This part of ISO 21360 specifies methods for measuring the volume flow rate, base pressure, water vapour

tolerance, power consumption, and the lowest start-up temperature of positive displacement vacuum pumps,

which discharge gas against atmospheric pressure and with a usual base pressure <10 kPa.
