The answer from EN50091-1-1 is... Worst case voltage within the range specified by the manufacturer. If a range is not specified, it's +6%, -10%. Note that this over-rules the '950 bit about increasing that range to +10% for 230Vac single-phase or 400Vac 3-phase. This version of the UPS standard uses the old EN60950 +A1 +A2 as a reference.
>From EN62040-1-1, the answer is slightly different. This version of the UPS standard uses the new EN60950-1 as a reference, and accepts its requirements of 1.4.1, 1.4.2, 1.4.3, 1.4.6, 1.4.7, 1.4.8, 1.4.10, 1.4.11, 1.4.12, 1.4.13, and 1.4.14 as is (but not the missing subclauses) and then adds a note saying only the heating and leakage tests are done with voltage tolerances, all the rest being done at nominal voltage.

What is the voltage range (percentage of rated voltage) defined for heating and other tests in the above standard for normal and abnormal operation? Any help in this regard appreciated. Nick.
