Overview

EN ISO 22635:2019 specifies a laboratory test method for adhesives used with plastic or rubber floor coverings and wall coverings (excluding wallpaper). The standard measures dimensional changes of a bonded covering/substrate assembly after defined accelerated ageing cycles to assess long‑term dimensional stability and the suitability of adhesive–covering combinations.

Key topics and technical requirements

• Scope & principle: Monitors dimensional change of a covering bonded to a substrate during predefined conditioning sequences to give a quantitative measure of suitability.
• Specimens: Test covering pieces typically (250 × 250) mm or (300 × 300) mm bonded to a fibre cement panel (approx. 8 mm thickness).
• Apparatus:
  • Notched trowel (notch shape per adhesive manufacturer specification).
  • Roller: ~60 mm width, 90 mm diameter, total mass ~3.50 kg for consolidation.
  • Heating chamber: ventilated, adjustable between about 20 °C and 200 °C (per ISO 9142 guidance).
  • Measuring device: elongation meter or comparable instrument capable of 0.01 mm resolution over 200–250 mm.
• Preparation & conditioning:
  • Conditioning of fibre cement substrate (example: 6 h at 80 ± 2 °C).
  • Fixing datum points/gauge studs to measure changes parallel and perpendicular to grain; edge‑to‑edge measurement options.
  • Application of adhesive (including primers if required) and bonding under defined procedures.
• Procedure: Preconditioning → accelerated ageing conditioning cycles → subsequent cycles; measure and report dimensional change.
• Results & reporting: Specifies evaluation, expression of results and test report content. Safety and environmental disposal notes are included.

Applications and practical value

• Product development & R&D: Compare adhesive formulations and select adhesives that minimize dimensional drift for vinyl, LVT, rubber or other resilient coverings.
• Quality control: Routine testing to confirm production batches meet dimensional stability expectations after simulated ageing.
• Specification & procurement: Provide objective data for architects, specifiers and contractors when choosing adhesive/covering systems for floors and walls.
• Conformity assessment & certification: Laboratory testing used by test houses and certification bodies to demonstrate compliance with client or regulatory requirements.
• Installers & manufacturers: Helps prevent installation failures due to shrinkage, expansion or bond failure by understanding adhesive performance over time.
