This is a very controversial matter, and the more surprising requirements are being toned down. Use the product safety standard (IECEN60065, 60950, etc.) to guide you. > >When googling, I came across a reference to a standard IEC/TS 60825-6, >"Safety of products with optical sources, exclusively used for visible >information transmission to the human eye" (1999-07).

You don't need it, and an IEC TS is not likely to become and EN, but might become an ENV. >What is the approach for indicating LEDs for EU compliance (CE >marking)? Apply the relevant product safety standard. An IEC product safety WG concluded recently: " From recent measurements it is clear that, by applying A.2 to the IEC 60825, remote controls are below class 1. This was confirmed by test results of NEMKO." -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
