Full title and description

ISO 10545-12:1995 — Ceramic tiles — Part 12: Determination of frost resistance. Includes Technical Corrigendum 1 published in 1997 which makes minor amendments to the original 1995 text (subclauses amended as noted in the corrigendum).

Abstract

Specifies a laboratory method for determining the frost resistance of ceramic tiles intended for use in freezing conditions when exposed to water. After water impregnation, tiles are subjected to repeated freeze–thaw cycles and assessed for visual damage and changes in water absorption.

Scope

This part of ISO 10545 specifies a test method to determine whether ceramic tiles intended for outdoor or cold‑climate use will withstand freezing conditions in the presence of water. The method applies to all ceramic tiles where exposure to water followed by freezing may occur and provides criteria for assessing visual damage and changes in water absorption after prescribed freeze–thaw cycling.

Key topics and requirements

• Principle: water‑impregnate specimens, then submit them to repeated freeze–thaw cycles (tiles exposed on all faces) and inspect for damage and change in water absorption.
• Freeze–thaw cycling: cycles between approximately +5 °C and −5 °C with controlled ramp and dwell times; a minimum of 100 cycles is specified.
• Specimen requirements: test a minimum total area (commonly stated as 0.25 m²) and not fewer than 10 whole tiles; tiles must be free of pre‑existing relevant defects or such defects must be recorded.
• Impregnation and mass control: tiles are saturated with water before cycling (vacuum impregnation or immersion methods referenced in related parts); mass measurements before and after the test are used to calculate initial and final water absorption (E1 and E2) for reporting.
• Assessment: visual inspection for cracking, crazing, spalling, edge/corner damage and reporting of any physical deterioration and measured absorption changes; corrigendum 1997 makes small editorial/technical amendments (noted in subclauses referenced by ISO).

Typical use and users

Used by independent materials testing laboratories, ceramic tile manufacturers (quality control and product development), architectural and engineering specifiers, building product certifiers, and regulatory bodies assessing suitability of tiles for exterior paving, balconies, facades and other wet/freezing exposures. Test houses commonly offer this test as part of a tile technical report or conformity assessment.

Related standards

Part of the ISO 10545 series (test methods for ceramic tiles). Related and commonly referenced parts include ISO 10545-1 (sampling and acceptance), ISO 10545-2 (dimensions and surface quality), ISO 10545-3 (water absorption and density), ISO 10545-4 (breaking strength), ISO 10545-6/7 (abrasion), ISO 10545-8 (thermal expansion), ISO 10545-9 (thermal shock) and ISO 10545-13/14 (chemical and stain resistance). EN/BS variants (EN ISO / BS EN versions) often incorporate the same procedures; corrigenda for related parts were also issued in the late 1990s.

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." A Technical Corrigendum (ISO 10545-12:1995/Cor 1:1997) corrects minor points in the original text.

Q: What does it cover?

A: It covers a laboratory procedure to assess whether ceramic tiles will resist damage when saturated with water and subjected to repeated freeze–thaw cycles (exposure between about +5 °C and −5 °C for a minimum of 100 cycles), together with requirements for specimen selection, impregnation, mass measurements and visual assessment.

Q: Who typically uses it?

A: Tile manufacturers (for product qualification), independent test laboratories, architects and specifiers, and conformity assessment bodies evaluating tiles for exterior or cold‑climate applications. Test reports based on this method support product datasheets and performance claims.

Q: Is it current or superseded?

A: The ISO entry for ISO 10545-12:1995 shows the 1995 edition with Corrigendum 1 (1997) and that the record has been reviewed in ISO's maintenance cycle; ISO lists the edition and corrigendum as the published items (ISO bibliographic entries should be checked for any later revisions). For procurement or regulatory use, verify with your national standards body or the ISO catalogue for any newer revision after 1995/1997.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10545 series of test methods for ceramic tiles (multiple parts cover sampling, dimensions, water absorption, mechanical and chemical resistance, thermal properties, abrasion, etc.).

Q: What are the key keywords?

A: Frost resistance; freeze–thaw cycles; water impregnation; water absorption (E1, E2); ceramic tiles; ISO 10545-12; outdoor tile testing.
