31、tory 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 classific
32、ation 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 i
33、n 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. Th
34、e 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 w
35、ill 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.
