Scope

This part of GB/T 40344 specifies the measurement methods for the volumetric flow rate, base pressure, water vapor tolerance, power consumption, and minimum starting temperature of volume vacuum pumps that directly discharge into the atmosphere and typically have a base pressure lower than 10 kPa. In this part, it is necessary to use the methods specified in GB/T 40344.1 to determine the volumetric flow rate and base pressure. This part is also applicable to other pumps that directly discharge into the atmosphere, such as traction pumps.
