IEC 825-1/EN 60825-1 requires all LEDs to be classified as 1, 2, or 3. The classification is determined by the end-product, not by the LED manufacturer. The problem is that a failure in the end-product may cause the LED to change from Class 1 to Class 2. The only way a LED manufacturer can classify the LED is to determine that the LED will consistently self-destruct before the emission goes to the next higher class. Furthermore, the standard REQUIRES the emission class to be marked on the product or in the instruction manual. But, does the exemption quoted above exempt the label requirement contained in Clause 3? Just what does the word "further" mean in this context? So, any product that uses a LED for any purpose whatsover may or may not need to include an identification as to LED class. Nevertheless, compliance to EN 60825-1 must be included in the Declaration of Compliance. Best regards, Rich
