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 January 2007, and con

    19、flicting national standards shall be withdrawn at the latest by January 2007. This document supersedes EN 300:1997. The following principal modifications have been made: a) thickness ranges for board types OSB/2, OSB/3 and OSB/4 have been extended; b) requirements for moisture resistance have been a

    20、dapted; c) requirements for the marking of boards have been simplified, taking account of the fact that EN 13986 now describes the detailed requirements for CE marking of boards for use in construction; d) former Annexes E (list of approval numbers for option 2 board types with certain adhesives or

    21、adhesive systems) and F (A-deviations) have been deleted. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Den-mark, Estonia, Finland, France, Ge

EN 300:20065 1 Scope This European Standard applies to Oriented Strand Boards (OSB). It defines

    23、terms, establishes a classification and specifies requirements. The values listed in this European Standard relate to product properties but they are not characteristic values to be used in design calculations. NOTE Test methods for determination of mechanical properties for structural purposes are

    24、given in EN 789. Determination of characteristic values of mechanical properties and density for structural purposes is given in EN 1058. Design characteristic values for OSB are given in EN 12369-1. Information on supplementary properties is given in Annex C. 2 Normative references The following re
