7、This British Standard has been prepared under the direction of the Technical Sector Board for Building and Civil Engineering and is the English language version of EN633:1993, Cement-bonded particleboards Definition and classification, published by the European Committee for Standardization (CEN). E

8、N633 was produced as a result of international discussions in which the UK took an active part. This standard has no equivalent in BS5669-4:1989 although the definition of cement-bonded particleboard is technically equivalent to2.2 of that standard. This standard together with a number of other ENs

9、will form a comprehensive series of standards in the field of wood-based panels. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself
