Richard, I don't believe that the standard applies to LED indicators instead it is for 'LED-based optics' used in fiber optic transmission.

Some of our ITE products have LED indicators. A well know European based agency has evaluated them based upon the manufacturer's specifications and our circuit designs. Yes, fault conditions must be considered but usually there is sufficient information in the data sheets to indicate that the device is compliant at the higher voltage. In a couple of cases, we have had some difficulty due to the lack of sufficient information on the data sheet; and we had to obtain more information from the manufacturer. We have never had to perform emission testing, and we have not been instructed to include the laser marking even though we display the agency's compliance mark.

Hi group, When evaluating IEC 825-1 for fiber optic LAN transceivers I came across requirements for LED's. I have known that the EU had some requirements for LED emission. Being on the US side of the pond I have not seen how it is applied. Are manufactures doing fault testing on LED to ensure the class 1 levels are maintained? Are manufacturers labeling products with LED's (this covers just about every electronic product I know of) with the "CLASS 1 LED PRODUCT" as required in 5.12 of IEC 825?
