Ein Vorwort
ISO (Internationale Standardisierungsorganisation) ist eine globale Allianz nationaler Normungsgremien (ISO-Mitgliedsorganisationen). Die Entwicklung internationaler Standards erfolgt in der Regel durch technische Komitees der ISO. Jede Mitgliedsinstitution, die sich für ein Thema interessiert, zu dem ein Fachausschuss eingerichtet wurde, hat das Recht, im Ausschuss vertreten zu sein. An dieser Arbeit sind auch staatliche und nichtstaatliche internationale Organisationen beteiligt, die mit Standardisierungsorganisationen zusammenarbeiten. ISO arbeitet eng mit der International Electrotechnical Commission zusammen (IEC) in allen Fragen der elektrischen Normung.

Einführung
This document is one of a series of standards dealing with the sampling and testing of coating materials and their raw materials. It provides a method for the determination of volatile organic compound (VOC) content and semi-volatile organic compound (SVOC) content of coating materials and their raw materials.

Warnings Use of this document may involve hazardous materials, Operationen, und Ausrüstung. Dieses Dokument soll nicht alle mit seiner Verwendung verbundenen Sicherheitsbedenken ansprechen. It is the responsibility of the user of this document to take appropriate steps to ensure the safety and health of personnel before applying the document and to determine whether any other restrictions are applicable for this purpose.

ISO 11890-2-2020 “Farben und Lacke – Bestimmung flüchtiger organischer Verbindungen (VOC) Inhalt – Teil 2- Gaschromatographie”

1 Umfang
This document is suitable for the determination of VOC and/or SVOC with an expected VOC and SVOC content greater than 0.01 % (Masse) Zu 100 %.

The method given in ISO 11890-1 is used when the VOC mass is greater than 15%. This document (method ISO 11890-2) is applicable when the system contains both VOC and SVOC, as the VOC results of ISO 11890-1 May be affected by SVOC. For VOC content of less than 0.1%, the headspace method described in ISO 17895 was used as an alternative. ISO 11890-1 und ISO 17895 cannot be used to determine SVOC content.

Notiz 1 Certain components of coating materials and their raw materials can decompose and cause artificial VOC and/or SVOC signals during analysis. These signals are artifacts of the method and are not taken into account when determining the VOC and/or SVOC of coating materials and their raw materials (examples are given in Annex B).

This method assumes that the volatile matter is water or organic matter. Jedoch, other volatile inorganic compounds may be present and may need to be quantified by another suitable method and allowed in the calculations. The methods defined in this document are not applicable to the determination of moisture content.

Notiz 2 If organic acids or bases and their corresponding salts are present in the coating material or its raw materials, the amount quantified by this method may not be accurate due to changes in the acid or base balance.

3.1 Volatile Organic Compounds
Volatile organic compounds

Any organic liquid and/or solid that evaporates spontaneously at the prevailing temperature and pressure of the atmosphere with which it is in contact

Notiz 1: For current usage of the term VOC in the field of coatings, see Volatile Organic Compound content (VOC content) (3.4).

Notiz 2: Under U.S. government legislation, the term VOC is limited to those compounds that are photochemically active in the atmosphere (see ASTM D3960). Any other compound is then defined as an exempt compound (3.6).

[Quelle: ISO 4618:2014, 2.270]

3.2 Semi-volatile organic compounds
SVOC

Organic liquids and/or solids, spontaneously evaporate at the prevailing temperature and pressure of the atmosphere in contact with them, but more slowly than vocs

Notiz 1: For current usage of the term SVOC in the field of coating materials, see semi-volatile Organic Compound Content (SVOC content) (3.5).

Volatile organic compounds

The quality of volatile organic compounds (3.1) present in the coating material as determined under the specified conditions
