Positive-displacement vacuum pumps — Measurement of performance characteristics — Part 2: Measurement of ultimate pressure

Pompes primaires volumétriques à vide — Mesurage des caractéristiques fonctionnelles — Partie 2: Mesurage de la pression limite

Abstract / scope

The considered pumps discharge the gas against atmosphere pressure and achieve a limiting inlet pressure of less than 100 Pa in one stage. The method adopted is that the ultimate pressure is measured at a specified temperature in a specified form of test dome attached to the inlet of the pump.
