This standard specifies general rules and safety requirements for pneumatic fluid power systems and components. It deals with all significant hazards associated with pneumatic fluid power systems and specifies principles to apply in order to avoid those hazards when the systems are put to their intended use.
Note 1: See Clause 4 and Annex A.
The significant hazard noise is incompletely dealt with in this standard.
Note 2: Noise emission depends especially on the installation of pneumatic components or systems into machinery.
This standard applies to the design, construction and modification of systems and their components, also taking into account the following aspects:
a) assembly;
b) installation;
c) adjustment;
d) uninterrupted system operation;
e) ease and economy of maintenance and cleaning;
f) reliable operation in all intended uses;
g) energy efficiency; and
h) environment.
This standard does not apply to air compressors and the systems associated with air distribution as typically installed in a factory, including gas bottles and receivers.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in ISO 5598 and GB/T 15706 and the following apply.
3.1
commissioning
procedure by which a system is formally accepted by the purchaser
3.2
emergency control
control function that brings a system to a safe condition
3.3
function plate
surface that contains information describing either the performance of a manually operated device (e.g. ON/OFF, forward/reverse, left/right, up/down) or the status of a function performed by the system (e.g. clamp, lift, advance)
3.4
neutral gas
non-combustible gas that has properties similar to air and does not react to the effects of pressure and/or temperature in a manner different from air
3.5
purchaser
party that stipulates the requirements of a machine, equipment, system or component and judges whether the product satisfies those requirements
3.6
supplier
party that contracts to provide the products to satisfy the purchaser's requirements
