AS 2821-1985

Adopted from and identical with ISO 6099. It specifies a conventional system for identifying fluid power cylinder dimensions and mounting dimensions. The system is composed of a letter code for identifying mounting dimensions, envelope dimensions, and cylinder fitting dimensions as well as a code for identifying cylinder mounting types. It does not represent a standard list of all cylinder mounting types but it does establish uniform descriptions for dimensions and a conformity of terms. The codes are not complete as allowance is provided for future development.
