Pressure for which devices or systems are calculated under defined conditions to obtain functionality (see also DIN 2401, Part 1).
The calculated pressure can be definitive for the operating pressure (corresponds to the actual pressure) or also be a measure for the maximum permissible operating (over)pressure up to which devices, installations or components are allowed to be operated.
The calculated pressure corresponds to the rated value in accordance with DIN 40 200 (DIN 24 312).
