5、Volumetric expansion test of gas bottles:
The water pressure in the cylinder shall be increased at a controlled rate until the test pressure, ph, is reached within a measuring tolerance of 0/+3 % or +10 bar, whichever is the lower.
The cylinder shall remain under pressure, ph, for at least 30 s and the total volumetric expansion measured. The pressure shall then be released and the volumetric expansion re-measured.
The cylinder shall be rejected if it shows a permanent expansion (i.e. volumetric expansion after the pressure has been released) in excess of 10 % of the total volumetric expansion measured at the test pressure, ph.
The total and permanent expansion readings shall be recorded, together with the corresponding serial number of each cylinder tested, so that the elastic expansion (i.e. total expansion less permanent expansion) under the test pressure can be established for each cylinder.
