70 - APPENDIX ZZ - MODIFICATIONS TO ISO 4414:1998 FOR APPLICATION IN AUSTRALIA

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.

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.
