Vacuum technology - Standard methods for measuring vacuum-pump performance - Part 2 : positive displacement vacuum pumps

This part of ISO 21360 specifies methods for measuring the volume flow rate, base pressure, water vapourtolerance, 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 part of ISO 21360, it is necessary to use the determinations of volume flow rate and base pressurespecified in ISO 21360‑1.This part of ISO 21360 also applies to the testing of other types of pumps which can discharge gas againstatmospheric pressure, e.g. drag pumps.

Vacuum technology - Standard methods for measuring vacuum-pump performance - Part 2 : positive displacement vacuum pumps

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.

In this part of ISO 21360, it is necessary to use the determinations of volume flow rate and base pressure

specified in ISO 21360‑1.

This part of ISO 21360 also applies to the testing of other types of pumps which can discharge gas against

atmospheric pressure, e.g. drag pumps.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
