Paints and varnishes - Determination of volatile organic compound (VOC) content - Part 2: Gas-chromatographic method (ISO 11890-2:2000)
The standard specifies a method for the determination of the volatile organic compound (VOC) content of paints, varnishes and their raw amterials. This part shall be used where the expected VOC content is greater than 0,1 % (by mass) and less than 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.
Beschichtungsstoffe - Bestimmung des Gehaltes an flüchtigen organischen Verbindungen (VOC-Gehalt) - Teil 2: Gaschromatographisches Verfahren (ISO 11890-2:2000)
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 ist anzuwenden, wenn der erwartete VOC-Gehalt über
0,1 % (Massenanteil) und unter 15 % (Massenanteil) liegt. Wenn der VOC-Gehalt über 15 % (Massenanteil) liegt,
darf 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 sollen.

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 Commis-
sion (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 part of ISO 11890 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11890-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes,
Subcommittee SC 10, Test methods for binders for paints and varnishes.
ISO 11890 consists of the following parts, under the general title Paints and varnishes — Determination of volatile or-
ganic compound (VOC) content:
— Part 1: Difference method
— Part 2: Gas-chromatographic method
Annex A forms a normative part of this part of ISO 11890. Annex B of this part of ISO 11890 is for information only.

Paints and varnishes — Determination of volatile organic

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 shall be used where 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
may be present and may need to be quantified by another suitable method and allowed for in the calculations.

lated Coatings.
3 Terms and definitions
For the purposes of this part of ISO 11890, the following terms and definitions apply.
3.1
VOC
volatile organic compound
fundamentally, any organic liquid and/or solid that evaporates spontaneously at the prevailing temperature and pres-
sure of the atmosphere with which it is in contact
[ISO 4618-1:1998]
3.2
VOC content
volatile organic compound content
the mass of the volatile organic compounds present in a coating material, as determined under specified conditions
NOTE 1 The properties and the amount 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 agreement.
NOTE 2 Under certain US governmental legislation, the term VOC is restricted solely to those compounds that are photochemi-
cally active in the atmosphere (see ASTM D 3960). Any other compound is then defined as being an exempt compound.
[Adapted from ISO 4618-1:1998]
3.3
exempt compound
organic compound that does not participate in atmospheric photochemical reactions (see note 2 to definition 3.2)
3.4
ready for use
the 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
4Principle
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 com-
pounds 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 per-
formed 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 supple-
mentary information. The items of supplementary information are given in annex A.

6Apparatus
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 sam-
ple 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 moni-
tored. 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 pro-
vided with silanized glass wool packing and shall be maintained as specified in 6.2.2. The split ratio shall be adjusta-
ble 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.
