Determination of flash/no flash - Rapid equilibrium closed cup method (ISO 3680:2004)
ISO 3680:2004 specifies a method for the determination of the ability of paints (including water-borne paints), varnishes, paint binders, adhesives, solvents and petroleum and related products, when maintained at a selected test temperature within the range of - 30 degrees Celsius and 300 degrees Celsius, and under the conditions of test, to yield sufficient flammable vapour at this temperature to cause ignition on the application of a test flame in a standard manner. When used in conjunction with the flash detector (A.1.6), ISO 3680:2004 is also suitable to carry out a flash/no flash test on fatty acid methyl esters (FAME).
Bestimmung des Flammpunktes - Ja/Nein-Verfahren - Schnelles Gleichgewichtsverfahren mit geschlossenem Tiegel (ISO 3680:2004)
Diese Internationale Norm legt ein Verfahren fest, mit dem bestimmt werden kann, ob Beschichtungsstoffe (einschließlich wasserverdünnbare Beschichtungsstoffe), Bindemittel, Lösemittel, Mineralölprodukte und verwandte Erzeugnisse, so sie bei einer gewählten Prüftemperatur zwischen -30 °C und 300 °C nach festgelegtem Verfahren temperiert werden, bei dieser Temperatur genügend brennbare Dämpfe abgeben, um diese durch eine externe Prüfflamme, betätigt nach festgelegtem Verfahren, zu entzünden. Diese Internationale Norm ist auch geeignet bei Fettsäuremethylestern (FAME) die Entscheidung �Entzündbarkeit Ja/Nein' zu treffen, wenn der Detektor (A.1.6) benutzt wird.
Essai de point d'éclair de type passe/ne passe pas - Méthode rapide à l'équilibre en vase clos (ISO 3680:2004)
L'ISO 3680:2004 spécifie une méthode d'essai pour déterminer si des peintures (y compris les peintures à support aqueux), des vernis, des liants pour peintures, des adhésifs, des solvants, des produits pétroliers et des produits connexes, lorsqu'ils sont maintenus à une température d'équilibre comprise entre -30 °C et 300 °C, dans les conditions de l'essai, émettent suffisamment de vapeurs inflammables à cette température pour provoquer l'inflammation en présence d'une flamme d'essai présentée de manière normalisée. Lorsqu'elle est utilisée avec le détecteur d'éclair, l'ISO 3680:2004 convient aussi pour l'essai de point d'éclair de type passe/ne passe pas des esters méthyliques d'acide gras (EMAG).

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 3680 was prepared jointly by Technical Committees ISO/TC 28, Petroleum products and lubricants and
ISO/TC 35, Paints and varnishes.
This fourth edition cancels and replaces the third edition (ISO 3680:1983), which has been technically revised.

Introduction
This International Standard describes one of two closed cup equilibrium methods for carrying out a
flash/no flash test for paints, varnishes, paint binders, solvents, adhesives, petroleum and related products.
[4]
When selecting a method, it should therefore be read in conjunction with the second method, ISO 1516 .
When used in conjunction with the flash detector (A.1.6) this International Standard is also suitable for the
flash/no flash testing of fatty acid methyl esters (FAME).
In both ISO 3680 and ISO 1516, the test is only carried out when the material under test and the air/vapour
mixture above the material in the test cup are approximately in temperature equilibrium.
This test method does not determine the flash point of the product under test, but merely its behaviour at the
selected test temperature as may be required to comply with laws or regulations relating to the storage,
transport and use of flammable products. For this purpose, it is unnecessary to determine the exact flash
point, but it is necessary to determine whether or not flashing occurs at a given temperature.
The apparatus specified in this International Standard enables a similar test result to be determined using a
more rapid procedure and a smaller test portion (2 ml or 4 ml) than that required in ISO 1516. In addition, the
apparatus can be made portable to the extent of being suitable for on-site testing in addition to its more
normal use in laboratories.
Collaborative work (see [6] in the Bibliography) has shown that results obtained by these procedures are
comparable. The interpretation of flash point results obtained on solvent mixtures containing halogenated
hydrocarbons should be considered with caution, as these mixtures can give anomalous results (see [7] in the
Bibliography).
Flash point values are not a constant physical-chemical property of materials tested. They are a function of
the apparatus design, the condition of the apparatus used, and the operational procedure carried out. Flash
point can therefore only be defined in terms of a standard test method, and no general valid correlation can be
guaranteed between results obtained by different test methods or with test apparatus different from that
specified.

1 Scope
This International Standard specifies a method for the determination of the ability of paints (including water-
borne paints), varnishes, paint binders, adhesives, solvents and petroleum and related products, when
maintained at a selected test temperature within the range of − 30 °C to 300 °C, and under the conditions of
test, to yield sufficient flammable vapour at this temperature to cause ignition on the application of a test flame
in a standard manner. When used in conjunction with the flash detector (A.1.6), this International Standard is
also suitable to carry out a flash/no flash test on fatty acid methyl esters (FAME).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
flash/no flash test
application of a test flame at the specified temperature of the test portion (as measured in the prescribed
manner), adjusted to a barometric pressure of 101,3 kPa, to determine whether the vapours of the test portion
ignite momentarily and a flame propagates across the surface of the liquid under the specified conditions of
test
ISO 3680:2004(E)
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, a test flame is applied and the presence or absence of a flash observed.
5 Reagents and materials
5.1 Cleaning solvent
An appropriate solvent for the removal of traces of the previous test portion 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 effective for the removal of gum-type deposits.
5.2 Verification liquids
A series of certified reference materials (CRM) and/or secondary working standards (SWS) as described in
Annex C.
6 Apparatus
6.1 General
The apparatus is described in Annex A, and this includes the details of the test cup and cover assembly,
together with dimensions and special requirements. These are shown in Figure A.1 to Figure A.5. Tests for
flash/no flash over the whole range of − 30 °C to 300 °C may require more than one instrument.
6.2 Syringes
6.2.1 2 ml syringe, adjusted to deliver 2,00 ml ± 0,05 ml and equipped, if required, with a needle suitable
for use with the apparatus at test temperatures up to and including 100 °C. When testing FAME, a 2 ml test
portion is used at all temperatures.
6.2.2 5 ml syringe, adjusted to deliver 4,00 ml ± 0,10 ml and equipped, if required, with a needle suitable
for use with the apparatus at test temperatures above 100 °C. A 5 ml syringe is not required when testing
FAME.
6.3 Barometer, accurate to 0,1 kPa. Barometers precorrected to give sea-level readings, such as those
used at weather stations and airports, shall not be used.
6.4 Heating bath or oven (optional), for warming the samples, if required, and capable of controlling the
temperature to ± 5 °C. If an oven is used, it shall be intrinsically safe for hydrocarbon vapours.
