We have been looking at the standard in Japan and found it technically difficult to do as a laboratory, because you need to be able to measure the light's spectral response outside of the treatment region, with incredibly small limits applied (some limits end up being in the nW/cm2 region, if I remember correctly).
In general, even if a lab is "qualified" under the CB for a particular standard, they usually lean on the manufacturer to provide them test data for such kind of unusual tests. So even even if you find a lab, double check if they can really do the tests or if they rely on manufacturer data.
