ISO 5598 standard is for Fluid power systems and components — Vocabulary ISO 5598 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 1, Terminology, classification and symbols.
Introduction of ISO 5598
In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within a circuit.
The purpose of this vocabulary is
to provide pertinent terms having a specific meaning in fluid power technology,
to include common dictionary or engineering terms only when they are a generic root for a series of terms specific to fluid power technology,
to refer synonymous terms to the preferred term,
to list deprecated terms, but to define and clearly mark these terms as such and to indicate the preferred term.
This International Standard conforms to the requirements of ISO 10241 on the preparation and layout of international terminology standards.
The following conventions are used:
(deprecated) indicates that a term should no longer be used;
hydraulic indicates that the term relates only to hydraulic technology;
pneumatic indicates that the term relates only to pneumatic technology;

In the French and German texts, "m" indicates words of masculine gender; "f" indicates words of feminine gender; and "n" indicates words of neutral gender.
