    Abstract - (Show below) - (Hide below)

    Specifies requirements for the design and manufacture of pneumatic fluid power systems. This Standard is an adoption with Australian modifications and has been reproduced from ISO 4414:1998.

    Scope - (Show below) - (Hide below)

    This International Standard provides general rules relating to pneumatic systems used inindustrial manufacturing processes. It is intended as a guide for both suppliers and purchasers, with a view to ensuring:a) safety;b) uninterrupted system operation;c) ease and economy of maintenance;d) long life of the system.This International Standard does not apply to air compressors and the systems associated with air distribution as typically installed in a factory.
