ISO 10545-24:2026

Overview

ISO 10545-24:2026 defines a standardized method for determining the tensile adhesion strength of fibre-combined multilayer ceramic tiles, specifically evaluating the bond between the back of these tiles and the cementitious adhesives used for installation. This standard ensures objective, reproducible results vital for quality assurance and compliance in ceramic tile installation projects.

Fibre-combined multilayer ceramic tiles, also known as reinforced or back-layered ceramic tiles, incorporate a mesh of glass fibre on their reverse side to enhance structural integrity. Measuring their adhesive performance is essential for safe, durable installations in residential, commercial, and industrial environments.

Key Topics

• Tensile Adhesion Testing: ISO 10545-24 details procedures for sampling, conditioning, and testing fibre-combined multilayer ceramic tiles using a cementitious adhesive classified as at least C2S1 type in accordance with ISO 13007-1.
• Testing Conditions: The standard specifies normal laboratory conditions of 23 ± 2 °C temperature and 50 ± 5% relative humidity to ensure consistent results.
• Failure Modes: Multiple potential failure patterns are recognized, including adhesion failure at the adhesive/substrate or adhesive/tile interface, and cohesive failures within the adhesive layer, substrate, or tile.
• Environmental Durability: Adhesion is assessed after various exposures such as water immersion, heat ageing, and freeze-thaw cycling, reflecting real-world service conditions.
• Reporting Requirements: Mandatory parameters for reporting include adhesive type and classification, testing conditions, measured tensile adhesion strengths (individual and mean values), and observed failure patterns.

Applications

Ensuring reliable adhesion strength for fibre-combined multilayer ceramic tiles is crucial in the following applications:

• Quality Assessment: Manufacturers use this ISO standard to verify product reliability and compliance with regulatory or project requirements.
• Product Development: Research and development teams utilize these testing methods to improve tile design and optimize adhesive formulations.
• Construction and Installation: Specifiers, contractors, and installers consult ISO 10545-24 testing data to select appropriate tile and adhesive combinations for high-performance flooring and wall cladding systems.
• Third-Party Testing: Accredited laboratories follow this standardized procedure to provide independent certification of adhesive performance for tile manufacturers and suppliers.

Adhering to ISO 10545-24:2026 improves confidence in the long-term performance of tiled surfaces, especially where fibre-combined multilayer ceramic tiles are required for enhanced strength or larger formats.

Related Standards

ISO 10545-24:2026 is part of the broader ISO 10545 series on ceramic tile testing. Notable related standards include:

• ISO 10545-1 to ISO 10545-23: Cover various aspects of ceramic tile test methods, including dimensionality, surface quality, and durability.
• ISO 13007-1: Defines terms, specifications, and classification codes for ceramic tile adhesives and grouts, referenced here for adhesive requirements.
• ISO 13007-2: Specifies test methods for adhesives used with ceramic tiles, essential for preparing and evaluating test substrates.

Alignment with these standards promotes harmonized testing methodologies across the tile manufacturing supply chain and supports global trade in ceramic tiles and related installation materials.
