BS EN 13228:2011EN 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 characteristics of solid w

20、ood 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 characteristics are attested by

21、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. BS EN 13228:2011EN 13228:2011 (E) 5 1 Scope This Euro

22、pean Standard specifies the characteristics of solid wood overlay flooring including blocks with an interlocking system for internal use as flooring. It applies to elements. This standard covers elements with and without surface coating. 2 Normative references The following referenced documents are

34、n 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

35、 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 classification differences, 3 % of the

36、 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 chamfering1)if any. The face shall be free fr

37、om 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.
