10、f national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. In

11、ternational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with

12、the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval

13、 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17613-1 was prepared by Technical Committe

26、R), with minimum recommended size of borewell/tubewell (d) is given in Table 1. Table 1 Recommended minimum diameter of borewell/tubewell Static water level (SWL) range Minimum borewell/tubewell diameter R d Borewell/tubewell size classification m mm Shallow 0 R 6 40 Medium 6 u R 15 100 Deepwell 15

27、u R 40 100 Extra-deepwell R W 40 100 BS ISO 17613-1:200634.2 Type classification The type classification of manually operated pumps shall be specified as follows, depending on the type of action involved: a) reciprocating; b) lever-operated; c) direct-acting; d) rotary: 1) double acting, 2) quadrupl

28、e acting; e) hydraulic; f) any combination of above. 5 Construction and dimensions The pump base (stand or pedestal) shall be constructed in a workmanlike manner and to dimensions not less than those shown in Figures A.1 to A.7. When installed over the borehole, the pump base shall be grouted with a

29、 waterproof grout such that surface level leakage does not re-enter the bore hole. 6 Requirements Unless otherwise specified, tolerances for linear and angular dimensions (including fillet radii and chamfer height) for all manufactured components shall conform to the tolerances as per Class m (mediu

30、m) of ISO 2768-1:1989. The tolerance of metric threads shall conform to the requirements of ISO 965-1 and ISO 965-2, Class 6g for bolts and Class 6H for nuts. The raw materials used for manufacturing pump components coming in contact with water shall not contain any material that is harmful or that

31、can be detrimental to the quality of water being pumped. Typically, austenitic stainless steel should be used. It is recommended to use stainless steel connecting rods where water has an ion content exceeding 1 mg/l or a pH value less than 6,5. All the components shall be free from sharp edges/corne

32、rs, burrs and other surface defects. Welding shall conform to the requirements of ISO 9692-1 and ISO 15609-1. For stainless steel components welded by manual arc welding, suitable electrodes conforming to the requirements of ISO 3581 shall be used. Unless otherwise specified, the minimum specified t

33、hickness of the member to be welded shall be the guiding factor for deciding the weld fillet size. The fillet shall normally be not less than the minimum specified thickness of the member to be welded. Polytetrafluoroethylene (PTFE) tape or equivalent shall be used on the metal riser pipe threaded j

Paint used on the pump components shall not be of the marine anti-fouling type. 8 Testing 8.1 Visual

37、tests All the pumps shall be examined for finish and visual defects. 8.2 Dimensional and other tests Unless otherwise specified in the contract or order, the procedure given in ISO 2859-1 shall be followed for sampling inspection. For the characteristics dictated in 8.3, 8.4 and 8.5, a single sampli

38、ng plan with general inspection level I and an acceptance quality level (AQL) of 1 % as given in Table I and II-A of ISO 2859-1:1999 shall be followed. When required the manufacturer shall produce test certificates for the component raw materials. The pumping element shall be checked for water leaka

39、ge using a 0,2 MPa (2 bar) hydrostatic pressure applied for 10 min. The pressure is to be measured using a previously calibrated pressure gauge capable of reading from 0 MPa to 0,5 MPa (0 bar to 5 bar). No leakage from the pumping element shall be observed. A sample pump shall be tested for discharg

40、e at the specified operating conditions at the manufacturers works. The discharge measured shall not be less than that guaranteed by the supplier. 8.3 Routine tests Two complete pumps from the selected lot shall be subjected to a discharge test in addition to the tests required in 8.2. The pump shal

41、l be primed and the test shall start only after getting continuous flow of water through the pump outlet. The water shall then be collected in a container for a number of continuous cycles as specified by the pump manufacture to be completed in one minute. The water level (lift) shall be the maximum

42、 given in Table 1 for the classification. BS ISO 17613-1:20065The discharge thus measured shall not be less than the discharge guaranteed by the supplier. 8.4 Type testing A sample pump shall be operated for 4 000 h, with the help of some mechanical device or otherwise at the operating conditions sp

43、ecified by the manufacturer but with the water level (lift) at the maximum given in Table 1 for the classification. The force exerted by the operator to operate the pump shall not exceed 150 N and the range of movement of the operating arm shall lie between 0,65 m to 0,85 m above the level of the op

44、erators feet. This test shall be repeated after the 4 000 h test. The discharge shall be measured and recorded after every 24 h of pumping. At the conclusion of the test, the variation between the maximum and the minimum discharge reading shall not be more than 5 %. At the end of the type test, the

45、pump shall be opened and critical components examined for abnormal wear or other damage. The manufacturer shall provide a list of the pumps critical components to the testing authority. The type test shall be repeated if any major design change is carried out. 8.5 Conformity criteria The pump lot sh

46、all be considered to conform to the requirements of the specification if the pumps tested are selected in accordance with the requirements of 8.2 and conform to the following requirements: a) the number of pumps meeting the requirements of a characteristic inspected under 8.2 shall exceed the corres

47、ponding acceptance number as specified in ISO 2859-1; b) the pumps selected according to 8.3 meet the requirements as given in 8.3; c) the pump type test complies with the requirements of type test described in 8.4 and the examination shows no abnormal wear. 9 Marking The pump head assembly shall ha
