As reported earlier, the EU ecolabel for paints and varnishes contained requirements on SVOC content testing that confused the testing labs because it required use of ISO 11890-2 for that purpose. But that standard was not made for that purpose, for SVOC testing, omly for VOC testing.
The ISO 11890-2 standard can be expanded to include SVOC testing as well, but this is not yet specified in a harmonized manner. Each concerned testing lab tried to solve that challenge in its own manner, but differently from each other. This resulted in significantly different test results obtained from different testing labs.
Industry initiatives tried to remediate that unsatisfactory solution by publishing an interpretative guidance on how the scope of ISO 11890-2 could be expanded, to allow determination of SVOCs within the same analytical procedure as ISO 11890-2 – see our recent post in this blog.
A 2015 revision of the EU ecolabel criteria document allowed to make such changes in a way that ensures more uniform test results on a specific paint formulation than the first published version of the EU ecolabel criteria did. Earlier, two different analytical procedures had been specified – now only one of these remains. The so-called “polar system” was cancelled in the criteria document.
The updated User Manual (version 1.2) of the EU ecolabel for paints and varnishes contains a more stringent guidance on SVOC testing. ISO/TC 35 WG1 started work on an amendment or revision of ISO 11890-2. Several analytical challenges still need to be solved. This work will continue in 2017. A publication of the draft revised ISO 11890-2 standard may occur late 2017 or 2018.
Until then, the testing labs should follow the above mentioned guidance. The VOC testing lab of Eurofins Product Testing A/S in Denmark is ISO 17025 accredited for ISO 11890-2 testing. The most recent progress of standardization work at ISO will be taken on board continuously. This ensures that test results of Eurofins sill be valid also in the future.
