This standard specifies the characteristics of multi-layer parquet. It is based upon current dimensional standards used in the industry and other characteristics together with functions which have been verified by test. A large amount of knowledge exists about multi-layer parquet and values for product characteristics are attested by long use and experience. It is therefore not necessary to have test results. For new products technical data will have to be verified by testing. The appearance of the parquet floor is mainly influenced by species, classification and the pattern.

Figures 2 and 3 are examples of types which are intended for patterned installation. Elements in Figure 3 are usually of smaller dimensions.

NOTEThe product is usually delivered with a factory applied surface coating which allows the product to be taken into use immediately after installation. 4.4 Appearance 4.4.1 General rules Tables 1 to 4 define the classification relating to appearance rules for the face and for the non-visible parts (back and edges) of an element of the most commonly used species for multi-layer parquet as defined in this standard. Features shall be measured according to EN 1310 (knots assessed according to the general method of 4.1 in EN 1310:1997). Biodeterioration is measured according to EN 1311. A classification with three appearance classes is specified, designated ?, and ?. A classification named « Free class » is based on the principles laid out in Annex B. The material used for the top layer shall be selected hardwood or softwood, fresh and sound without rot, fungus, mould or insect damage. There will be variations from strip to strip, but the total impression of the installed floor shall show a homogeneous character of each classification. To allow for unavoidable classification differences, 3 % of the strips in a batch may be from other classes. Any additional strips from other classes are allowed as long as the general impression of the floor is not disturbed. Multi-layer parquet with a mosaic-like pattern shall be classified according to EN 13488. 4.4.2 Classification rules for type 1, 2 and 3 parquet 4.4.2.1 Rules for the most commonly used species 4.4.2.1.1 Quercus spp. (oak) Rules for oak are given in Table 1.
