Liquid petroleum products — Determination of hydrocarbon types — Fluorescent indicator adsorption method
The method specified applies to hydrocarbon types over the concentration ranges from 5 % (V/V) to 99 % (V/V) aromatic hydrocarbons, 0,3 % (V/V) to 55 % (V/V) olefins, and 1 % (V/V) to 95 % (V/V) saturated hydrocarbons in petroleum fractions that distill below 315 °C. Restrictions inherent in the method and the determination of precision may limit its application.

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, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(1 EC) 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 International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 3837 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubricants.
Annex A of this International Standard is for information only.

Introduction
The determination of the total volume percent [% (VW)] of saturates,
olefins and aromatics in Petroleum fractions is important in characterizing
the quality of Petroleum fractions as gasoline blending components and
as feeds to catalytic reforming processes, and in characterizing Petroleum
fractions and products from catalytic reforming and from thermal and
catalytic cracking as blending components for motor and aviation fuels.
This information is also important as a measure of the quality of aviation
turbine fuels.
