ISO 1219-1:2006 establishes basic elements for symbols. It lays down rules for devising fluid power symbols for use on components and in circuit diagrams.
ISO 1219-1:2006 is a collective application standard of the ISO 14617 series. In this series of International Standards, the symbols are designed in fixed dimensions to be used directly in data processing systems, which might result in different variants.
In addition to terms in English and French, two of the three official ISO languages, ISO 1219-1:2006 also gives the equivalent terms in German.
