Yes.
At least one certification house demands measurement
data for each indicator LED. Emission class must be
identified on the product or in the manual. (Note
that emission class is determined under single-fault
conditions in the driving circuit.)
However, in practice, other certification houses use
a get-out for indicator LEDs. Usually this is in the
form of a "not tested, but may be required by some
authorities" statement in the report.
Most indicator LED manufacturers do not know of EN
60825-1, and have no idea how to test.
Measurement is not easy, especially the determination
of the aperture.
Most indicator LEDs will open before achieving Class
2 emission levels.
The above does not apply to automotive LEDs or to
traffic signal LEDs.
Best regards,
Rich
