength R = F / (L × W) where F = failing load (N), L = loaded length (mm), W = overlap width (mm).
  • Test report must include adhesive identification, substrate details, surface prep, cure/bonding parameters, test conditions, individual results, failure mode distribution and any deviations.

Applications and users

• Primary users: adhesive manufacturers, aerospace OEMs, material qualification labs, test houses and certification bodies.
• Practical uses:
  • Qualifying structural adhesive systems for aircraft assemblies.
  • Comparing adhesive performance across temperatures and substrates.
  • Supporting material selection, design validation and procurement specifications in aerospace programs.
