European foreword

This document (prEN 12369-3:2021) has been prepared by Technical Committee CEN/TC 112 “Wood-

based panels”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12369-3:2008.
This document is intended to be used in conjunction with EN 1995-1-1.

This European Standard is one of a series specifying characteristic values of wood-based panels for

structural design. The other parts of this series are listed in the Bibliography.

Annex A is informative.
Compared to EN 12369-3:2008 the following changes have been made:

a) modification of the thickness range and of the values for single-layer panels given at Table 2 in

conjunction with changes in EN 13353;

b) modification the thickness ranges and of the values for multi-layer panels given at Table 3 in

conjunction with changes in EN 13353;
c) editorial changes.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association.
