Overview

EN ISO 10545-10:2021 is an international standard specifying a reliable and precise method for the determination of moisture expansion in ceramic tiles. Developed collaboratively by ISO Technical Committee ISO/TC 189 and CEN Technical Committee CEN/TC 67, this standard provides the framework to test how ceramic tiles expand when exposed to moisture, particularly under accelerated conditions involving boiling water immersion. The standard, updated and corrected in 2021, replaces the earlier 1997 version to reflect current testing needs and ensure uniform quality control in the ceramic tile industry.

Understanding moisture expansion is crucial because it affects tile durability, installation quality, and long-term performance. Excessive moisture expansion can lead to tile deformation, cracking, or adhesion failure, particularly in variable climatic conditions or with improper substrate preparation.

Key Topics

• Purpose and Scope: Defines a standardized approach to quantitatively measure moisture-induced expansion in ceramic tiles, enabling consistent quality assessment.
• Test Principle: Involves refiring the tile specimen followed by 24-hour immersion in boiling deionized or distilled water to accelerate moisture expansion. Changes in length are precisely measured using a calibrated measuring frame.
• Specimen Preparation:
  • For tiles ≤3600 cm², whole tiles or central cut specimens (minimum 100 mm length, 35 mm width) are tested.
  • For tiles >3600 cm², specimens are cut from the tile center ensuring they fit the measuring apparatus.
• Testing Apparatus: Requires a kiln (up to 600°C), a measuring frame with micrometer or dial gauge (accuracy ≥0.01%), reference bars of Invar steel, and boiling water setup.
• Measurement Procedure: Initial and post-immersion lengths of specimens are recorded. Measurements take into account thermal stabilization and include repeat tests for reliability.
• Result Expression: Moisture expansion is calculated both in millimeters per meter (mm/m) and as a percentage (%), supporting versatile reporting.
• Reporting Requirements: Test reports must reference the standard, describe tile types and specimen sizes, record individual specimen expansions highlighting maxima, and provide average expansion values.

Applications

Compliance with EN ISO 10545-10:2021 is essential for:

• Ceramic tile manufacturers ensuring products meet moisture expansion performance criteria before market release.
• Quality control laboratories validating tile durability and dimensional stability under moisture exposure.
• Architects and engineers specifying tile types appropriate for environments subject to high humidity or moisture.
• Construction and installation, minimizing risks of tile failure due to moisture-induced deformation by selecting compliant products.
• Research and development aiming to improve ceramic tile formulations and surface treatments to optimize moisture resistance.
• Regulatory compliance within European and international markets, as the standard is harmonized across multiple countries through CEN.

The accurate assessment of moisture expansion informs better design, installation, and maintenance practices, thereby prolonging tile service life and preventing installation failures related to substrate movement and climatic changes.

Related Standards

Key related standards that complement EN ISO 10545-10:2021 and cover various quality and performance aspects of ceramic tiles include:

• EN ISO 10545-1 to EN ISO 10545-9: Cover dimensions, water absorption, mechanical strength, resistance to chemicals, thermal shock, frost resistance, and more.
• EN ISO 10545-2: Determination of dimensions and surface quality.
• EN ISO 10545-4: Determination of modulus of rupture and breaking strength.
• EN ISO 10545-6: Resistance to deep abrasion.
• EN ISO 10545-12: Thermal shock resistance testing.
• ISO 10545 series: Provides a harmonized suite of tests to comprehensively evaluate ceramic tile performance.

Utilizing EN ISO 10545-10:2021 in conjunction with these standards ensures a holistic approach to monitoring and guaranteeing the quality of ceramic tiles in production, supply, and application.

---

By adhering to EN ISO 10545-10:2021, industry stakeholders benefit from standardized, accurate determination of moisture expansion-a key factor influencing the structural integrity and longevity of ceramic tile installations. This fosters trust, quality assurance, and compliance within the international ceramic tile market.
