DIN EN 13226:2009-09 EN 13226:2009 (E) 4 Introduction This Europ
20、ean Standard is one of a series of standards concerning wood flooring and wood panelling and cladding. This standard specifies the characteristics of solid parquet elements. It is based upon current dimensional standards within the industry and other characteristics together with functions which hav
21、e been verified by test. A large amount of knowledge exists about solid parquet elements 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 appear
22、ance of the parquet is mainly influenced by species, classification and the pattern. DIN EN 13226:2009-09 EN 13226:2009 (E) 5 1 Scope This European Standard specifies the characteristics of solid parquet elements with grooves and/or tongues for internal use as flooring. This standard is not applicab
23、le to panels made from elements for which a separate standard is in course of preparation. This standard covers elements with or without surface treatment. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、 A. 5.2 Appearance 5.2.1 General rules Tables 1 to 9 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 acco
35、rding 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 null, and null. A classification named “Free class“ is based on the principles laid out
36、 in Annex B. 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 from shake and the wood shall be sound. Any continuous glue joint which allows renovation without significantly changing the appearance or the funct
37、ional characteristics is acceptable. 5.2.2 Rules for the most commonly used species 5.2.2.1 Quercus spp. (oak) Rules for oak are given in Table 1. 1) The chamfering is visible when elements are assembled.
