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.
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 3675 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubricants, subcommittee SC 3, Static
petroleum measurement.
This third edition cancels and replaces the second edition (ISO 3675:1993),
of which it constitutes a Technical revision.
Annex A forms an integral part of this International Standard. Annex B is for
information only.

Crude petroleum and liquid petroleum products —
Laboratory determination of density — Hydrometer method
WARNING — The use of this International Standard may involve hazardous materials, operations and
equipment. This International Standard does not purport to address all of the safety problems associated
with its use. It is the responsibility of the user of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This International Standard specifies a method for the laboratory determination, using a glass hydrometer, of
the density at 15 °C of crude petroleum, liquid petroleum products, and mixtures of petroleum and non-
petroleum products normally handled as liquids and having a Reid vapour pressure (RVP) of 100 kPa or less.
This International Standard is suitable for determining the density of mobile transparent liquids. It can also be
used for viscous liquids by carrying out the determinations at temperatures above ambient using a suitable
liquid bath for temperature control. It can also be used for opaque liquids by reading the hydrometer scale
where the top of the meniscus meets the stem of the hydrometer and applying a correction from table 1
(see 11.2).
Since hydrometers are calibrated to read correctly at the specified temperature, scale readings made at other
temperatures are only hydrometer readings and not values of density at these other temperatures.
