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 machinery. 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.
