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.
The main task of technical committees is to prepare International Standards, but
in exceptional circumstances a technical committee may propose the publication of
a Technical Report of one of the following types:
— type 1, when the required support cannot be obtained for the publication of
an International Standard, despite repeated efforts;
— type 2, when the subject is still under technical development or where for any
other reason there is the future but not immediate possibility of an agreement
on an International Standard;
— type 3, when a technical committee has collected data of a different kind from
that which is normally published as an International Standard (“state of the
art”, for example).
Technical Reports of types 1 and 2 are subject to review within three years of
publication, to decide whether they can be transformed into International
Standards. Technical Reports of type 3 do not necessarily have to be reviewed until
the data they provide are considered to be no longer valid or useful.
ISO/TR 3666, which is a Technical Report of type 3, was prepared by Technical
Committee ISO/TC 28, Petroleum products and lubricants.
This second edition cancels and replaces the first edition (ISO/TR 3666:1977),
which has been technically revised.
Annex A and Annex B of this Technical Report are for information only.
