Bob - The limits are similar, but not identical, (yet).
As to the failure mode considerations, IEC 825-1 contains requirements for imposing fault conditions on components and the like that might affect the laser class. This is probably the origin of the safety notice. Please note that fault condition testing is not currently a part of the USFDA requirements. Regards, Peter L.
