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?

In this case, I would do as you have done and subject the whole finished wood component to a single CDPH Standard Method v1.1–2010 test.

French VOC class A+ is sufficient only for composite wood. Wooden flooring needs the general emissions evaluation, either by CDPH testing or by AgBB testing plus low formaldehyde emissions (only the low formaldehyde emissions can be demonstated by VOC class A+, as A+ class does not include AgBB limit values.
The evaluation is required for the final product as it reaches the construction site. Factory-applied varnishes do not need separate evaluation then.
