SAMPLING: Sampling and the basis for acceptance complied with the requirements of ISO 10545-1.
COMPLIANCE: When tested according to the relevant method indicated in parenthesis, the above results all conform 10 the requirements of the Manufacturing Standard.
REMARKS ON SLIP RESISTANCE CLASSIFICATIONS (AS/NZS4586:1999): Tiles tested to AS/NZ 4586:1999 'Slip resistance classification of new pedestrian surface materials'. The slip resistance of surface may change with use either becoming more slippery because of natural polishing, or less due to abrasion and roughening of the surface. The presence of dirt or contaminants may make surfaces more slippery, as can poor maintenance practices.
CLASSIFICATIONS: In order to interpret the classifications, please refer to Standards Australia Handbook 197 'An Introductory guide to the Slip resistance of pedestrian surface materials' which recommends minimum classifications for a wide variety of locations. It Is important to realise that test results obtained on unused factory-fresh samples may not be directly applicable in service, where propriety surface coatings, contamination, wear and subsequent cleaning all influence the behavior of the pedestrian surface.
REMARKS ON THE MOISTURE EXPANSION OF CERAMIC TILES: The majority of glazed and unglazed tiles have negligible natural moisture expansion that does not contribute to tiling problems when tile are correctly fixed. However, with unsatisfactory fixing practices and in certain climatic conditions, natural moisture expansion may aggravate problems, especially when tiles are directly fixed to inadequately aged concrete substances. Source: ISO 10545-10.
NOTE: Regular Quality Control Audits ensure continuing compliance to the Standard although minor variations can occur in some values from batch to batch, within the allowable tolerances. These specifications will be re-issued if major variations occur, for example with the installation of new manufacturing equipment. |
