ISO 3529-2:2020

Overview

ISO 3529-2:2020 is an internationally recognized standard that provides comprehensive vocabulary and definitions related to vacuum pumps and their associated terms. As a continuation of ISO 3529-1, which addresses general vacuum technology terms, this second part focuses specifically on the classification, types, parts, and characteristics of vacuum pumps. Developed by ISO Technical Committee ISO/TC 112 on Vacuum technology, this updated document serves as a critical reference for manufacturers, engineers, and users engaged in vacuum pump selection, operation, and research.

The standard addresses modern vacuum pump technologies, including various types of positive displacement and kinetic vacuum pumps, ensuring clarity and uniformity in terminology globally.

Key Topics

• Vacuum Pump Definitions
  ISO 3529-2 defines a vacuum pump as a device for creating, improving, or maintaining a vacuum. It divides vacuum pumps primarily into two categories: gas transfer pumps (which move gas molecules mechanically) and gas gathering pumps (which capture gases by physical or chemical means).

• Types of Vacuum Pumps
  The standard introduces detailed definitions for numerous vacuum pump types including but not limited to:

  • Positive displacement pumps such as diaphragm, piston, scroll, rotary vane, liquid ring, roots, screw, claw, and trochoid vacuum pumps.
  • Kinetic vacuum pumps including turbine, regenerative, molecular drag, turbo-molecular, diffusion, ejector (liquid jet, gas jet, vapor jet), and ion transfer pumps.
  • Gas entrapment or capture pumps like adsorption, getter, non-evaporable getter (NEG), sublimation, and sputter ion vacuum pumps.

• Parts and Accessories
  Unique parts and accessories related to vacuum pumps are covered to standardize terminology associated with pump components, such as inlets, outlets, rotors, valves, and sealing mechanisms.

• Operational Categories and Characteristics
  The document further classifies vacuum pumps based on operational principles and characteristics, providing a clear framework for understanding pump performance and suitable applications.

• Annex A: Classification Table
  A helpful informative annex provides a classification table summarizing various vacuum pump types according to their operational features and design principles.

Applications

ISO 3529-2:2020 serves as an essential reference for industries and technology sectors reliant on vacuum technology, including:

• Industrial Vacuum Systems
  Facilitates uniform communication about vacuum pumps in manufacturing processes such as semiconductor fabrication, metallurgy, and chemical processing.

• Scientific Research
  Supports laboratories requiring precise vacuum technology for experiments, ensuring consistent understanding of pump types and characteristics.

• Equipment Design and Maintenance
  Assists designers and maintenance personnel in selecting appropriate vacuum pumps and understanding parts for troubleshooting and repair.

• Education and Training
  Provides a standardized vocabulary that helps instructors and students grasp the nuances of vacuum pumps and their operation.

Employing this standard helps reduce misunderstandings and technical ambiguities surrounding vacuum pump technology, enhancing efficiency and safety in vacuum system applications.
