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. 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 9167-1 was prepared by Technical Committee
ISO/TC 34, Agricultural food products, Sub-Committee SC 2, Oleaginous
seeds and fruits.
ISO 9167 consists of the following Parts, under the general title
Rapeseed - Determination of glucosinolates content:
-
Part 1: Method using high-performance liquid chromatography
-
Part 2: Method using X-ray fluorescence spectrometry
