This International Standard establishes a metric series of mounting dimensions required for interchangeability of commonly used pneumatic cylinders for a maximum working pressure of 1 000 kPa (10 bar). It applies to pneumatic cylinders with detachable mountings. Notes 1 This International Standard allows manufacturers of pneumatic equipment freedom of design in metric cylinders and does not restrict technical development but provides basic guidelines. 2 ISO 6430 deals with cylinders for which mountings are integrated in the main body of the device.
