Ceramic Tile Classification & Requirements
AS 4662-2003 Ceramic tiles – Definitions, classification, characteristics and marking is the applicable Australian Standard to classify ceramic tiles and determine if a ceramic tile is of the best commercial quality (first quality). Ceramic tiles are classified according to their method of manufacture which is both dry pressed or extruded and their water absorption characteristics. The classification then determines the physical and chemical properties required when tested to AS 4459 Methods of sampling and testing ceramic tiles.
The suite of AS4459 test methods include:
| AS4459.1 Part 1: Sampling and basis of acceptance
AS4459.2 Part 2: Determination of dimensions and surface quality AS4459.3 Part 3: Determination of water absorption, apparent porosity, apparent relative density and bulk density AS4459.4 Determination of modulus of rupture and breaking strength AS4459.5 Determination of impact resistance by measurement of coefficient of restitution AS4459.6 Determination of resistance to deep abrasion for unglazed tiles AS4459.7 Determination of resistance to surface abrasion for glazed tiles AS4459.8 Determination of linear thermal expansion |
AS4459.9 Determination of resistance to thermal shock
AS4459.10 Determination of moisture expansion AS4459.11 Determination of crazing resistance for glazed tiles
AS4459.12 Determination of frost resistance AS4459.13 Determination of chemical resistance AS4459.14 Determination of resistance to stains AS4459.15 Determination of lead and cadmium given off by glazed tiles AS4459.16 Determination of small colour difference |
Safe Environments can assist ceramic tile manufacturers, construction companies and consumers by providing advice on ceramic tiling, including expert witness evidence for legal proceedings.
