Full definition
Nominal pressure at which a system or component operates under normal design conditions. Always lower than the maximum allowable working pressure (MAWP). Typical values: industrial pneumatics 6-8 bar, pneumatic tools 6.3 bar (ISO 2787), medium hydraulics 100-200 bar, high hydraulics 200-350 bar, ultra-high >350 bar. Safety factor over burst pressure: 4:1 (hoses). CE marking requires PS (maximum allowable pressure) marked on PED components.
