Overview
EN ISO 22633:2019 - "Adhesives - Test methods for adhesives for floor coverings and wall coverings - Determination of dimensional changes of a linoleum floor covering in contact with an adhesive" is a CEN-endorsed ISO test method that describes a laboratory procedure to measure dimensional changes of linoleum when bonded to an impervious substrate (glass). The method is intended for use alongside other test methods and is not to be used alone to decide suitability of an adhesive/linoleum combination.
Key topics and requirements
- Scope: Quantifies dimensional movement of linoleum during the early drying/bonding stages when in contact with an adhesive on glass (maximizes effect compared with porous substrates).
- Test principle: Monitor dimensional change as adhesive dries; provides an indication of movement caused by adhesive interaction and moisture transfer.
- Apparatus & materials:
- Notched trowel (notch geometry per adhesive manufacturer).
- Roller: width (60 ± 5) mm, diameter (90 ± 5) mm, mass (3.50 ± 0.05) kg.
- Glass plates (≥6 mm thick), typically 300 × 300 mm or 350 × 350 mm.
- Measuring device capable of 0.01 mm accuracy over 200 mm or 250 mm (e.g., elongation meter).
- Linoleum specimens: 250 × 250 mm or 300 × 300 mm.
- Gauge studs or adhesive for attaching reference points; square metal plate providing ≈5 kg load.
- Specimen preparation:
- Pre‑treatment to flatten linoleum: stack pairs in an oven at 50 °C for 24 h under 5 kg, then cool at standard atmosphere (23 °C / 50 % RH) for 24 h.
- Conditioning: glass plates, linoleum and adhesive conditioned at 23 °C / 50 % RH for 10 days (ISO 554).
- Measurement & procedure:
- Fix datum/gauge points near specimen edges.
- Apply adhesive (per manufacturer), bond to glass, roll to ensure contact.
- Measure reference dimensions and record dimensional changes during adhesive drying.
- Reporting: Test report includes method details, environmental conditions, materials, measured dimensional changes and any deviations.
Practical applications and users
- Who uses it:
- Adhesive manufacturers (R&D and QC) - compare formulations for dimensional impact.
- Linoleum producers - assess interactions with adhesives.
- Independent testing laboratories - provide standardized test data for compliance and product datasheets.
- Specifiers / flooring contractors - inform installation guidance and product selection when dimensional stability is critical.
- Practical uses:
- Product development, quality control, comparative testing, failure analysis and technical documentation for safety and performance claims.
