EN 2326 was produced as a result of international discussion in which the UK took an active part. A British Standard does not purport
9、 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 confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cove
