Popis
BS ISO 21360-2:2020
This standard BS ISO 21360-2:2020 Vacuum technology. Standard methods for measuring vacuum-pump performance is classified in these ICS categories:
- 23.160 Vacuum technology
This document 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.
In this document, it is necessary to use the determinations of volume flow rate and base pressure specified in ISO 21360-1.
This document also applies to the testing of other types of pumps which can discharge gas against atmospheric pressure, e.g. drag pumps.
