ISO 3529 is a series on vacuum technology. Vacuum technology deals with technological processes and equipment that use a vacuum to achieve better results than those that run under atmospheric pressure. ISO 3529‑1 defines general terms used in vacuum technology. ISO 3529‑1 gives theoretical definitions as precise as possible, bearing in mind the need for use of the concept in practice.
ISO 3529‑1 on vacuum technology is useful for:
Vacuum systems usually consist of gauges, vapour jet and pumps, vapour traps and valves along with other extensional piping. A vessel that is operating under a vacuum system may be any of these types such as a processing tank, steam simulator, particle accelerator, or any other type of space that has an enclosed chamber to maintain the system in less than atmospheric gas pressure. ISO 3529‑1 discusses general terms like a vacuum, ranges of vacuum, ultra-clean vacuum, the pressure of a vacuum, the pressure of a vacuum, partial pressure and total pressure which gives specifications on the vacuum technology.
ISO 3529‑1 also defines the terms to define gases and vapours and their parameters, terms needed to characterize the movement of gas molecules and the flow of gases and terms to define the surface and bulk effects in vacuum technology that helps you understand the concept of vacuum technology and helps in the practice. Using ISO 3529‑1 you can define general terms used in vacuum technology.
BS ISO 3529‑1:2019 supersedes ISO 3529-1:1981. BS ISO 3529‑1:2019 includes some technical changes with respect to ISO 3529-1:1981. These include:
