Vacuum Technology Terminology
1 Scope
This document defines the basic terms commonly used in the field of vacuum technology, vacuum pumps and related terms, total pressure and partial pressure vacuum gauge terms, vacuum system
system and related terms, leak detection and related terms, vacuum coating technology terms, vacuum metallurgy terms, and the definitions of the above terms.
This document is applicable to the field of vacuum technology and related teaching, scientific research, design, manufacturing, technical exchanges, as well as the preparation of relevant technical documents and
Books and periodicals.
2 Normative references
This document has no normative references.
3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Basic terminology
3.1.1 General terms
3.1.1.1
Vacuum
A rarefied gas state or environment based on a pressure or molecular density below that of the atmosphere.
3.1.1.2
Vacuum area ranges of vacuum
The division of vacuum areas according to a certain pressure range.
Note 1.The pressure range may vary slightly when selected. The widely recognized typical vacuum range is shown in Table 1.
Note 2.Ground pressure depends on weather conditions and altitude, ranging from 31kPa (the altitude and weather conditions of Mount Everest are the lowest point of air pressure)
to 110kPa (the Dead Sea's altitude and weather conditions are the high point of air pressure).
Table 1 Typical vacuum area
Reasons for defining and dividing pressure ranges (typical situations)
≥1×102Pa~< atmospheric pressure
(31kPa~110kPa)
Low (rough) vacuum
Pressure can be measured through simple materials (such as ordinary steel) and volume
The gas is in a viscous flow state.
≥1×10-1Pa~< 1×102Pa Medium vacuum
Pressure can be measured through precision materials (such as stainless steel) and volumetric
Vacuum pump is obtained; gas is in transition flow state
≥1×10-6Pa~< 1×10-1/Pa High vacuum (HV)
Pressure can pass through precision materials (such as stainless steel), elastomer seals
Seal and high vacuum pump; gas is in molecular flow state
