Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with sO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2 The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. ISO 21287 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 3, Cylinders. ii BS IS0 21287:2004 Introduction In pneumatic fluid power systems, power is transmitted and controlled through a gas under pressure within a circuit. One component of such system is the pneumatic cylinder. This is a device which converts power into linear force and motion. It consists of a movable element, i.e. a piston, and a piston rod, operating within a cylindrical bore. The compact cylinder series without cushioning allows the application of pneumatic cylinders within systems iv BS ISO 21287:2004 Pneumatic fluid power Cylinders Compact cylinders. 1 000 kPa (10 bar) series, bores from 20 mm to 100 mm Scope This International Standard establishes a metric series of single rod pneumatic compact cylinders with bores of 20 mm to 100 mm for use of at maximum working
