Foreword
This European Standard (EN 14519:2005) has been prepared by Technical Committee CEN/TC 175 “Round
and sawn timber”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at
the latest by June 2006
This standard is one of a series of standards concerning solid wood panelling and wood flooring (including
parquet).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
In this standard the characteristics of solid softwood panelling and cladding are described on the basis of
individual elements.
1 Scope
This European Standard specifies the characteristics of solid wood panelling and cladding with tongue and
groove machined from the following most common European species of softwood: spruce/fir, pine, larch,
European Douglas Fir and maritime pine.
Products are intended for interior or exterior use.
NOTE Products sold in the European Economic Area should comply with prEN 14915.

5 Requirements
5.1 General
The softwood species shall be selected with regard to the appearance expected, the suitability for the
intended purpose and the general characteristics of the species itself. All requirements apply at the time of
production, unless the manufacturer states otherwise.
5.2 Appearance and finishing
5.2.1 General
Grading applies to the face only, unless otherwise specified. Machining requirements are covered in 5.4.4 and
apply to all grades of all species.
The measurement of features shall be in accordance with EN 1310. Concerning knots the general method
given in 4.1.1 of EN 1310:1997 applies.
The boards may be finished with surface coating. The grading shall be done before the coating.
5.2.2 Grading classes
Grading and the features for spruce (Picea spp.) / fir (Abies spp.), scots pine (P.sylvestris), larch (Larix spp.)
and European Douglas Fir (Pseudotsuga menziesii) are given in Table 1. Grading and the features for
Maritime Pine (Pinus pinaster) are given in Table 2.
