Paints and varnishes - Determination of volatile organic compounds(VOC) and/or semi volatile organic compounds (SVOC) content - Part 2: Gas-chromatographic method (ISO 11890-2:2020)

This document is applicable for the determination of VOC and SVOC with an expected VOC and/or SVOC content greater than 0,01 % by mass up to 100 % by mass.
The method given in ISO 11890-1 is used when the VOC is greater than 15 % by mass. This document (method ISO 11890-2) applies when the system contains VOC and SVOC as the VOC result of ISO 11890-1 can be influenced by the SVOC. For VOC content smaller than 0,1 %, the head space method described in ISO 17895 is used as an alternative. ISO 11890-1 and ISO 17895 cannot be used for the determination of the SVOC content.
NOTE 1 Some ingredients of coating materials and their raw materials can decompose during analysis and cause artificial VOC and/or SVOC signals. When determining VOC and/or SVOC for coating materials and their raw materials, these signals are artefacts of the method and are not taken into account (examples are given in Annex B).
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. The method defined in this document is not applicable for determination of water content.
NOTE 2 If organic acids or bases and their corresponding salts are present in the coating material or its raw materials, the amount that is quantified by this method might not be accurate due to a change in the acid or base equilibrium.

Beschichtungsstoffe - Bestimmung des Gehaltes an flüchtigen organischen Verbindungen (VOC-Gehalt) und des Gehaltes an halbflüchtigen organischen Verbindungen (SVOC-Gehalt) - Teil 2: Gaschromatographisches Verfahren (ISO 11890-2:2020)

Dieses Dokument gilt für die Bestimmung von VOC und/oder SVOC bei einem erwarteten Gehalt über 0,01 % (Massenanteil) bis zu 100 % (Massenanteil).
Das in ISO 11890 1 angegebene Verfahren wird verwendet, wenn der VOC Gehalt über 15 % (Massenanteil) liegt. Dieses Dokument (Verfahren nach ISO 11890 2) gilt, wenn das System VOC und SVOC enthält, da das VOC Ergebnis nach ISO 11890 1 durch SVOC beeinflusst werden kann. Für einen VOC Gehalt unter 0,1 % wird das in ISO 17895 beschriebene Kopfraumverfahren als Alternative verwendet. ISO 11890 1 und ISO 17895 können nicht für die Bestimmung des SVOC Gehaltes verwendet werden.
ANMERKUNG 1: Einige Bestandteile von Beschichtungsstoffen und ihren Rohstoffen können während der Analyse zerfallen und künstliche VOC  und/oder SVOC Signale verursachen. Bei der Bestimmung von VOC und/oder SVOC für Beschichtungsstoffe und ihre Rohstoffe sind diese Signale Artefakte des Verfahrens und werden nicht berücksichtigt (Beispiele werden in Anhang B gegeben).
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 vorhanden sein, die durch ein anderes geeignetes Verfahren bestimmt und in den Berechnungen berücksichtigt werden dürfen. Das in diesem Dokument beschriebene Verfahren gilt nicht für die Bestimmung des Wassergehaltes.
ANMERKUNG 2: Wenn in dem Beschichtungsstoff oder seinen Rohstoffen organische Säuren oder Basen und ihre entsprechenden Salze vorhanden sind, ist die mit diesem Verfahren bestimmte Menge aufgrund einer Änderung des Säure-Base-Gleichgewichts möglicherweise nicht genau.

Peintures et vernis - Détermination de la teneur en composés organiques volatils (COV) et/ou composés organiques semi-volatils (COSV) - Partie 2: Méthode par chromatographie en phase gazeuse (ISO 11890-2:2020)

Le présent document est applicable à la détermination des COV et des COSV pour lesquels la teneur attendue en COV et/ou en COSV est supérieure à 0,01 % en masse et jusqu'à 100 % en masse.
La méthode donnée dans l'ISO 11890-1 est utilisée lorsque la teneur en COV est supérieure à 15 % en masse. Le présent document (méthode ISO 11890-2) s'applique lorsque le système contient des COV et des COSV, car le résultat obtenu selon l'ISO 11890-1 peut être influencé par les COSV. Pour une teneur en COV inférieure à 0,1 %, la méthode de l'espace de tête décrite dans l'ISO 17895 est utilisée en guise d'alternative. L'ISO 11890-1 et l'ISO 17895 ne peuvent pas être utilisées pour la détermination de la teneur en COSV.
NOTE 1 Certains ingrédients des produits de peinture et de leurs matières premières peuvent se décomposer pendant l'analyse et causer des signaux COV et/ou COSV artificiels. Lors de la détermination des COV et/ou des COSV dans les produits de peinture et leurs matières premières, ces signaux sont des artefacts de la méthode et ne sont pas pris en compte (des exemples sont donnés à l'Annexe B).
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 adaptée et d'en tenir compte dans les calculs. La méthode définie dans le présent document n'est pas applicable à la détermination de la teneur en eau.
NOTE 2 Si des acides ou des bases organiques et leurs sels correspondants sont présents dans le produit de peinture ou ses matières premières, la quantité qui est quantifiée par cette méthode pourrait ne pas être exacte en raison d'une modification de l'équilibre acido-basique.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

WARNING — The use of this document can involve hazardous materials, operations and

equipment. This document does not purport to address all of the safety problems associated

with its use. It is the responsibility of users of this document to take appropriate measures

to ensure the safety and health of personnel prior to the application of the document, and to

determine the applicability of any other restrictions for this purpose.
1 Scope

This document is applicable for the determination of VOC and SVOC with an expected VOC and/or SVOC

content greater than 0,01 % by mass up to 100 % by mass.

The method given in ISO 11890-1 is used when the VOC is greater than 15 % by mass. This document

(method ISO 11890-2) applies when the system contains VOC and SVOC as the VOC result of ISO 11890-1

can be influenced by the SVOC. For VOC content smaller than 0,1 %, the head space method described in

ISO 17895 is used as an alternative. ISO 11890-1 and ISO 17895 cannot be used for the determination of

the SVOC content.

NOTE 1 Some ingredients of coating materials and their raw materials can decompose during analysis and

cause artificial VOC and/or SVOC signals. When determining VOC and/or SVOC for coating materials and their

raw materials, these signals are artefacts of the method and are not taken into account (examples are given in

Annex B).

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. The method defined in this document is not applicable for determination

of water content.

NOTE 2 If organic acids or bases and their corresponding salts are present in the coating material or its raw

materials, the amount that is quantified by this method might not be accurate due to a change in the acid or base

equilibrium.

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

compounds content (VOC content) (3.4).

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 (3.6).
[SOURCE: ISO 4618:2014, 2.270]
3.2
semi-volatile organic compound
SVOC

organic liquid and/or solid that evaporates spontaneously but slower in comparison to VOC at the

prevailing temperature and pressure of the atmosphere with which it is in contact

3.4
volatile organic compounds content
VOC content
VOCC

mass of the volatile organic compounds (3.1) 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, the compounds

considered to be part of the VOC content are those with boiling points below and including that limit, and

compounds with higher boiling points are considered to be semi-volatile or non-volatile organic compounds.

4 Principle

After preparation of the sample, the VOCs, SVOCs and NVOCs 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, e.g. via GC-MS, they are

quantified from the peak areas with respect to their compound specific relative response with the

help of an internal standard, via GC-FID. Non-identifiable substances are quantified with respect to a

surrogate standard that can be identical to the internal standard. A calculation is performed to give the

VOC and/or SVOC content of the sample.
5 Required information

For any particular application, the information required should preferably be agreed between the

interested parties and may be derived, in part or totally, from an international or national standard or

other document related to the product under test.
The required information can include the following points:
a) the organic compound(s) to be determined (see Clause 9);
b) the experimental conditions to be used (see 8.5);
c) the classification criteria for VOC and/or SVOC;
d) which of the organic compounds in a) are exempt compounds (if relevant);
e) the method of calculation to be used (see Clause 10 and Clause 11).
