Full title and description

ISO 10545-20:2022 — Ceramic tiles — Part 20: Determination of deflection of ceramic tiles for calculating their radius of curvature. This International Standard specifies a laboratory method to measure the deflection of tile specimens so that the radius of curvature of bent or warped tiles can be calculated for product characterization and quality control.

Abstract

This document specifies a method for measuring the deflection of ceramic tiles for calculating their radius of curvature. It provides the test principle, specimen preparation and measurement procedure, and notes the relationship with other ISO tile property standards (for example ISO 13006 for product requirements).

Scope

ISO 10545-20:2022 specifies a laboratory procedure to determine the out-of-plane deflection of ceramic tile specimens and to calculate the corresponding radius of curvature. The method is intended for use when curvature/warpage is a relevant characteristic for product assessment, quality control or specification. The standard also cross-references other tile test methods where relevant.

Key topics and requirements

• Test principle: measurement of tile deflection under specified support/measurement conditions to derive radius of curvature.
• Specimen preparation and orientation requirements to ensure repeatable deflection results.
• Measurement procedure and calculation method to convert measured deflection into a radius of curvature.
• Normative references used in the procedure (for example ISO 10545-4 for rupture/breaking strength methods and ISO 48‑2 for relevant hardness measurements where referenced).
• Reporting requirements and test accuracy considerations for use in specification and compliance records.

Typical use and users

Primary users include ceramic tile manufacturers (for production control and product development), independent testing laboratories, certification bodies, standards writers and specification professionals (architects, engineers and procurement teams) who need objective measurements of tile warp or curvature for acceptance criteria, warranty assessment and design fit checks. National standards bodies and conformity assessment organizations also adopt the method into regional standards packages.

Related standards

ISO 10545-20 is one part of the ISO 10545 multi-part test series for ceramic tiles (see related parts such as ISO 10545-1 to ISO 10545-19 and newer parts in the series). It is referenced alongside product requirement standards such as ISO 13006 and normative test references including ISO 10545-4 (modulus of rupture/breaking strength) and ISO 48-2 (hardness). The method is often published in harmonized/adopted form as EN ISO 10545-20 / BS EN ISO 10545-20 and equivalent national adoptions.
