Operating pressure PS
Directive 97/23/ EC of the Council of April 29, 1999 on mobile pressurized equipment (Directive for
Pressure Equipment) is applied. The maximum permissible operating pressure PS is calculated for the
maximum operating temperature TS. Both limits (PS and TS) are listed on the rating plate. As a rule PS
corresponds to the nominal pressure of the connection.
Pressure Tested PT
The pressure tested is calculated in accordance with the Directive for Pressure Equipment (97/23/EC) or AD
2000-HP30 under consideration of the maximum permissible operating pressure as well as the maximum
operating temperature.
