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, 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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 responsible for identifying any or all such patent rights.
ISO 80000-8 was prepared by Technical Committee ISO/TC 12, Quantities, units, symbols, conversion factors,
in collaboration with IEC/TC 25, Quantities and units, and their letter symbols.
This first edition cancels and replaces the second edition of ISO 31-7:1992 and ISO 31-7:1992/Amd.1:1998.
The major technical changes from the previous standards are the following:
— the presentation of numerical statements has been changed;
—the special remarks in the Introduction have been changed;
—the normative references have been changed;
— some quantities have been added to the list of quantities and some quantities have been deleted.
This corrected version of ISO 80000-8:2007 incorporates the following corrections.
— 0.3.1 e) The sentence was reworded.
— 8-3.b In the definition, the sign “=” was replaced by the sign “:=” after “dec”.
— 8-18 In the definition and in the remarks, the subscript “f” was deleted.
In the definition, “frequency-weighted” was deleted.
— 8-22 In the definition and in the remarks, the subscript “ft” was deleted.
In the definition, “frequency- and time-weighted” was deleted.
In the remarks, “, or both” was added at the end of the first line.
In the remarks, “and/or specific frequency bands” was changed to “or specific frequency bands or
both” in the second line.
— 8-23 In the definition, “is” was added after “reference value”.
— 8-24 In the definition, “is” was added after “reference value”.
ISO 80000 consists of the following parts, under the general title Quantities and units:
