ISO 18582-1:2016

Overview

ISO 18582-1:2016 - Fluid power - Specification of reference dictionary - Part 1: General overview on organization and structure - defines the organizational model and structure for a standardized, electronic reference dictionary of product properties for the fluid power domain (hydraulics and pneumatics). It sets the principles for preparing a machine‑readable, unambiguous set of standardized product properties so that product data can be exchanged and reused across CAD, ERP, e‑catalogues and other systems without conversion errors.

Key topics and technical requirements

• Reference dictionary model: Specifies a hierarchical approach that separates definition classes (where properties are defined) from application classes (where properties are applied to real objects).
• Compatibility and foundations: Based on ISO 13584‑42 (parts library methodology) and ISO/IEC Guide 77‑2 (product properties and classes), and aligns with ISO 80000 for quantities and units.
• Attribute sets for properties and classes: Defines mandatory and optional attributes used to describe properties and classes. Examples of mandatory attributes for properties include:
  • Code, Version, Definition class, Preferred name, Definition, Domain Examples of class attributes include Code, Version, Information supplier, Preferred name, Definition, Superclass.
• Reference hierarchy: Introduces a standardized “reference hierarchy” to ensure unambiguous property definitions and inheritance rules across hierarchies.
• Electronic delivery: Emphasizes that the entire dictionary and its contents should be made available in electronic form for direct import into user systems.

Applications and who uses it

ISO 18582-1:2016 is practical for organizations and professionals who need accurate, interoperable product data in the fluid power sector:

• Hydraulic and pneumatic component manufacturers and suppliers
• Product data managers and catalog providers (e‑catalogues, marketplaces)
• Systems integrators, CAD and PLM/ERP software vendors
• Procurement teams and OEMs requiring consistent product descriptions across the supply chain
• Standards committees and technical authors preparing Parts 2 and 3 of ISO 18582

Benefits include improved e‑business interoperability, reduced data conversion errors, faster product development and streamlined supplier–customer data exchange.
