Paints and varnishes - Determination of volatile organic compound (VOC) content - Part 2: Gas-chromatographic method (ISO 11890-2:2006)
This part of ISO 11890 is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. It specifies a method for the determination of the volatile organic compound (VOC) content of paints, varnishes and their raw materials. This part is preferred if the expected VOC content is greater than 0,1 % by mass and less than about 15 % by mass. When the VOC content is greater than about 15 % by mass, the less complicated method given in ISO 11890-1 may be used. This method assumes that the volatile matter is either water or organic. However, other volatile inorganic compounds can be present and might need to be quantified by another suitable method and allowed for in the calculations.
Beschichtungsstoffe - Bestimmung des Gehaltes an flüchtigen organischen Verbindungen (VOC-Gehalt) - Teil 2: Gaschromatographisches Verfahren (ISO 11890-2:2006)
Dieser Teil von ISO 11890 gehört zu einer Reihe von Normen, welche die Probenahme und Prüfung von Beschichtungsstoffen und ähnlichen Produkten behandelt.
Er legt ein Verfahren zum Bestimmen des Gehaltes an flüchtigen organischen Verbindungen (VOC Gehalt) in Beschichtungsstoffen und deren Rohstoffen fest. Dieser Teil darf angewendet werden, wenn der erwartete VOC-Gehalt über 0,1 % (Massenanteil) und unter 15 % (Massenanteil) liegt. Wenn der VOC-Gehalt über 15 % (Massenanteil) liegt, sollte das weniger komplizierte Verfahren nach ISO 11890-1 angewendet werden.
Dieses Verfahren geht davon aus, dass es sich bei den flüchtigen Anteilen entweder um Wasser oder um organische Verbindungen handelt. Es können jedoch andere flüchtige anorganische Verbindungen anwesend sein, die durch ein anderes geeignetes Verfahren bestimmt und in den Berechnungen berücksichtigt werden dürfen.
Peintures et vernis - Détermination de la teneur en composés organiques volatils (COV) - Partie 2: Méthode par chromatographie en phase gazeuse (ISO 11890-2:2006)
L'ISO 11890-2:2006 fait partie d'une série de normes qui traitent de l'échantillonnage et des essais relatifs aux peintures, vernis et produits assimilés.
Elle spécifie une méthode de détermination de la teneur en composés organiques volatils (COV) des peintures, vernis et de leurs matières premières. Cette méthode est à utiliser de préférence si la teneur escomptée en COV est comprise entre 0,1 % en masse et environ 15 % en masse. Si la teneur en COV est supérieure à environ 15 % en masse, la méthode plus simple préconisée dans l'ISO 11890-1 peut être utilisée.
Cette méthode suppose que la matière volatile est de l'eau ou une matière organique. Toutefois, d'autres composés inorganiques volatils peuvent être présents; il pourrait être nécessaire de les quantifier selon une autre méthode et d'en tenir compte dans les calculs.

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 11890-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes.
This second edition cancels and replaces the first edition (ISO 11890-2:2000), which has been technically
revised. The main changes are:
⎯ the method has been modified to allow the determination of the VOC content when the term refers to
compounds with a well-defined boiling point;
⎯ the calculation of the VOC content of a product “ready for use” less water and less exempt compounds
(see 10.5) has been modified to make it clear that only those components that are not exempt
compounds are considered.
ISO 11890 consists of the following parts, under the general title Paints and varnishes — Determination of
volatile organic compound (VOC) content:
⎯ Part 1: Difference method
⎯ Part 2: Gas-chromatographic method

Part 2:
Gas-chromatographic method
1 Scope
This part of ISO 11890 is one of a series of standards dealing with the sampling and testing of paints,
varnishes and related products.
It specifies a method for the determination of the volatile organic compound (VOC) content of paints,
varnishes and their raw materials. This part is preferred if the expected VOC content is greater than 0,1 % by
mass and less than about 15 % by mass. When the VOC content is greater than about 15 % by mass, the
less complicated method given in ISO 11890-1 may be used.
This method assumes that the volatile matter is either water or organic. However, other volatile inorganic
compounds can be present and might need to be quantified by another suitable method and allowed for in the
calculations.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
volatile organic compound
VOC
any organic liquid and/or solid that evaporates spontaneously at the prevailing temperature and pressure of
the atmosphere with which it is in contact
NOTE 1 As to current usage of the term VOC in the field of coating materials, see volatile organic compound content
(VOC content).
NOTE 2 Under U.S. government legislation, the term VOC is restricted solely to those compounds that are
photochemically active in the atmosphere (see ASTM D 3960). Any other compound is then defined as being an exempt
compound.
[ISO 4618:2006]
NOTE 3 Under European legislation, EU Directive 2004/42/EC, the term VOC refers to volatile organic compounds with
boiling points up to 250 °C, measured at a standard pressure of 101,3 kPa.
3.2
volatile organic compound content
VOC content
mass of the volatile organic compounds present in a coating material, as determined under specified
conditions
NOTE 1 The properties and the amounts of the compounds to be taken into account will depend on the field of
application of the coating material. For each field of application, the limiting values and the methods of determination or
calculation are stipulated by regulations or by agreement.
[ISO 4618:2006]
NOTE 2 If the term VOC refers to compounds with a defined maximum boiling point (see Note 3 to 3.1), the
compounds considered to be part of the VOC content are those with boiling points below that limit and compounds with
higher boiling points are considered to be non-volatile organic compounds.
3.3
exempt compound
organic compound that does not participate in atmospheric photochemical reactions
NOTE See Notes 2 and 3 to 3.1.
3.4
ready for use
state of a product when it is mixed in accordance with the manufacturer's instructions in the correct
proportions and thinned if required using the correct thinners so that it is ready for application by the approved
method
4 Principle
After preparation of the sample, the VOCs are separated by a gas-chromatographic technique. Either a hot or
a cold sample injection system is used, depending on the sample type. Hot injection is the preferred method.
After the compounds have been identified, they are quantified from the peak areas using an internal standard.
Depending on the equipment used, it may also be possible to determine the water content by this method. A
calculation is then performed to give the VOC content of the sample.

5 Required supplementary information
For any particular application, the test method specified in this part of ISO 11890 needs to be completed by
supplementary information. The items of supplementary information are given in Annex A.
6 Apparatus
6.1 Gas chromatograph
The apparatus shall be set up and used in accordance with the manufacturer's instructions. All of the
instrumental parts coming into contact with the test sample shall be made of a material (e.g. glass) which is
resistant to the sample and will not change it chemically.
6.2 Sample injection system
6.2.1 General
Use one of the two types specified in 6.2.2 and 6.2.3.
6.2.2 Hot-injection system with sample splitter (preferred system)
The instrument shall have a variable-temperature injection block with a sample splitter. The injection
temperature shall be capable of being set to an accuracy of 1 °C. The split ratio shall be adjustable and
capable of being monitored. The sample splitter insert shall contain silanized glass wool to retain non-volatile
constituents, and shall be cleaned and provided with new glass wool packing or replaced as required to rule
out errors due to residues of binder or pigment (i.e. adsorption of compounds). The occurrence of adsorption
is revealed by peak tailing, in particular with components of low volatility.
6.2.3 Cold-injection system with sample splitter
The cold-injection system shall be provided with temperature programming for heating from ambient to 300 °C
and shall have a sample splitter inlet which is made of an inert material such as glass. The sample splitter
shall be provided with silanized glass wool packing and shall be maintained as specified in 6.2.2. The split
ratio shall be adjustable and capable of being monitored.
Method precision will be increased if the injection system, especially the hot-injection system, is coupled to an
auto-injector. The manufacturer's instructions shall be followed when an auto-injector is used.
6.2.4 Selection of sample injection system
The choice between hot-injection and cold-injection will depend on the type of product under test. It will be
necessary to use the cold-injection system for products which at high temperature release substances which
interfere with the determination.
Indications of cleavage or decomposition reactions may be obtained by looking for changes in the
chromatogram (for example the occurrence of foreign peaks or an increase or decrease in peak size) at
various sample injector temperatures.
The hot-injection system covers all of the volatile constituents, compounds and cleavage products of the
binders and additives. Cleavage products of the binders or additives which are identical to a constituent of the
product can be separated by a cold-injection system, since they elute later as a result of the programmed
increase in injection block temperature.

ISO 11890-2:2006(E)
6.3 Oven
The oven shall be capable of being heated between 40 °C and 300 °C both isothermally and under
programmed temperature control. It shall be possible to set the oven temperature to within 1 °C. The final
temperature of the temperature programme shall not exceed the maximum operating temperature of the
column (see 6.5).
6.4 Detector
Any of the following three detectors may be used, as well as other detectors suitable for specific types of
compound:
6.4.1 Flame ionization detector (FID), capable of being operated at temperatures up to 300 °C. To
prevent condensation, the detector temperature shall be at least 10 °C above the maximum oven temperature.
The detector gas supply, injection volume, split ratio and gain setting shall be optimized so that the signals
(peak areas) used for the calculation are proportional to the amount of substance.
6.4.2 Suitably calibrated and tuned mass spectrometer or other mass-selective detector.
6.4.3 Suitably calibrated Fourier-transform infrared spectrometer (FT-IR spectrometer).
6.5 Capillary column
The column shall be made of glass or fused silica. Columns of sufficient length to resolve volatiles and of
maximum internal diameter 0,32 mm, coated with unmodified or phenyl-modified poly(dimethylsiloxane) or
poly(ethylene glycol) at a suitable film thickness, have been shown to give good peak separation. The
stationary phase and column length shall be chosen to suit the particular separation (see examples in
Annex B).
A suitable combination of column, temperature programme and marker compound shall be chosen such that
compounds in the sample which are defined as VOCs by virtue of their boiling point (see Note 3 to 3.1) elute
before the boiling-poin
