Figure 1 — Individual hardwood board 3.2 solid pre-assembled hardwood board wide and generally long solid (single-layer) hardwood element, pre-assembled from several strips in length and width by dovetailing, edge gluing and end jointing which has parallel sides, is machined to a regular thickness and profile(s) with profiled edges and ends, and is capable of being assembled with other analogous elements (see Figure 2)

EN 13629:2012 (E) 6 4 Specific product requirements 4.1 Wood species A list of the most commonly used hardwood species for wood flooring as described in this standard is given in Annex A. 4.2 Finishing The product may be delivered with a factory applied surface coating which allows the product to be taken into use immediately after installation. The surface treatment used and any artificial change of the natural wood colour shall be stated in the product description. 4.3 Appearance 4.3.1 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 solid wood flooring 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). Bio deterioration, permitted only for certain appearance classes (see table 1 to 4) 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 face shall include all the visible surface of the element.
Any continuous glue joint which allows renovation without significantly changing the appearance or the functional characteristics is acceptable. 4.3.2 Classification The class shall be specified. The decorative appearance of each species will vary with class. NOTE It should be noted that some classes allow many natural characteristics. This fact should be taken into account when specifying decorative appearance. SIST EN 13629:2012
