Abstract

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 1: where there are single-pack coating materials other than case 3, and the expected VOC content is greater than a mass fraction of 5 %, including single-pack coating materials cure not through chemical reactions and single-pack coating materials which cannot be measured by ISO 11890-2 due to chemical cure reactions or gas chromatography temperatures leading to formation of new compounds that would not appear under normal cure conditions and impacts VOC/SVOC calculation.;
  • case 2: where there are multi-pack coating materials other than case 3 and the expected VOC content is greater than a mass fraction of 1 %;
    • 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 Annex C. In this case, ISO 11890-2 shall be 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 shall be preferred. In the third case, the main purpose measured is VOC. However, it needs to be clarified that this VOC content can also contain SVOC. The real VOC content may be lower than the VOC content measured by ISO 11890-1. 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
