Pump Speed Information
The pumping speed of capture technology vacuum pumps is measured according to ISO/DIS 3556-1-1992.
Key points to note in this specification include:
- The ion pump is required to be fully saturated after pressure stabilization.
- There is no method provided for testing ion pumps in an unsaturated state.
- This method does not allow for testing of ion pumps below 10 l/s.
- This test method specifically calls for the use of nitrogen and is subject to interpretation for other gases.
