EN 13227:2017 (E) 4 Introduction This European Standard is one of a series of standards about wood flooring and wood panelling and cladding. This European Standard specifies the characteristics of solid lamparquet products including solid large lamparquet products. 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 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 be verified by testing. The appearance of the parquet is mainly influenced by species, classification and the pattern. SIST EN 13227:2018

Introduction
This European Standard is one of a series of standards about wood flooring and wood panelling and cladding.
This European Standard specifies the characteristics of solid lamparquet products including solid large
lamparquet products. 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 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 appearance of the parquet is mainly influenced by species, classification and the pattern.
