Full title and description

ISO 10545-10:2021 — Ceramic tiles — Part 10: Determination of moisture expansion. This international standard specifies a laboratory test method to determine the dimensional change (moisture-induced expansion) of ceramic tiles when exposed to moisture-conditioning procedures.

Abstract

Specifies a procedure for measuring moisture expansion of ceramic tiles (the proportional change in length after a defined conditioning sequence); it replaces the earlier 1995 edition and provides the current, harmonized test method for industry and testing laboratories.

Scope

ISO 10545-10:2021 defines a laboratory procedure to determine the moisture expansion of ceramic tiles. The standard describes specimen preparation, conditioning and the measurement sequence used to quantify the proportional change in length (expressed as moisture expansion) after exposure to the specified moisture treatment. The method is intended for use when characterizing tile dimensional behavior in humid or wet conditions and for quality control and conformity testing.

Key topics and requirements

• Definition of moisture expansion and the metric used to report proportional change in length (moisture-induced dilatation).
• Specimen selection and preparation requirements (size, reheating or drying as required before conditioning).
• Conditioning procedure (controlled exposure — historically involves a reheating step and immersion/boiling sequence or equivalent defined moisture treatment) and timing to develop measurable expansion.
• Measurement methods for determining length change and calculation of percentage expansion.
• Reporting requirements and notes on repeatability/precision for test laboratories.

Typical use and users

Used by ceramic tile manufacturers, independent testing laboratories, product conformity assessors, architects and specifiers for product data sheets, and by regulatory or accreditation bodies to verify dimensional stability in humid conditions. The standard is commonly purchased and applied by industry testing organizations as part of tile physical property test programs.
