nonUHV
NonUHV is a term used in vacuum technology to describe vacuum conditions that do not meet ultrahigh vacuum (UHV) standards. UHV is typically defined as pressures well below 10^-7 to 10^-9 mbar, depending on the reference. nonUHV encompasses vacuum regimes with higher pressures, including high vacuum and rough vacuum, and can also cover environments approaching atmospheric pressure in certain vessels. The label is practical, signaling that processes may tolerate more contamination, higher outgassing, and simpler materials than UHV requires.
Pressure ranges and measurement: nonUHV regimes generally lie above the UHV threshold, from around 10^-3 mbar
Applications and considerations: nonUHV is common in industrial coating, material processing, packaging, and some analytical or
