DIN EN 13228:2011-08 EN 13228:2011 (E) 4 Introduction This standard is one of a series of standards about wood flooring and wood panelling and cladding. This standard specifies the charac
24、teristics of solid wood flooring elements. 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 solid wood flooring elements and values for product characterist
25、ics 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 wood flooring is mainly influenced by species, classification and the pattern. DIN EN 13228:2011-08 EN 13228:201

38、les 1 to 6 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
39、 to the general method of 4.1 in EN 1310:1997). Bio deterioration is measured according to EN 1311. A classification with three appearance classes is specified, designated null, and null. A classification named “Free class“ is based on the principles laid out in Annex B. To allow for unavoidable cla
40、ssification differences, 3 % of the strips in a batch may be other classes. Any additional strips from other classes are allowed as long as the general impression of the floor is not disturbed. The face shall include all the visible surface of the element. It shall therefore extend to the chamfering
41、1)if any. The face shall be free from shake and the wood shall be sound. Any continuous glue joint which allows renovation without significantly changing the appearance or the functional characteristics is acceptable. 1) The chamfering is visible when elements are assembled.
