Abstract

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

This International Standard provides general rules relating to pneumatic systems used in
industrial 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.
