You need to go to the ***product standards***. EN 55022 for general EMC emissions EN 55024 for EMC immunity EN 61000-3-2 for low-frequency conducted emissions EN 61000-3-3 for voltage changes imposed on the mains supply The first two standards explain which Basic Standards in the 61000-4- series shall be applied to ITE, and include a vast amount of additional information on exactly how the tests shall be performed. The third and fourth refer to EN 61000-4-7 and EN 61000-4-15 respectively. EN 60950-1 is the Product Standard for safety > > I have not got a satisfactory answer from the test labs I have > used. That's VERY disturbing. They seem to be misleading you, which is very reprehensible. -- Regards, John Woodgate, OOO - Own Opinions Only. The good news is that nothing is compulsory.
