    23、main dimensions The nominal duty point and main dimensions appropriate to the relevant pump designation shall be as given inTable 1 and as illustrated in Figure 1. Figure 1 illustrates a pictorial representation of an end suction centrifugal pump. Pumps to this standard do not need to correspond to

    24、this pictorial representation; only the dimensions and direction of rotation are to be as specified. 4 Hydrostatic pressure test Hydrostatic pressure test is an internal pressure test using water. Hydrostatic test pressure shall be1,3 times the maximum discharge pressure but shall not exceed13 bar.

    25、The relation between cold test pressure and hot operating pressure or extreme cold operating pressure, shall be the subject of agreements between purchaser and manufacturer. 5 Designation system Centrifugal pumps in accordance with this standard shall be designated as follows. The designation incorp
