Determination of sustained combustibility of liquids (ISO/DIS 9038:2024)
This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s) specified e.g. in regulations.
NOTE Many national and international regulations classify liquids as presenting a flammable hazard based on 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(s).
The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, that have a flash point. It is not applicable to painted surfaces in respect of assessing their potential fire hazards.
This test method is applicable, in addition to test methods for flash point, for assessing the fire hazard of a product.

Essai de détermination de la combustion entretenue de liquides (ISO/DIS 9038:2024)
Le présent document spécifie un mode opératoire, applicable jusqu'à 100 °C, qui vise à déterminer si un produit liquide, qui serait classé comme «inflammable» du fait de son point d'éclair, entretient une combustion à la température ou aux températures spécifiées, par ex. dans les règlements.
NOTE 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 la substance en question ne peut pas «entretenir la combustion» à une ou plusieurs températures spécifiées.
Cette méthode est applicable aux peintures (y compris peintures en phase aqueuse), vernis, liants, solvants, produits pétroliers ou apparentés et adhésifs, qui ont un point d'éclair. Elle n'est pas applicable aux surfaces peintes, eu égard à l'évaluation du danger d'incendie qu'elles présentent.
Cette méthode d'essai est applicable, en complément de celles qui portent sur le point d'éclair, à l'évaluation du danger d'incendie d'un produit.

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, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 139, Paints and varnishes, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 9038:2021), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Clauses 8.6 and 8.7 have been revised and Warnings added to give improved advice to the operator on
possible ignition and burning scenarios that can be met during the test.
Any feedback or questions on this document should be directed to the user’s national standards body. A

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, does not continue to burn. This document 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,
generates sufficient flammable vapour to cause ignition when an ignition source is applied and then
continues to generate sufficient vapour to burn when the ignition source is moved to the “off” position.
This test method does not determine the flash point of the product under test but, by means of a test
procedure, merely determines if it sustains combustion at a selected test temperature; this criterion can
be required to comply with laws or regulations relating to the storage, transport and use of flammable
products. Before performing this test, for safety and test optimization reasons, it is usual to determine either
the actual flash point of the material or know the temperature range in which the flash point is located.
The apparatus specified in this document enables a result to be determined by a rapid procedure using a
small test portion (2 ml).

1 Scope
This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid product,
that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s)
specified e.g. in regulations.
NOTE Many national and international regulations classify liquids as presenting a flammable hazard based on
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(s).
The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents,
petroleum or related products and adhesives, that have a flash point. It is not applicable to painted surfaces
in respect of assessing their potential fire hazards.
This test method is applicable, in addition to test methods for flash point, for assessing the fire hazard of a
product.
