Chaque institution membre intéressée par un sujet pour lequel un comité technique a été créé a le droit d'être représentée au sein du comité.. Les organisations internationales gouvernementales et non gouvernementales qui assurent la liaison avec les organismes de normalisation sont également impliquées dans ces travaux.. L'ISO travaille en étroite collaboration avec la Commission électrotechnique internationale (CEI) sur toutes les questions de normalisation électrique.

Compared with the previous edition, the main changes are as follows:

– The scope has been expanded to include the determination of semi-volatile organic compounds (SVOC);

— The range has been expanded to include concentrations ranging from 0.01% à 100%;

– Added specification for the determination of semi-volatile organic compounds.

Introduction
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 (COV) content and semi-volatile organic compound (SVOC) content of coating materials and their raw materials.

Avertissements L'utilisation de ce document peut impliquer des matières dangereuses, opérations, et l'équipement. Ce document n'est pas destiné à répondre à tous les problèmes de sécurité associés à son utilisation.. 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.

OIN 11890-2-2020 “Peintures et vernis – Détermination des composés organiques volatils (COV) contenu – Partie 2- Chromatographie des gaz”

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

The method given in ISO 11890-1 is used when the VOC mass is greater than 15%. Ce 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. OIN 11890-1 et ISO 17895 cannot be used to determine SVOC content.

Note 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. Cependant, 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.

Note 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

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

Note 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).

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

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

3.4 Volatile organic compound content
Volatile organic compound content

Volatile organic compounds

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

Note 1: The nature and number of compounds to be considered will depend on the application area of the coating material. For each application area, limit values as well as determination or calculation methods are specified by regulation or agreement.

Note 2: If the term VOC refers to a compound with a specified maximum boiling point, compounds considered as part of the VOC content are those whose boiling point is below and includes this limit, while compounds with higher boiling points are considered as semi-volatile or non-volatile organic compounds.

3.12 Extraction solvent
Liquid used to extract volatile organic compounds and Svocs from the substrates under study

3.13 Main peak
A peak that makes a significant contribution to either side
