This part of ISO 1219 establishes basic elements for symbols. It specifies rules for devising fluid power symbols for use on components and in circuit diagrams. This part of ISO 1219 is a collective application standard of the ISO 14617 series. In this part of ISO 1219, the symbols are designed in fixed dimensions to be used directly in data processing systems, which might result in different variants. NOTE In addition to terms in English and French, two of the three official ISO languages, this part of ISO 1219 gives the equivalent terms in German; these are published under the responsibility of the member body for Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
