SIST EN ISO 22631:2019 PDF

Overview

EN ISO 22631:2019 - titled Adhesives - Test method for adhesives for floor and wall coverings - Peel test - is a CEN-endorsed adoption of ISO 22631:2019. It specifies a laboratory test method to measure the peel adhesion of resilient or textile floor coverings and wall coverings (note: wall covering excludes wallpaper) bonded to a substrate. The method quantifies resistance to peel forces before and after specified conditioning to help assess adhesive performance and durability.

Key Topics and Requirements

• Scope and purpose: Measures peel resistance of coverings bonded to substrates under defined conditions; intended for resilient and textile coverings.
• Substrates: Uses either fibre cement (autoclaved, ~8 mm thick panels) or plywood (~5 mm thick panels). Panel width is (50 ± 0.5) mm; test covering pieces are typically 250 mm × 50 mm.
• Apparatus:
  • Notched trowel (notch dimensions set by adhesive manufacturer).
  • Roller (example: 60 ± 5 mm width, mass ~3.50 ± 0.05 kg).
  • Heating/conditioning chamber (20–200 °C adjustable per ISO 9142).
  • Tensile testing machine meeting ISO 7500-1 (class 1).
  • Peeling device with specified rolls.
• Specimen preparation:
  • Cleaning, adhesive sampling (ISO 15605), and conditioning of materials at (23 ± 2) °C and (50 ± 5) % RH (ISO 554).
  • Fibre-cement panels are preheated (e.g., 6 h at ~80 °C) then reconditioned before use.
  • Adhesive applied with a notched trowel and rolled to ensure uniform contact.
• Test procedure and evaluation:
  • Peel resistance is measured using a tensile testing machine and peeling device.
  • Results reported for specified conditioning sequences and expressed according to the standard’s evaluation rules.
• Safety and environmental notes: Normal laboratory practice and responsible waste disposal recommended.

Applications and Who Uses It

• Adhesive manufacturers - product development, quality control, and comparative performance data.
• Flooring and wall-covering manufacturers - validating adhesive/covering compatibility.
• Independent test laboratories and certification bodies - standardized testing for compliance and claims.
• Specifiers, architects, and installers - selecting adhesives suited to substrates (fibre cement or plywood) and service conditions.
• R&D teams - ageing studies and formulation optimization.

Related Standards

• Supersedes EN 1372:2015; identical to ISO 22631:2019.
• Normative references include ISO 472, ISO 554, ISO 7500-1, ISO 9142, ISO 10365, ISO 15605, and EN 1067.
