Full title and description

ISO 10545-8:2014 — Ceramic tiles — Part 8: Determination of linear thermal expansion. This International Standard specifies a test method to determine the coefficient of linear thermal expansion of ceramic tiles (coefficient of thermal expansion, CTE) under controlled heating conditions.

Abstract

ISO 10545-8:2014 defines the procedure for measuring the linear thermal expansion of ceramic tiles (typically from ambient temperature up to 100 °C), including specimen preparation, test conditions, calibration of the measuring apparatus and how results are reported (coefficient of linear expansion). The method is intended to provide reproducible values for use in production control, conformity assessment and comparative testing.

Scope

This part of ISO 10545 specifies a method to determine the coefficient of linear thermal expansion of ceramic tiles by measuring dimensional change under a controlled increase in temperature (commonly from ambient temperature up to 100 °C). It applies to ceramic tiles where linear thermal expansion data are required for design, quality control and conformity assessment. The method includes requirements for specimen orientation, calibration and reporting of results.

Key topics and requirements

• Definition of the coefficient of linear thermal expansion (CTE) for ceramic tiles and required units of expression (typically 10‑6/°C).
• Specimen preparation and selection: two specimens tested at right angles to one another to account for anisotropy.
• Temperature range and heating rate: measurement typically from ambient to 100 °C under a controlled heating regime.
• Calibration and use of a standard specimen of the same dimensions for apparatus calibration before testing.
• Calculation and reporting of linear expansion coefficients and any observed anisotropy or test deviations.

Typical use and users

Used by ceramic tile manufacturers for product development and quality control, independent testing laboratories performing conformity and performance testing, certification bodies, façade and floor product specifiers, architects and engineers who require reliable CTE data for design and compatibility assessments (for example to avoid stresses with substrates or adjacent materials). Test houses and national standards bodies also use this standard for harmonized testing.

Related standards

ISO 10545 is a multipart series covering many test methods for ceramic tiles. Closely related parts include ISO 10545-1 (sampling), -2 (dimensions and surface quality), -3 (water absorption and density), -9 (resistance to thermal shock), -10 (moisture expansion) and other parts addressing mechanical, chemical and durability properties — all commonly referenced together when assessing tile performance. National/adopted versions (EN, NF, UNE, TCVN, etc.) may incorporate ISO 10545-8 with regional forewords.
