2、having been prepared under the direction of the Sector Board for Building and Civil Engineering, was published under the authority of the Standards Board and comes into effect on 15 April 1998 BSI 05-1999 ISBN 0 580 29424 2 National foreword This British Standard reproduces verbatim ISO 7129:1997 an
3、d implements it as the UK national standard. It supersedes BS 6913-3:1989 which is withdrawn.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
4、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 UKinterests informed; monitor related international and European developments and promulgate them in
5、 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 enti

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. Complia

13、tional standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Intern
14、ational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical comm
15、ittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. International Standard ISO 7129 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 3, Operation
16、and maintenance. This third edition cancels and replaces the second edition (ISO 7129:1989), which has been technically revised. Annex A forms an integral part of this International Standard.

18、tor-dozers, graders and scrapers, as defined in ISO6165, taking interchangeability into consideration. NOTESome values in inches in this International Standard are not equivalent to the corresponding values in millimetres because widely used values have been adopted. 2 Normative reference The follow
19、ing standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encoura
20、ged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
