19、ewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a techn
20、ical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
21、electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document
22、was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

It also incorporates ISO 10545-3:1995/Cor.1:1997.The ma
26、in changes compared to the previous edition are as follows: The impregnation of the samples is now only done by vacuum. The boiling method for impregnation of the samples has been removed.

In Table 2 some examples of different common sizes are reported. The number
36、of the specimens to be tested for each tile as well the number of tiles are function of the tile dimension. Tiles and relevant specimens shall not contain visible damage or cracks prior to testing and shall not have been previously tested. Any loose or contaminating material shall be removed. This i
37、ncludes any mesh, paper and adhesive that has been applied to mosaics.When the mass of each individual tile is below 50 g, a sufficient number of tiles shall be taken so that each test specimen reaches a mass of 50 g to 100 g. For those specimens, 6.2 is not applicable.Table 1 SamplingMaximum area A

Cutting of specimens shall consist of scoring and snapping, or sawing when impossible to score and snap with conventional tile-scoring equipment (as can be the
42、case with highly textured and structured porcelain tiles). Cutting may be performed at the factory following the sampling criteria described where the sample being cut is at least 10 cm bigger on each cut side. At the testing facility, cutting shall be done no more than four hours before the specime
43、ns are placed in the dryer. Specimens shall be kept clean with no contaminating material after cutting.6.2.2 Tiles less than or equal to 400 cm2Specimens shall be cut in half, within 1 cm. Specimens shall be cut perpendicular to the longest side if the specimen has unequal sides. Select one half at
