Diese Internationale Norm beschreibt Methode, für Mineralölprodukte den Flammpunkt und den Brennpunkt im offenen Tiegel nach C leveland zu bestimmen. Sie gilt für solche Mineralölprodukte, die einen Flammpunkt im offenen Tiegel über 79°C haben, mit Ausnahme von Heizöl und ähnlichen Produkten, die üblicherweise nach dem Verfahren im geschlossenen Tiegel nach ISO 2719 {1} geprüft werden.
ANMERKUNG Flampunkt und Brennpunkt sind Hinweisse aud die Fähigkeit von Substanzen, brennbare Gemische mit Luft unter definierten Bedingungen zu bilen. Sie sind nur zwei von vielen Eigenschaffen, die einen Beitrag lesiten können, um die Brand- und Explosionseigenschaften.
Détermination des points d'éclair et de feu - Méthode Cleveland a vase ouvert (ISO 2592:2000)
La présente Norme internationale prescrit une méthode pour la détermination des points d'éclair et de feu de produits pétroliers à l'aide de l'appareil Cleveland à vase ouvert. Elle s'applique aux produits pétroliers dont le point d'éclair en vase ouvert est supérieur à 79 °C, sauf les fuel oils, qui sont en général testés à l'aide de la méthode en vase clos décrite dans la norme ISO 2719 [1].
NOTE Les points d'éclair et de feu donnent une indication de la capacité d'un produit à constituer un mélange inflammable avec l'air dans des conditions contrôlées, ainsi que sa capacité à maintenir la combustion. Ce sont seulement deux des propriétés qui peuvent contribuer à l'évaluation globale de l'inflammabilité et de la combustibilité d'un matériau.

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 ISO 2592 was prepared by Technical Committee ISO/TC 28, Petroleum products and
lubricants.
This second edition cancels and replaces the first edition (ISO 2592:1973), which has been technically revised.
Annexes A and B form a normative part of this International Standard. Annex C is for information only.

INTERNATIONAL STANDARD ISO 2592:2000(E)
Determination of flash and fire points — Cleveland open cup
method
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 procedure for the determination of flash and fire points of petroleum
products using the Cleveland open cup apparatus. It is applicable to petroleum products having an open cup flash
point above 79 °C, except fuel oils, which are most commonly tested by the closed cup procedure described in
[1]
ISO 2719 .
NOTE Flash point and fire point are indications of the ability of a substance to form a flammable mixture with air under
controlled conditions, and then to support combustion. They are only two of a number of properties that may contribute towards
the assessment of overall flammability and combustibility of a material.
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
maintain registers of currently valid International Standards.
ISO 3170:1988, Petroleum liquids — Manual sampling.
ISO 3171:1988, Petroleum liquids — Automatic pipeline sampling.
3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
3.1
flash point
lowest temperature of the test portion, corrected to a barometric pressure of 101,3 kPa, at which application of a
test flame causes the vapour of the test portion to ignite and the flame to propagate across the surface of the liquid,
under the specified conditions of test
3.2
fire point
lowest temperature of the test portion, corrected to a barometric pressure of 101,3 kPa, at which application of a
test flame causes the vapour of the test portion to ignite and sustain burning for a minimum of 5 s under the
specified conditions of test

ISO 2592:2000(E)
4Principle
The test test cup is filled to a specified level with the test portion. The temperature of the test portion is increased
rapidly at first and then at a slow constant rate as the flash point is approached. At specified temperature intervals,
a small test flame is passed across the test cup. The lowest temperature at which application of the test flame
causes the vapour above the surface of the liquid to ignite is taken as the flash point at ambient barometric
temperature. To determine the fire point, the test is continued until the application of the test flame causes the
vapour above the test portion to ignite and burn for at least 5 s. The flash point and fire point obtained at ambient
barometric pressure are corrected to standard atmospheric pressure using an equation.
5 Reagents and materials
5.1 Cleaning solvent, for removal of traces of sample from the test cup and cover.
NOTE The choice of solvent will depend upon the previous material tested, and the tenacity of the residue. Low volatility
aromatic (benzene free) solvents may be used to remove traces of oil, and mixed solvents such as toluene-acetone-methanol
may be efficacious for the removal of gum-type deposits.
5.2 Verification liquids, as described in C.2.
5.3 Steel wool, any grade capable of removing carbon deposits without damage to the test cup.
6 Apparatus
6.1 Cleveland open cup apparatus, as specified in annex A.
If automated equipment is used, ensure that it has been established that the results obtained are within the
precision of this International Standard and that the test cup and test flame applicator conform to the dimensional
and mechanical requirements specified in annex A. If automated testers are used, the user shall ensure that all the
manufacturer's instructions for adjusting and operating the instrument are followed.
In cases of dispute, the flash point as determined manually shall be considered the referee test.
6.2 Shield, approximately 460 mm square and 610 mm high, and having an open front.
6.3 Thermometer, of the partial immersion type, conforming to the specification given in annex B.
NOTE Other types of temperature-measuring devices may be used, provided that they meet the requirements for accuracy
and have the same reponse as the thermometers specified in annex B.
6.4 Barometer, accurate to 0,1 kPa. Barometers pre-corrected to give sea level readings, such as those used at
weather stations and airports, shall not be used.
7 Preparation of apparatus
7.1 Location of apparatus
Place the apparatus (6.1) on a level and steady surface in a draught-free room (see notes 1 and 2 below). Shield
the top of the apparatus from strong light by any suitable means, to permit detection of the flash point.
NOTE 1 When draughts cannot be avoided, it is good practice to surround the apparatus with a shield.
NOTE 2 When testing samples which produce toxic vapours, the apparatus may be located in a fume hood with an individual
control of air flow, adjusted so that vapours can be withdrawn without causing air currents over the test cup.

ISO 2592:2000(E)
7.2 Cleaning the test cup
Wash the test cup with an appropriate solvent (5.1) to remove any traces of gum or residue remaining from a
previous test. Dry the test cup using a stream of clean air to ensure complete removal of the solvent used. If any
deposits of carbon are present, remove them by rubbing with steel wool (5.3).
7.3 Preparing the test cup
Before use, cool the test cup to at least 56 °C below the expected flash point.
7.4 Assembly of apparatus
Support the thermometer in a vertical position with the bottom of the bulb 6 mm from the bottom of the test cup, and
located at a point halfway between the centre and side of the test cup on a diameter perpendicular to the arc (or
line) of the sweep of the test flame, and on the side opposite to the test flame applicator.
NOTE The immersion line engraved on the thermometer will be 2 mm below the level of the rim of the test cup when the
thermometer is properly positioned. An alternative method is to gently lower the thermometer until it contacts the bottom of the
test cup, and then raise it 6 mm.
