10、odies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental a
11、nd non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are d
12、escribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

18、power cylinder. This is a device that converts power into linear mechanical force and motion. It consists of a movable element, e.g. a piston and piston rod, operating within a cylindrical bore.

20、 for interchangeability of commonly used hydraulic cylinders.NOTE 1 This part of ISO 6020 allows manufacturers of hydraulic equipment flexibility in the design of metric cylinders and does not restrict technical development, but does provide basic guidelines.NOTE 2 The compact series dimensions are
21、most applicable to square-head cylinders.This part of ISO 6020 applies only to the dimensions of manufactured products. It does not apply to their functional characteristics.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indisp
