Question:
We have noticed that certification bodies are treating products incorporating laser
components in different ways. We at SEMKO have always measured the laser emission from
the product when the laser component are installed and are in operation as in normal use of
. ]4 `2 ~2 R) \% M6 w( M) Ithe product. The laser emission is also measured when abnormal operation of the product is

We are doing the measurements regardless whether the laser component, for instance a laser
reader head, is separately "laser tested" or not.
# K5 N& _1 |9 NDecision:
The complete equipment shall comply with the IEC 60825 series of standards referenced as
