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).

Introduction
This document describes an automated method for the determination of the cloud point, based on the
[2]
manual determination technique described in ISO 3015 . In parallel with the revision of the manual
method, the scope has been extended to new fuels.
INTERNATIONAL STANDARD ISO 22995:2019(E)
Petroleum products — Determination of cloud point —
Automated step-wise cooling method
WARNING — The use of this document can involve hazardous materials, operations and
equipment. This document does not purport to address all of the safety problems associated
with its use. It is the responsibility of users of this document to take appropriate measures to
ensure the safety and health of personnel prior to application of this document and to fulfil
other applicable requirements for this purpose.
1 Scope
This document specifies a method to determine cloud point using a step-wise cooling technique that is
executed by means of automated equipment types with optical detection mode.
The method is applicable to distillate fuels, fatty-acid methyl esters (FAME) and paraffinic diesel fuels,
including blends thereof, as well as those containing flow-improvers or other additives, intended for use
in diesel engines and domestic heating installations.
The method can be applied to other products such as vegetable oils or lubricants, but these kinds of
products have not been evaluated during the interlaboratory study (ILS), no precision data are available.
