Price based on 10 pages ed without license from IHS Not for Resale Foreword ISo (the International Organization for Standardization) is a worldwide federation of national 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. International organizations, govern- mental and non-governmental, in liaison with Iso, also take part in the work. Draft international Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISo Council. They are approved in accordance with isO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 8002 was prepared by Technical Committee ISO/TC 108, Mechanicalvibrationand shock. Users should note that all International Standards'undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated.

This International Standard specifies a uniform method for reporting data to facilitate comparing and compiling data. This International Standard applies to original reports of measured data and to reports or other publications which The results of a measurement of random vibration are an assess, summarize, compare or compile measured data from estimate based on a sample. This International Standard original reports. specifies the analysis parameters to be reported so that the statisticai precision of the reported data can be determined. It is not applicable to the reporting of any form of transfer func- tion or other dynamic property of a system as derived from the The measured vibration on land vehicles is a function both of measured data. the vehicle and of external factors, such as the operating con ditions and the road or terrain profile.
