- Scope
- This standard specifies the determination of critical front pressure of vapor flow vacuum pumps. This standard applies to vapor flow pumps using oil or mercury as the working fluid, including diffusion pumps, jet pumps, and diffusion jet pumps, that is, oil booster pumps (the pumps can work in the molecular flow and laminar flow ranges, with diffusion pumps and jet pumps). combined performance). The three types of vapor flow pumps are hereinafter referred to as pumps. These pumps are available with or without baffles or cold traps.
