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.

This International Standard specifies a conventional system for identifying fluid power cylinderdimensions and mounting dimensions thereof. Such a system will be composed of:a) a letter code for identifying- mounting dimensions- envelope dimensions- cylinder fitting dimensions;b) a code for identifying cylinder mounting types.This International Standard does not represent a standard list of all cylinder mounting types.The codes indicated in this International Standard are also not to be considered as complete for the development of future interchangeability standards. It establishes uniform descriptions for dimensions and achieves a conformity of language. Although this International Standard presents a code and a method of dimensioning, it is not intended that all dimensions shall be standardized. The same codes can be used for analogous dimensions when this involves neither confusion nor misunderstanding.
