Introduction
This standard is one of a series of standards about wood flooring and wood panelling and cladding.
This standard specifies the characteristics of mosaic parquet. It is based upon current dimensional standards used in
the industry together with functions which have been verified by test.
A large amount of knowledge exists about mosaic parquet 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 appearance of the parquet floor is mainly influenced by species, classification and the pattern.

4.2 Appearance
4.2.1 General rules
Tables 1 to 3 define the classification relating to appearance rules for the face and for the non-visible parts (back and
edges) of a mosaic parquet finger of the most commonly used species for mosaic parquet 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). Biodeterioration is measured according to EN 1311.
A classification with three appearance classes is specified, designated , D and .
A classification named "Free class" is based on the principles laid out in Annex C.
The face shall include all the visible surface of the element.
The face shall be free of bore holes and the wood shall be sound. Growth rings as well as medullary rays are
permitted.
4.2.2 Rules for the most commonly used species
4.2.2.1 Quercus spp. (oak) and tropical hardwoods
Rules for oak and tropical hardwoods are given in Table 1.
