This European Standard has been prepared by SC 4, Rotodynamic pumps, of CEN/TC 197, Pumps, of which the Secretariat is held by DIN, based on a proposal document, CEN/TC 197/SC N 22, submitted by the European Committee of Pump Manufacturers (EUROPUMP) in December 1990 and was adopted for CEN enquiry at the meeting of CEN/TC 197/SC on 1991-03-14 in Frankfurt This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 1995, and conflicting national standards shall be withdrawn at the latest by October 1995 In accordance with the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany,

EN 733:1995 Scope Hydrostatic pressure test This European Standard specifies the designations, nominal duty points and main dimensions of end-suction centrifugal pumps rated at 10 bar Hydrostatic pressure test is an internal pressure test using water Hydrostatic test pressure shall be 1,3 times the maximum discharge pressure but shall not exceed 13 bar 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 NOTE Depending on special circumstances e.g temperature, materials, sealing of the shafts etc., excess operating pressure need not attain the value of the nominal pressure under any circumstances Normative references This European Standard incorporates by dated or undated reference, provisions from other publications These normative references are cited at the appropriate place in the text and the publications are listed hereafter For dated references,
