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 procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 28, Petroleum and related products, fuels
and lubricants from natural or synthetic sources.
This third edition cancels and replaces the second edition (ISO 3015:1992), which has been technically
revised. The main changes compared to the previous edition are as follows:
— extension of the scope to diesel fuels with up to 30 % (V/V) FAME and inclusion of paraffinic
diesel fuels;
— inclusion of digital contact thermometer;
— normative references in Clause 2 have been updated;
[1]
— bath and sample temperature ranges have been aligned with ASTM D2500 , changes in bath
temperature and the temperatures at which the test jars are moved to the batch with the next lower
temperature have over the years (1992 up to the time of publication of this document) not led to
observation of a bias versus test results obtained with the former edition;
— the precision for 'other products' has been removed as data to support it could not be obtained for
comparison;
— a bibliography has been added.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

1 Scope
This document specifies a method for the determination of the cloud point of petroleum products which
are transparent in layers 40 mm in thickness and have a cloud point below 49 °C, amongst which are
[2]
diesel fuels with up to 30 % (V/V) of fatty acid methyl ester (FAME) , paraffinic diesel fuels with up to
[3] [5]
7 % (V/V) FAME , 100 % FAME and lubricants.
NOTE For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction (φ) of
a material.

4 Principle
A sample is cooled at a specified rate and examined periodically. The temperature at which a cloud is
first observed at the bottom of the test jar is recorded as the cloud point.
5 Apparatus
5.1 Test jar, cylindrical, of clear glass, flat bottomed, 33,2 mm to 34,8 mm in outside diameter and
115 mm to 125 mm in height; the inside diameter of the jar may range from 30,0 mm to 32,4 mm, within
the constraint that the wall thickness be no greater than 1,6 mm.
See Figure 1 for more details. The jar shall be marked with a line to indicate a sample height
54 mm ± 3 mm above the inside bottom.
5.2 Temperature measuring device, one of the following.
5.2.1 Liquid-in-glass thermometers, as described in A.2.
5.2.2 Digital contact thermometer (DCT), meeting the requirements specified in A.1.
5.3 Cork, to fit
