It supersedes BS 6913-3:1989 which is withdrawn. The UK participation in its preparation was entrusted by Technical Committee B/513, Construction equipment and plant, and site safety, to Subcommittee B/513/1, Earth-moving machinery (International), which has the responsibility to: aid enquirers to understand the text; - present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; - monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled"International Standards Correspondence Index", or by using the “Find" facility of the BSI Standards Electronic Catalogue.
