5.1 Maximum allowable pressure

x
The whole system must be designed and operated
x
such that the maximum allowable pressure (PS) cannot
x
be exceeded in any part of the system (see name plate
x
details).

Pressure relief valves on receivers (pressure vessels)
x
are absolutely necessary if:
• it is to be expected that the maximum allowable

According to local regulations, additional pressure-limit-
ing safety devices must be provided.
