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 3016:1994), which has been technically
revised. The main changes compared to the previous edition are as follows:
— inclusion of digital contact thermometer in 5.2.1;
— update of normative references in Clause 2;
[1]
— chemicals and mixtures moved from former Clause 4 to Annex B (alignment with ISO 3015 );
[2]
— bath and sample temperature ranges have been aligned with ASTM D97 , 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 (1994 up to the time of publication of this document) not led to
observation of a bias versus test results obtained with the former edition;
— option for using automatic apparatus has been removed as being non-applicable;
— automated apparatus no longer being addressed as its use is at the discretion of the laboratory and
the precision does not apply to that equipment;
— addition of sampling instructions in Clause 6;
[2]
— alignment of Clause 9 on precision, with ASTM D97 and introduction of Annex C;
— addition of a Bibliography.
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.
