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 third edition cancels and replaces the second edition (ISO 11890-2:2006), of which it constitutes a
minor revision to correct the numerator of the fraction in Equation (6) in 10.5.
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
INTERNATIONAL STANDARD ISO 11890-2:2013(E)
Paints and varnishes — Determination of volatile organic
compound (VOC) content —
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 to entry: As to current usage of the term VOC in the field of coating materials, see volatile organic compound
content (VOC content).
ISO 11890-2:2013(E)
Note 2 to entry: Under US government legislation, the term VOC is restricted solely to those compounds that are
photochemically active in the atmosphere (see ASTM D3960). Any other compound is then defined as being an
exempt compound.
Note 3 to entry: 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.
[SOURCE: ISO 4618:2006, modified — Note 3 to entry has been added.]
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 to entry: 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.
Note 2 to entry: 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.
[SOURCE: ISO 4618:2006, modified — Note 2 to entry has been added.]
3.3
exempt compound
organic compound that does not participate in atmospheric photochemical reactions
Note 1 to entry: See Note 2 to entry and Note 3 to entry in 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 might 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.

ISO 11890-2:2013(E)
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
