If you are Class I, the only production line test required is 2.12 kVdc between primary to chassis.

For mains supplies over 150V, the routine production test voltages are 2.12kVdc for basic insulation and 3.54kVdc for double or reinforced insulation. So you'd normally expect to use 2.12kVdc for class I products, unless there are parts of the product emplying class II construction?

The products are class 1 audio products type tested to IEC 60065. We are unable to do the lower voltage ac test because of the emi filtering in the PSU. Can anyone tell me how this voltage level was arrived at and why it has been increasing over the past decade? I am a little concerned that it may be over stressing some components and may lead to increased field failures. Thanks in advance Ian McBurney.
