The work of preparing International Standards is normally carried out through Iso a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non- governimental, 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 committees 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 7457 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 1, Test methods relating to machine performance. This second edition cancels and replaces the first edition (ISO 7457:1983), which has been technically revised. @ISO1997 All rights reserved.Unless otherwise specified,nopart ofthispublicationmaybe reproduced orutilized in anyform orbyanymeans,electronic ormechanical, includingphotocopying and microfilm, without permission in writing from the publisher.

This International Standard is applicable to all types of steerable wheeled earth-moving machinery. It is applicable irrespective of the type of steering used. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
