The ISO 10545-1 standard describes the rules for blending, sampling, inspection and acceptance or rejection of ceramic tiles.

The ISO 10545-2 standard describes the dimensional properties (length, width, thickness, flatness of edges, rectangularity, surface flatness) and methods for determining the surface quality of ceramic tiles. Tiles with an area of ​​less than 4 cm2 are excluded from measurements of length, width, flatness of edges, rectangularity, and surface flatness. When measuring the length, width, flatness of the edges, rectangularity, it is intended to ignore spacers and glazing drops and other irregularities on the edges if these are subsequently hidden at the joints after fixing (installation). The flatness of the sides refers to the deviation from the flatness of the side center in the plane of the tile.

The ISO 10545-3 standard describes a method for determining the water absorption, apparent porosity, apparent relative density and bulk density of ceramic tiles. This method applies to the classification of tiles and product features.

The ISO 10545-4 standard describes a test method for determining the modulus of rupture and breaking strength of all ceramic tiles. The ISO 13006 standard provides property requirements for tiles and other useful information about these products. The breaking load refers to the force required to cause the test specimen to break, as read from the manometer. The breaking strength is the force obtained by multiplying the breaking load by the ratio of the span between the support bars / the width of the test specimen. The fracture coefficient expresses the calculated breaking strength divided by the square of the minimum thickness along the broken edge.

The ISO 10545-5 standard describes a test method for determining the impact resistance of ceramic tiles by measuring the aging coefficient. The aging coefficient between two impact bodies is the relative speed of movement divided by the relative speed of approach.

The ISO 10545-6 standard describes a test method for determining the deep abrasion resistance of all unglazed ceramic tiles used in floor coverings.

The ISO 10545-7 standard describes a method for determining the resistance to surface wear of all glazed ceramic tiles used for flooring.

The ISO 10545-8 standard describes a test method for determining the linear thermal expansion coefficient of ceramic tiles.

The ISO 10545-9 standard describes a test method for determining the resistance of all ceramic tiles to thermal shock under normal conditions of use. Depending on the water absorption of the tiles, different procedures (immersion or non-immersion tests) are used, unless otherwise agreed. The ISO 13006 standard provides property requirements for tiles and other useful information about these products.

The ISO 10545-10 standard describes a method for determining the moisture expansion of ceramic tiles. Moisture expansion refers to the proportional accelerated expansion resulting from prolonged immersion of reheated tiles in boiling water.

The ISO 10545-11 standard describes a test method for determining the crack resistance of all glazed ceramic tiles, except where cracking is a natural decorative feature of the product. ISO 13006 Ceramic tiles - The standard for definitions, classification, properties and marking provides the specification requirements for tiles and other useful information regarding these products. Crack refers to a crack that appears as a thin hairline limited to the glazed surface of a tile.

The ISO 10545-12 standard describes a method for determining the frost resistance of all ceramic tiles intended for use in freezing conditions where water is present.

The ISO 10545-13 standard describes a test method for determining the chemical resistance of ceramic tiles at room temperature. This method applies to all types of ceramic tiles.

The ISO 10545-14 standard describes a method for determining the resistance of a suitable surface of ceramic tiles to stains.

The ISO 10545-15 standard describes a method for the determination of lead and cadmium emitted from the surface of ceramic tiles.

The ISO 10545-16 standard describes a method for using color measuring instruments to measure small color differences between solid colored ceramic tiles designed to be of uniform and consistent colour. This method allows determining a maximum acceptable value, which depends only on the closeness of the match and not on the nature of the color difference. This standard does not apply to color variants produced for artistic purposes. This test method may only be applied where minor color differences between solid colored tiles in a specification or agreement are significant. Chroma refers to the color property defined as a deviation from gray with the same lightness. The further a color deviates from gray, the higher the chroma. Lightness refers to the parameter that relates the color to the continuous gray scale between white and black. The CIE 1976 L*a*b* value represents the value calculated from the measured spectral reflectance curves given in the CIE 015 standard.

The ISO 10545-18 standard describes a test method for determining the light reflectance value (LRV) of ceramic tiles, including mosaic tiles. This test method can be applied to monochrome, multi-colored and inhomogeneous shade tile surfaces, including flame effect, mottled or textured tiles with different types of finishes. A plain colored surface means a surface with color integrity and the same shade value, and a multi-colored surface means a surface consisting of different areas of different colors when viewed from a distance of 3 m, or a surface consisting of small color spots that appear as one color when viewed from a distance of 1 m. The light reflectance value (LRV) refers to the value equivalent to the CIE tristimulus value Y, also known as the luminance factor. LRV is expressed as a percentage.
