A finished wood floor has been varnished off-site previous to installation in a office project. The varnish is unknown, so both the wood and varnish have been tested together for VOC emissions using the ISO 16000 standards. The results show that it is compliant to French VOC Labeling and is labelled Class A+. Under which category does this material has to be evaluated? do complementary emissions tests have to be done? should the wood and the varnish be tested separately?
