Test for sustained combustibility of liquids (ISO 9038:2002)
The standard describes a pass/fail procedure for use with paint and related products to determine whether or not a product has the ability to sustain combustionunder specified conditions.
Prüfung der Weiterbrennbarkeit von Flüssigkeiten (ISO: 9038:2002)
In vielen nationalen und internationalen Vorschriften wird die Entzündungsgefahr von Flüssigkeiten nach ihrem mit einem anerkannten Verfahren bestimmten Flammpunkt klassifiziert. Einige dieser Vorschriften lassen eine Erniedrigung der Gefahrenstufe zu, wenn die Flüssigkeit bei einer bestimmten Temperatur oder bei bestimmten Temperaturen nicht weiterbrennt. Diese Internationale Norm legt ein Ja/nein-Verfahren fest, mit dem bestimmt wird, ob ein flüssiges Produkt, das auf Grund seines Flammpunktes als "entzündlich" eingestuft würde, bei der/den in den betreffenden Vorschriften angegebenen Temperatur/en selbstunterhaltend weiterbrennen kann oder nicht.
ANMERKUNG 1 In den Empfehlungen der Vereinten Nationen zum Transport von gefährlichen Gütern sind Temperaturen von 60,5 °C bis 75,0 °C festgelegt.
Das Verfahren ist anwendbar bei Gemischen wie Beschichtungsstoffe (einschließlich wasserverdünnbarer Beschichtungsstoffe), Lackbindemittel, Lösemittel, Mineralöl- oder ähnliche Produkte, die einen Flammpunkt haben. Es ist nicht anwendbar zum Beurteilen der Feuergefährlichkeit von flüssigen Beschichtungen.
ANMERKUNG 2 Dieses Prüfverfahren für das Weiterbrennen kann zusätzlich zum Prüfverfahren für den Flammpunkt zum Beurteilen der Feuergefährlichkeit eines Produktes eingesetzt werden. Besondere Vorsicht ist beim Übertragen von Ergebnissen aus Versuchen im Labor auf Verhältnisse in der Praxis geboten, da sich große Mengen von Flüssigkeiten anders verhalten können als kleine Proben.
Essai de combustion entretenue de liquides (ISO 9038:2002)
De nombreux règlements nationaux et internationaux classent les liquides présentant un risque d'inflammabilité sur la base de leur point d'éclair, déterminé par une méthode reconnue. Certains de ces règlements autorisent une dérogation si le produit concerné ne peut pas «entretenir la combustion» à une ou plusieurs températures spécifiées. La présente Norme internationale spécifie une méthode «tout ou rien» pour déterminer si un produit liquide, qui serait classé comme «inflammable» du fait de son point d'éclair, a ou n'a pas la capacité d'entretenir une combustion à la température ou aux températures spécifiées dans les règlements pertinents.
Le mode opératoire est applicable aux peintures (y compris les dispersions à l'eau), vernis, liants, solvants, produits pétroliers ou apparentés et aux adhésifs, qui ont un point d'éclair. Elle n'est pas applicable aux surfaces peintes en ce qui concerne leur comportement au feu.

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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO9038 was prepared by Technical Committee ISO/TC35, Paints and varnishes,
Subcommittee SC 9, General test methods for paints and varnishes.
It cancels and replaces ISO/TR 9038:1991, which has been technically revised.
Annexes A and B form a normative part of this International Standard.

Introduction
A product with a flash point within a given range may 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, after ignition under controlled laboratory conditions and subsequent removal of the
flame, sustain combustion and those which do not.
The method determines whether a flammable product, when maintained at a selected test temperature and under
the conditions of test, gives off sufficient flammable vapour at this temperature to cause ignition when an external
source of flame is applied in a standard manner, and continues to generate sufficient vapour to burn when the ignition
source is removed.
This method of test 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 at a selected test temperature, as may 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 (2ml).

INTERNATIONAL STANDARD ISO 9038:2002(E)
Test for sustained combustibility of liquids
WARNING—The use of this International Standard may involve hazardous materials, operations or
equipment. This standard does not purport to address all of the safety problems, if any, associated with its
use. It is the responsibility of the user of this standard to establish appropriate safety and health practices
and to determine the applicability of regulatory limitations prior to use.
1 Scope
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. This International Standard specifies a
pass/fail procedure 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 In the United Nations Recommendations on the Transport of Dangerous Goods, temperatures of 60,5 C and 75,0 C
are specified.
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 2 This test method can be used in addition to the test method for flash point in assessing the fire hazard of a product.
Particular care needs to be taken in translating results from small-scale tests to large-scale (real-life) situations, as liquids in large
quantities may not behave in the same way as small samples because geometry and the surface-to-volume ratio affect rates of
heat transfer and evaporation from the surface.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC

3.1
sustained combustibility
the behaviour of a material, under specified test conditions, whereby its vapour can be ignited by an external ignition
source and, after ignition, sufficient flammable vapour is produced for burning to continue after the source of ignition
has been removed
3.2
flash point
the lowest temperature 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, under the specified conditions of test
4Principle
A specified volume of sample is introduced into a concave depression, the test portion well, in a metal block that is
maintained at the test temperature. After a specified time a test flame is applied.
The ability of the product to sustain combustion is assessed on the basis of its ability to ignite, when exposed to a test
flame, and whether it continues to burn after the standard flame has been removed, under the specified conditions of
test.
