Overview

EN 2667-6:2001 is a CEN/AECMA European Standard that defines test methods for determining the water absorption of foaming structural adhesives used in aerospace applications. It covers procedures for exposing cured, expanded adhesive test pieces to high humidity or immersion in distilled water, and for calculating water uptake and any water‑soluble matter lost. The standard supports consistent materials characterization and quality control of non‑metallic foaming structural adhesives.

Key topics and technical requirements

• Scope: water absorption testing of foaming structural adhesives under humidity or immersion conditions.
• Test specimens: cut from cured and expanded samples; edges free from cracks; three test pieces per method; thickness measured as average of four corner measurements to ±0.2 mm.
• Apparatus and accuracy: balance accurate to 1 mg; ovens capable of 110 ±3 °C and 50 ±3 °C; humidity cabinet at 50 ±3 °C and 95–100% relative humidity; distilled water and absolute alcohol.
• Conditioning: pre‑conditioning in oven at 110 ±3 °C for 24 h, cooled in a desiccator and weighed (mass M2).
• Test methods:
  • 14 days immersion: complete immersion in distilled water at 25 ±3 °C; post‑test rinse in absolute alcohol, 1 min drying at 50 ±3 °C, cool and weigh (mass M3).
  • 14 days humidity: exposure in humidity cabinet at 50 ±3 °C, 95–100% RH for 14 days; cool and weigh (mass M3).
• Reconditioning: return to conditioning (110 ±3 °C) and weigh (mass M4) to detect soluble matter loss.
• Calculations and results: compute mass loss due to conditioning, mass increase from water absorption (percentage and mg/cm3 using specimen volume), soluble matter lost, and report combined water absorption values.
• Test report must include full adhesive identification (type, manufacturer, batch), curing and expansion details (EN 2667‑3 expansion ratio), dimensions, conditions, individual and mean results, observations and deviations.

Applications and users

• Primary users: aerospace manufacturers, adhesives suppliers, materials engineers, test laboratories, quality assurance and procurement teams involved with structural bonding in aircraft and spacecraft.
• Practical uses:
  • Evaluate durability of foaming adhesives under humid environments or water immersion.
  • Support material selection, qualification, batch verification and supplier acceptance testing.
  • Aid failure analysis and environmental performance comparisons for adhesive systems.
