Overview

EN 13408:2002 is a CEN standard that specifies a laboratory test method for determining bond strength between a cured hydraulic‑setting floor smoothing and/or levelling compound and a standard substrate (concrete test slab). The method measures the tensile (pull‑off) strength of a defined bonded area using metal plates adhered to the compound and removed with a tensile testing machine. This standard is used to assess adhesion performance and to compare products under controlled conditions.

Key topics and requirements

• Test principle: Measure tensile force required to detach a metal plate bonded to the compound; report breaking load and mode of failure.
• Standard conditions: 23 ± 2 °C and 50 ± 5 % RH (ISO 554); air circulation < 0.2 m/s. Precondition materials for ≥ 24 h.
• Specimens: Eight test areas per compound, using silicone moulding sheets with 50 ± 1 mm square cavities (bonded area = 2 500 mm²).
• Timing: Test performed 14 days after mixing the smoothing/levelling compound. Metal plates are bonded to test areas within 24 hours prior to testing and adhesive must be cured.
• Apparatus & materials:
  • Tensile testing machine with suitable connector
  • Concrete slab per EN 1323
  • Moulding sheets (~400 × 400 mm, ~5.0 ± 0.5 mm thickness or manufacturer’s max application thickness)
  • Fast‑setting reactive resin adhesive (epoxy, polyurethane, methyl methacrylate)
  • Rigid metal plates (~50 × 50 mm; steel ≥ 5 mm, aluminium ≥ 10 mm)
  • Compound mixed per EN 1937; primer if specified
• Test execution: Apply tensile load at 250 ± 50 N/s until failure. Record load (N) and failure mode per EN ISO 10365 (cohesive in compound, cohesive in substrate, adhesive failure).
• Calculation & evaluation: Bond strength (MPa) = breaking load (N) ÷ bonded area (mm²). Compute arithmetic mean of eight results; discard values that differ by > 20 % from the mean (repeat until stable). If fewer than four results remain, repeat the test.

Applications and users

• Practical uses:
  • Product development and quality control for floor smoothing/levelling compounds
  • Comparative performance testing for material selection
  • Verification of manufacturer adhesion claims and installation compatibility with concrete substrates
  • Compliance testing for specification and procurement
• Typical users:
  • Manufacturers of hydraulic‑setting smoothing and levelling compounds
  • Independent testing laboratories and certification bodies
  • Architects, specifiers, and contractors assessing material performance
  • R&D teams optimizing primer and adhesive systems

Related standards

• EN 1323 - Concrete slab for test (adhesives for tiles)
• EN 1937 - Standard mixing procedure for hydraulic‑setting floor smoothing/levelling compounds
• EN ISO 10365 - Designation of main failure patterns
• ISO 554 - Standard atmospheres for conditioning/testing

EN 13408:2002 is a practical, repeatable method for assessing substrate bond strength and ensuring consistent adhesive performance of hydraulic setting floor smoothing and levelling compounds.
