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. 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

The committee responsible for this document is ISO/TC 28, Petroleum products and lubricants, (WG 9) in
conjunction with Technical Committee ISO/TC 35, Paints and varnishes.
This second edition cancels and replaces the first edition (ISO 9038:2002), which has been technically
revised.
The main technical changes are the inclusion of 3 reference materials for verification in Annex B.

ISO 9038:2013(E)
Introduction
A product with a flash point within a given range can continue to burn after initial ignition, while a
similar product, although it has a similar flash point, may not. This International Standard describes a
method for discriminating between those products that sustain combustion and those that do not.
The method determines whether a flammable product, when maintained at a selected test temperature,
gives off sufficient flammable vapour to cause ignition when an ignition source is applied, and continues
to generate sufficient vapour to burn when the ignition source is removed.
This test method does not determine the flash point of the product under test but, by means of a pass/fail
procedure, merely determines if it sustains combustion (fail) at a selected test temperature, as can be
required to comply with laws or regulations relating to the storage, transport and use of flammable
products. Before performing this test, it will normally be necessary to determine either the actual flash
point of the material or the temperature range in which the flash point is located.
The apparatus specified in this International Standard enables a result to be determined by a rapid
procedure using a small test portion (2 ml).
INTERNATIONAL STANDARD ISO 9038:2013(E)
Determination of sustained combustibility of liquids
WARNING — The use of this International Standard may involve hazardous materials, operations
or 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 to determine the applicability of regulatory
limitations prior to use.
1 Scope
This International Standard specifies a pass/fail procedure, at temperatures up to 100 °C, to determine
whether or not a liquid product, that would be classified as “flammable” by virtue of its flash point, has the
ability to sustain combustion at the temperature or temperatures specified in the appropriate regulations.
NOTE 1 Many national and international regulations classify liquids as presenting a flammable hazard on the
basis of their flash point, as determined by a recognized method. Some of these regulations allow a derogation if
the substance cannot “sustain combustion” at some specified temperature or temperatures.
NOTE 2 In connection with the United Nations recommendations on the Transport of Dangerous Goods as
well as with the Globally Harmonized System of Classification and Labelling of Chemicals, and also with derived
[1][2]
national/EC regulations, temperatures of 60,5 °C and 75,0 °C are specified for this test.
The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents,
petroleum or related products and adhesives, which have a flash point. It is not applicable to painted
surfaces in respect of assessing their potential fire hazards.
NOTE 3 This test method can be used, in addition to test methods for flash point, in assessing the fire hazard
of a product.
NOTE 4 Particular care needs to be taken in translating results from this test method to large scale (real life)
situations, as liquids in large quantities may not behave in the same way as small samples.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
sustained combustibility
behaviour of a material, under specified test conditions, whereby its vapour can be ignited by an ignition
source and, after ignition, sufficient flammable vapour is produced for burning to continue for at least
15 s after the source of ignition has been removed
ISO 9038:2013(E)
3.2
flash point
lowest temperature, as measured in the prescribed manner, of a test portion, corrected to a barometric
pressure of 101,3 kPa, at which application of an ignition source causes the vapour of the test portion
to ignite momentarily and the flame to propagate across the surface of the liquid, under the specified
conditions of test
4 Principle
A test portion of specified volume is introduced into the test cup, which is maintained at the test
temperature. After a specified time an ignition source is applied.
