I'm sure we have been through this all before, but here goes : For equipment certified by UL and CSA (and I assume by other agencies, but I have no personal experience), the End of Line Tests will be specified as part of your certification.
For Europe, there is EN 50116, which "defines the routine electrical safety tests and their procedures to be applied during or after the manufacturing process of equipment certified or declared as complying with EN 60950." This requires the Earth Bonding Test at 1.5 times the current capacity of the circuit, but not more than 25A, with the 0.1 ohm limit, and an electric stregth test of 1500V ac or the dc equivalent, for basic insulation, and 3000V or the dc equivalent for reinforced insulation, with the proviso that "testing of components connected between the primary and secondary circuits shall be performed before final assembly". (i.e. it is ok to use power supplies where the transformers, etc, have been 100% tested at 3000V). There is no Insulation Resistance Test specified, and I am unaware of any such requirement for IT products.
