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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 20823 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.

INTERNATIONAL STANDARD ISO 20823:2003(E)

Petroleum and related products — Determination of the
flammability characteristics of fluids in contact with hot
surfaces — Manifold ignition test
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 International 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 test method to determine the relative flammability of fluids when
contacted with a hot metal surface at a fixed temperature, but it is also possible to gauge fluid ignition
temperatures by adjustment of the manifold temperature.
It is primarily used to assess the resistance to ignition of fire-resistant hydraulic fluids which are, by definition,
difficult to ignite.
It may be used with other types of more flammable fluids at lower surface temperatures, but this could
significantly increase the hazards of this procedure.
NOTE The procedure given in this International Standard is specified in ISO 12922:1999, Lubricants, industrial oils
and related products (class L) — Family H (Hydraulic systems) — Specifications for categories HFAE, HFAS, HFB, HFC,
HFDR and HFDU.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

ISO 3170:— , Petroleum liquids — Manual sampling
3 Principle
A 10 ml test portion of fluid is dropped from a predetermined height and at a specified rate, onto a tube heated
to 700 °C, or another temperature in a series. The resulting spray is examined for flash or burn, both on the
tube and after dripping from the tube.
