Overview - EN ISO 22632:2019 (Shear test for adhesives)
EN ISO 22632:2019 specifies a laboratory shear test method to measure the adhesion of resilient or textile floor coverings and wall coverings (note: excludes wallpaper) bonded to defined substrates. The procedure quantifies shear strength of adhesive bonds under controlled conditions and after defined conditioning/ageing, enabling manufacturers and test laboratories to evaluate adhesive performance and durability.
Key topics and technical requirements
- Scope and purpose: Measures adhesion of coverings to substrates under shear forces; used for product development, quality control and comparative testing.
- Specimens and dimensions: Test coverings cut to 60 mm × 50 mm (long side in machine direction); substrates are either fibre cement (≈8 mm thick) or plywood (≈5 mm thick).
- Apparatus: Notched trowel (manufacturer-specified notch shape), roller (≈60 mm width, 3.50 kg mass), ventilated heating chamber (20–200 °C), and a tensile testing machine conforming to ISO 7500-1.
- Preparation and application: Adhesive sampling per ISO 15605 and EN 1067; surfaces cleaned; adhesive applied with a notched trowel at ~60°; roller used to ensure uniform contact.
- Conditioning: Materials conditioned in a standard atmosphere of (23 ± 2) °C and (50 ± 5) % RH (ISO 554). Fibre cement panels receive pre‑heating treatment as specified; elevated laboratory ageing options follow ISO 9142.
- Test procedure: Shear strength is measured before and after specified conditioning/ageing. Failure patterns are classified per ISO 10365.
- Results and reporting: Results expressed as shear strength with description of failure mode, test conditions, substrate type and sample preparation details.
Practical applications and users
Who uses EN ISO 22632:2019:
- Adhesive and flooring manufacturers - product development and validation of bond performance.
- Independent test laboratories - standardized comparative testing and certification.
- Specifiers, procurement and quality teams - verification of adhesive suitability for intended substrates and service conditions.
- Contractors and building inspectors - reference for performance requirements in technical specifications.
Typical uses:
- Quality control batch testing, R&D screening of adhesive formulations, compliance evidence for technical datasheets, and comparative performance benchmarking across adhesives and substrates.
