41、 All rights reserved ISO 10848-1:2017(E)ForewordISO (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 bod

42、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote

43、chnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO

44、 documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held resp

45、onsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given

48、 with the following changes:a) extension to field measurements;b) extension to building service equipment;c) normalized direction-averaged vibration level difference for junctions between lightweight elements has been introduced;d) an assessment method for the decrease in vibration level with distan

49、ce has been introduced;e) transmission function measurements with a calibrated structure-borne sound source has been introduced;f) definitions of element types A and B to avoid issues with the terms “heavy” and “light” have been added.A list of all the parts in the ISO 10848 series can be found on the ISO website.
