Pressure-control systems are required to be installed where the source of supply makes it possible for the piping to be pressurized above its operating pressure. Such systems are required to operate at or below the maximum operating pressure of the piping. It has been clarified that piping is not to be intentionally operated at pressures greater than its maximum operating pressure.
In 1999, it became permissible for the maximum operating pressure of piping with a maximum operating pressure of 350 kPa or less to be exceeded by up to 35 kPa, in recognition of the difficulty of limiting pressures at such low pressure levels.
