Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national

standards may be obtained on application to the CEN Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation

under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the

official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,

France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,

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text or by endorsement, at the latest by August 2007, and conflicting national standards shall be withdrawn at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.
