European foreword
This document (EN 622-4:2019) has been prepared by Technical Committee CEN/TC 112 “Wood-based
panels”, the secretariat of which is held by DIN.
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 December 2019, and conflicting national standards
shall be withdrawn at the latest by December 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 622-4:2009.
This European Standard is one of a series of standards specifying requirements for fibreboards. The
other parts of this series are listed in Clause 2 and in the Bibliography.
Compared with EN 622-4:2009 the following modifications have been made:
a) bending strength for thickness range > 36 mm reduced;
b) normative references updated;
c) editorially revised.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
1 Scope
This document specifies the requirements for softboards as defined in EN 316, with a density
3 3
from 230 kg/m to 400 kg/m .
The values listed in this document relate to product properties but they are not characteristic values to
be used in design calculations.
NOTE Panels which are intended for use exclusively as thermal insulating products are covered by EN 13171.
