ISO/TC 131/SC 1 - Symbols, terminology and classifications

This document specifies a reference dictionary of standardized product properties for the area of pneumatic fluid power on the basis of ISO 18582-1. The properties are determined on the basis of standardized attributes.

ISO 18582-1:2016 provides the basis for the preparation of a reference dictionary of standardized product properties for the area of fluid power, and for the provision of this reference dictionary and its entire contents in electronic form. ISO 18582-1:2016, based on ISO 13584‑42 and ISO/IEC Guide 77‑2, specifies a reference dictionary of standardized product properties for the area of fluid power. NOTE The properties are determined on the basis of standardized attributes. To ensure optimum unambiguity, the standardized properties are classified into definition classes, forming a so-called standardized "reference hierarchy".

ISO 1219-2:2011 establishes the main rules for drawing hydraulic and pneumatic circuit diagrams using graphical symbols drawn in accordance with ISO 1219-1. ISO 1219-2:2011 also applies to circuit diagrams relating to cooling systems, lubrication systems, cooling lubricant systems and systems of technical gases used in conjunction with fluid power applications.

ISO 1219-1:2012 establishes basic elements for symbols. It specifies rules for devising fluid power symbols for use on components and in circuit diagrams. ISO 1219-1:2012 is a collective application standard of the ISO 14617 series. In ISO 1219-1:2012, the symbols are designed in fixed dimensions to be used directly in data processing systems, which might result in different variants.
