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. Esch 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. 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 Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 5164 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubricants.
This second edition cancels and replaces the first edition
(ISO 5164:1977), of which it constitutes a minor revision.

Introduction
The purpose of this International Standard is to accord official ISO Status
to a test procedure which is already used in a standardized form all over
the world. The procedure in question is published jointly by the Ameri-
tan Society for Testing and Materials (ASTM) and the UK Institute of
Petroleum (IP) as method ASTM D 2699.86/lP 237/69, Standard test
method for knock characteristics of motor fuels by the research method.
In publishing this International Standard, ISO recognizes that this
method is used in its original text in many member countries and that
the Standard equipment and many of the accessories and materials re-
quired for the method are obtain
