Its scope of application would be only applied to LASER products after September 2010, and LED lighting products are no longer covered by the latest version of IEC / EN 60825-1, but need to be assessed in accordance with IEC / EN 62471 . IEC / EN62471 is a test standard for laser products (including LED) issued by the European Union.

Electronic products, no matter components, parts or machines, all need aging test. Aging and test is not one concept, aging firstly and then test. Electronic product after manufacturing forms a complete product, which is able to play its role.
