Full title and description

ISO 10545-12:1995 — Ceramic tiles — Part 12: Determination of frost resistance. Specifies a laboratory method to determine the frost resistance of ceramic tiles intended for use in freezing conditions in the presence of water.

Abstract

This part of ISO 10545 defines the test procedure used to assess how ceramic tiles behave when saturated with water and exposed to repeated freeze–thaw cycles. The method includes impregnation of specimens (vacuum impregnation), controlled freeze–thaw cycling and post‑test evaluation by visual inspection and comparison of water absorption before and after the test to quantify damage and degradation.

General information

• Status: Published; standard under periodic systematic review (confirmed as current in ISO’s review cycle).
• Publication date: November 1995 (Edition 1, 1995).
• Publisher: International Organization for Standardization (ISO), prepared by ISO/TC 189 (Ceramic tiles).
• ICS / categories: 91.100.23 (Ceramic tiles).
• Edition / version: Edition 1 (1995). Technical corrigendum issued (1997) for some procedural clarifications.
• Number of pages: Short technical publication (ISO metadata lists the document as a brief part — ISO listing indicates 2 pages in its metadata record; some catalogs list longer commercial reproductions).

Scope

This standard applies to all types of ceramic tiles intended to be used where they may be exposed to freezing conditions while wet (for example outdoor paving, terraces, façades). It specifies the laboratory test to determine a tile’s resistance to frost when water is present in the tile pores or on the surface, including sample preparation, impregnation, freeze–thaw cycling, temperature control and criteria for inspection and reporting.

Key topics and requirements

• Sample preparation and minimum specimen area/number requirements for representative testing.
• Impregnation procedure (vacuum impregnation to ensure water penetration into pores prior to freezing).
• Freeze–thaw cycle parameters (typical practice: cycles between about +5 °C and −5 °C, controlled rates and dwell times, with a minimum number of cycles specified — e.g., 100 cycles in common implementations/corrigendum guidance).
• Temperature monitoring and control requirements for the test environment and specimens.
• Measurements of water absorption before and after testing (E1 and E2 calculations) and visual assessment of surface and edge damage.
• Reporting requirements: identification of tiles tested, number of specimens, test conditions, E1/E2 results, description of defects and number of damaged tiles.

Typical use and users

Used by ceramic tile manufacturers for product development and quality control, independent testing laboratories for conformity and classification, specifiers and architects verifying suitability of tiles for exterior or freeze‑exposed installations, and certification bodies assessing compliance with contractual or regulatory requirements.

Related standards

ISO 10545-12 is one part of the ISO 10545 series (Ceramic tiles). Other relevant parts in the series cover sampling and acceptance, dimensions and surface quality, water absorption and bulk density, mechanical and abrasion tests, thermal properties, crazing, chemical resistance, stain resistance, and more — these parts are commonly referenced together when specifying or testing ceramic tiles (for example ISO 10545-1, -2, -3, -4, -6, -7, -8, -9, -11, -13, -14, etc.).

FAQ

Q: What is this standard?

A: ISO 10545-12:1995 is the ISO test method titled "Ceramic tiles — Part 12: Determination of frost resistance", which specifies how to assess a ceramic tile’s resistance to damage when saturated with water and exposed to freezing and thawing cycles in a laboratory setting.

Q: What does it cover?

A: It covers specimen preparation (including impregnation), the controlled freeze–thaw cycling procedure, measurement of water absorption before and after testing, visual inspection of defects, and the content required in test reports to document frost resistance performance.

Q: Who typically uses it?

A: Tile manufacturers, independent test laboratories, product certifiers, architects and specifiers who need to demonstrate or validate that a tile product is suitable for use in freezing/wet conditions.

Q: Is it current or superseded?

A: ISO’s metadata shows ISO 10545-12:1995 as a published part that has been subject to ISO’s periodic review and was confirmed in ISO’s review cycle (the ISO record indicates review/confirmation activity, including confirmation in 2021). A technical corrigendum was issued in 1997 to clarify procedural details; the 1995 edition remains the normative document listed by ISO. Users should always check with their national standards body or ISO for the latest status before relying on a standard for certification or regulatory purposes.

Q: Is it part of a series?

A: Yes — ISO 10545-12 is Part 12 of the ISO 10545 multi‑part series covering many test methods for ceramic tiles (sampling, dimensions, water absorption, mechanical and abrasion tests, thermal properties, chemical resistance, etc.).

Q: What are the key keywords?

A: Frost resistance, freeze‑thaw, vacuum impregnation, water absorption, ceramic tile testing, ISO 10545.
