This standard applies to pneumatic systems and their components on machinery. It identifies hazards and factors which affect the safety of systems and their components when they are put to their intended use.Gas bottles and receivers are excluded from the scope of this standard. For receivers see EN 286-1.The principles specified apply to the design, construction and modification of new systems and their components and aspects of use including:- Assembly- Installation- Adjustment- Operation- Cleaning- Maintenance.Components are covered in the standard but only to the extent that safety requirements are given to allow the components to be safely integrated into a system's design.The standard applies to systems and their components on machinery that are manufactured after the date of the adoption of this standard.
