ISO 18582-2:2018

Overview

ISO 18582-2:2018 - Fluid power - Specification of reference dictionary - Part 2: Definitions of classes and properties of pneumatics is a standardized reference dictionary for pneumatic fluid‑power product properties. Building on ISO 18582-1, this part defines classes, property names and their meanings for pneumatic components and systems so manufacturers, engineers and software systems can describe products consistently and unambiguously.

Key topics and technical requirements

This standard focuses on defining standardized product properties and their attributes for pneumatics. Major topic areas covered include:

• General principles, terms and definitions for a reference dictionary of pneumatic properties.
• Component and system classes (e.g., general fluid systems and components for pneumatics).
• A comprehensive list of properties and property identifiers, such as:
  • Pressure-related properties (initial/final measuring range, maximum/minimum operating and output pressure, pilot pressure, vacuum limits)
  • Time and dynamic performance (shifting time, shifting‑on/off time, maximum piston speed)
  • Mechanical dimensions and movement (stroke, piston diameter, swivel angle, moving mass)
  • Ports and connections (number and type of pneumatic input/output/exhaust/pilot ports)
  • Sealing, mounting and actuator details (sealing principle, piston rod type, shaft end)
  • Flow and conductance (sonic conductance, volumetric flow rates)
  • Filtration and air quality (grade of filtration, filter efficiency, compressed air quality classes)
  • Environmental and safety attributes (maximum/minimum ambient and medium temperatures, IP protection class, RoHS conformity, certification)
  • Functional and performance descriptors (valve functions, control characteristics, noise reduction, gripping force/torque, clamping area)
• Application classes for grouping pneumatic items by use.

Note: ISO 18582-2 defines names and definitions for properties rather than prescribing numeric values or test methods.

Practical applications - who uses it and why

ISO 18582-2 is useful for:

• Manufacturers and product managers: to create consistent product catalogs and data sheets.
• Design and systems engineers: for unambiguous specification of pneumatic components in system designs.
• Procurement and OEMs: to compare products across suppliers using standardized property names.
• Software vendors and PLM/ERP integrators: to enable reliable product data exchange, BOM management and digital catalogs.
• Standards committees and test labs: to harmonize terminology and classification.

Using this dictionary improves interoperability, reduces specification errors, and accelerates digital data exchange in automation, factory equipment, robotics and general industrial pneumatics.
