Vibration acceptance criteria for equipment tested at lower loads

[cowpen]

I'm trying to gain some insight if there are any common practices for vibration acceptance criteria when an equipment is not tested up to it's rated load.

For context: we have a generator which is connected to a turbo expander; the power generated would be a function of the process conditions (dP, flow, density). At the moment, process conditions will only give us approx. one third of the power.

I work on the client side- but it is not clear to me what criteria may be used since we won't be operating at design conditions. (instrumentation available: proximitors, accelerometers)

There may be advice in some standards such as BS ISO 10816-2:2001?

Some industries kind of expect no load acceptance testing.
