This third edition cancels and replaces the second edition (ISO 44 14:1998), which has been technically revised, specifically with regards to the following:
a) integration of ISO 4414:1998 and EN 983:1996;
b) integration of safety requirements to comply with the European Machinery Directive 2006/42/EC;
c) updating of safety requirements, taking into account International Standards on machine safety.
This International Standard is a type B standard as defined in ISO 12100. The stipulations of this International Standard can be supplemented or modified by a type C standard. For machines that are covered by the scope of a type C standard and that have been designed and built in accordance with the provisions of that standard, the provisions of that type C standard take precedence over the provisions of this type B standard.
In pneumatic fluid power systems, power is transmitted and controlled through air or a neutral gas under pressure within a circuit.
The application of pneumatic fluid power systems requires a thorough understanding and precise communication between the supplier and purchaser. This International Standard was prepared to assist that understanding and communication and to document many of the good practices learned from experience with pneumatic systems.
Use of this International Standard assists in
a) identifying and specifying the requirements for pneumatic systems and components;
b) identifying respective areas of responsibility;
c) designing systems and their components to comply with specific requirements;
This International Standard specifies general rules and safety requirements for pneumatic fluid power systems and components used on machinery as defined by ISO 12100:2010, 3.1. 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 International Standard.
NOTE 2 Noise emission depends especially on the installation of pneumatic components or systems into machnery.
This International 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 International 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.
