BRITISH STANDARD

National foreword This British Standard is the UK implementation of EN ISO 17892-4:2016. It partially supersedes BS 1377-2:1990, specifically clause 9. The UK participation in its preparation was entrusted to Technical Committee B/526/3, Site investigation and ground testing. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. © The British Standards Institution 2016. Published by BSI Standards Limited 2016 ISBN 978 0 580 85381 4
