Foreword
This document (EN 634-2:2007) 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text or by endorsement, at the latest by August 2007, and conflicting national standards shall be withdrawn at
the latest by August 2007.
This document supersedes EN 634-2:1996.
The principal modifications introduced by this standard consist of a revision of the product marking
requirements, clarification that external control in the factory is carried out according to EN 326-2, and
clarification that inspection of an isolated lot of panels may be carried out according to EN 326-3.
This standard is one of a series specifying requirements for cement-bonded particleboards:
— EN 634-1, Cement-bonded particleboards — Specification — Part 1: General requirements;
— EN 634-2, Cement-bonded particleboards — Specifications — Part 2: Requirements for OPC bonded
particleboards for use in dry, humid and external conditions.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and United Kingdom.

1) Humid conditions are defined in terms of service class 2 of EN 1995-1-1 which is characterized by moisture content in
the material corresponding to a temperature of 20 °C and a relative humidity of the surrounding air exceeding 85 % for
only a few weeks per year. Boards of this type are suitable for use in biological hazard classes 1 and 2 of EN 335-3.
2) External conditions are defined in terms of service class 3 of EN 1995-1-1. Boards of this type are suitable for use in
biological hazard classes 1, 2, 3 and 4 of EN 335-3.
