ISO 11890-1:2024

This document is part of the ISO 11890 series, dealing with the sampling and testing of coating materials and their raw materials.

This document is applicable to the determination of volatile organic compound (VOC) content in the following cases:

case 3: where there are radiation curable coating materials, and the expected VOC content is greater than a mass fraction of 5%. Radiation curable coating materials in this document include coating materials that are cured by UV, electron beam, and other radiation methods.

If the system of the first case contains SVOC, but do not cure through chemical reactions, the VOC result can be influenced by SVOC, see AnnexC. In this case, ISO 11890-2 is preferred. ISO 11890-1 cannot be used for the determination of the SVOC content. In water-borne coating materials, that do not cure through chemical reactions, if the water content is much greater than VOC content and VOC content is less than a mass fraction of 10%, ISO 11890-2 is preferred.

For all three cases, the main purpose measured is VOC. However, clarify that this VOC content can also contain SVOC. The real VOC content can be lower than the VOC content measured by ISO11890-1.

The method specified in this document assumes that the volatile matter is either water or organic. However, it is possible that other volatile inorganic compounds are present which can require another suitable method for quantification, which is thus allowed for in the calculations. The method defined in this document is not applicable for determination of water content.
