Pump construction and performance
4.1 Connections Inlet, outlet and threaded connections shall be in accordance with appropriate National or International standards.
4.2 Pump casing strength The maximum allowable casing working pressure (see EN12723) shall be at least 10 bar and shall be at least equal to the maximum closed valve pressure at maximum rotational speed and maximum impeller diameter plus maximum inlet pressure.
4.3 Construction 4.3.1 All functioning parts or structural components vital to a pumps operation shall be capable of being maintained or replaced. Note 1: Whatever method is adopted, it should permit ready maintenance with a minimum of downtime. Note 2: The interchangeability of parts shall be ensured by the use of standardized tolerances. Note 3: Bearings, shaft packing and also the clearance of rotating parts should be designed so that the pump is capable of operating efficiently even after being static for long periods in the stand-by condition. 4.3.2 Casing wear rings shall be fitted and shall be prevented from rotating. 4.3.3 The pump casing shall be made from grey cast iron or at least an equivalent metal. Internal pump shafts, protective sleeves for shafts, metal parts of mechanical seals, impellers, impeller fastenings (impeller nuts, locking plates or washers and adjusting springs) and wear rings, including their counterparts shall be made from bronze, stainless steel or at least an equivalent metal. 4.3.4 The diameter of the portion of the shaft or shaft sleeve (where fitted) in contact with shaft seals shall be in accordance with ISO 3069.
4.3.5 The supplier shall provide detailed shaft stress calculations which show that the shaft is suitable for the maximum impeller diameter at 105% the maximum rated speed.
Page 7 prEN 12259-12:2004
4.3.6 Shaft driven pumps shall use mechanical seals or soft packing. 4.3.7 Shaft seal cavity dimensions shall be in accordance with ISO 3069. 4.3.8 Means shall be provided for repacking stuffing boxes without removing or dismantling any part other than gland components and/or guards.
4.4 Rotational speed The rated speed shall be specified by the pump supplier but shall not exceed 3,600 1/min. The maximum allowable continuous speed shall be at least 105% of the rated speed.
4.5 Characteristic curves 4.5.1 The H(Q) characteristic curve of sprinkler pumps shall be stable (see Annex B). The measurement uncertainty as specified in EN ISO 9906 Grade 2 may be applied. 4.5.2 Within the pump design range the NPSHR by the pump shall not exceed 5 m or in the case of submersible pumps 8.5 m. The criterion for NPSHR is 3 % drop in total differential head for the first stage of multi-stage pumps or for single-stage pumps with constant speed and a fixed rate of flow. 4.5.3 The flow, power consumption, NPSHR and the corresponding delivery head shall be determined in accordance with ISO 9906 Grade 2. 4.5.4 The pump manufacturer shall specify the minimum by-pass flow value to mitigate the possibility of pump failure in the closed valve condition. The minimum flow shall be demonstrated by test as specified in 5.3.
5
Type Approval Tests
5.1 Hydrostatic pressure tests 5.1.1 Leakage test Examine the pump for leakage in accordance with EN12162 :2001. The hydrostatic test pressure (ptest) shall be calculated assuming the product of the factors (K1 x K2) is at least 1.5. Maintain the hydrostatic test pressure for a duration of 10 minutes. 5.1.2 Rupture test Examine the pump casing for resistance to pressure using the test methods described in EN12162 :2001. The hydrostatic test pressure (ptest) shall be calculated assuming the product of the factors (K1 x K2) is at least 2. Maintain the test pressure for a duration of 10 minutes. The pump casing shall withstand the hydrostatic pressure test without rupture.
Page 8 prEN 12259-12:2004 Note: Leakage from joints shall be disregarded.
5.2 Main tests Type approval tests and conversion of test data shall be undertaken using methods defined in ISO 9906 : 1999 Grade 2 and the tolerances given there. Pumps shall be tested with a range of impeller diameters, which shall include the maximum and minimum impeller diameters. Performance between tested impeller diameters may be interpolated in accordance with ISO 9906: 1999 Annex B for changes not exceeding ± 4% in impeller diameter. The test data required for the purpose of evaluation in accordance with ISO 9906: 1999, are established at a minimum of 7 points uniformly distributed between the pump minimum flow and the highest rate of flow to be measured. NPSHR shall be determined for minimum and maximum impeller diameters and speeds at 5 points between 0,3 Qz and highest rate of flow. The highest flow to be measured shall be sufficient to demonstrate a non-overloading power characteristic or a flow corresponding to at least NPSHR of 16m. Pumps intended for use in HHP or HHS pre-calculated systems shall be tested to at least 140% of the design flow where it shall be demonstrated that the total differential head is at least 70% of the total differential head at the design flow. Pump characteristic curve conversions for alternative drivers with differing speeds shall be converted using the formula: (Ref ISO 9906: 1999).
n ( NPSHR)T = ( NPSHR) sp n
x
The test to verify the validity of the above formula shall entail measuring the NPSHR value for the lowest and highest intended speed.
5.3 Minimum flow The pump shall be run for a minimum of 2 hours with the maximum impeller diameter at maximum speed and the minimum flow specified by the supplier. The pump inlet and outlet temperatures shall be measured throughout the test. The maximum water temperature rise across the pump shall not exceed 10 ºC for the duration of the test. Measure the head, flow rate and power input throughout the test at intervals of not exceeding 15 minutes. During the test the power input shall not increase by more than 2%, and the head shall not decrease by more than 1.5%

The documents shall make it clear that the above requirements have been met. Where the requirements of Annex ZA.3 give the same information as above, the requirements of this clause (5) shall be considered to have been met.
7
Evaluation of conformity
7.1 General The compliance of the component with the requirements of this European Standard shall be demonstrated by: initial type testing, factory production control by the manufacturer. NOTE The manufacturer is a natural or legal person, who places the component on the market under his own name. Normally, the manufacturer designs and manufactures the component himself. As a first alternative, he may have it designed, manufactured, assembled, packed, processed or labeled by subcontracting. As a second alternative he may assemble, pack, process, or label ready-made products.
Page 11 prEN 12259-12:2004 The manufacturer shall ensure: that the initial type testing in accordance with this European Standard is initiated and carried out (where relevant, under the control of a product certification body); and that the component continuously complies with the initial type testing samples, for which compliance with this European Standard has been verified. He shall always retain the overall control and shall have the necessary competence to take the responsibility for the component. The manufacturer shall be fully responsible for the conformity of that component to all relevant regulatory requirements. However, where the manufacturer uses components already shown to conform to those requirements relevant for that component (e.g. by CE marking) the manufacturer is not required to repeat the evaluation which led to such conformity. Where the manufacturer uses components not already shown to conform, it is his responsibility to undertake the necessary evaluation to show conformity.
7.2
Initial type testing
7.2.1 Initial type testing in accordance with clause 5 shall be performed to demonstrate conformity with this European Standard, except as described in 7.2.3 to 7.2.4. All characteristics given in clause 4, except 4.1 and 4.3.5, shall be subject to this initial type testing, except as described in 7.2.3 to 7.2.4. 7.2.2 In the case of modification of the component or of the method of production (where these may affect the stated properties), initial type testing shall be performed. All tests given in clause 5, the results of which may be influenced by the modification, shall be performed, except as described in 7.2.3 to 7.2.4. All characteristics given in clause 4, except 4.1 and 4.3.5, which may be changed by the modification, shall be subject to this initial type testing, except as described in 7.2.3 to 7.2.4. 7.2.3 Tests previously performed in accordance with the provisions of this standard may be taken into account providing that they were made to the same or a more rigorous test method under the same system of attestation of conformity on the same component or components of similar design, construction and functionality, such that the results are applicable to the component in question. NOTE Same system of attestation of conformity means testing by an independent third party under the control of a product certification body. 7.2.4 Components may be grouped into families where one or more characteristics are the same for all components within that family or the test results are representative of all components within that family. In this case not all components of the family have to be tested for the purposes of the initial type testing. 7.2.5 Test samples shall be representative of the normal production. If the test samples are prototypes, they shall be representative of the intended future production and shall be selected by the manufacturer. NOTE In the case of prototypes and third party certification, this means that it is the manufacturer not the third party who is responsible for selecting the samples. During the initial inspection of the factory and of the factory production control (see 7.3), it is verified that the component continuously complies with the initial type testing samples.
Page 12 prEN 12259-12:2004 7.2.6 If the technical documentation of the test samples does not give a sufficient basis for later compliance checks, a reference sample (identified and marked) shall remain available for this purpose. NOTE Later compliance checks are possible, if the test laboratory holds an assembly drawing with parts list and this parts list refers to the necessary detail drawings and these detail drawings are available at the factory. 7.2.7 Any initial type testing and its results shall be documented in a test report.
7.3 Factory production control (FPC) 7.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the components placed on the market conform with the stated performance characteristics. If the manufacturer has the component designed, manufactured, assembled, packed, processed and labeled by subcontracting, FPC of the subcontractor may be taken into account. Where subcontracting takes place, the manufacturer shall retain the overall control of the component and ensure that he receives all the information that is necessary to fulfill his responsibilities according to this European Standard. The manufacturer who subcontracts all of his activities may in no circumstances discharge himself of his responsibilities to a subcontractor. FPC is the permanent internal control of production exercised by the manufacturer. All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of conformity evaluation and enable the achievement of the required component characteristics and the effective operation of the production control system to be checked. Factory production control therefore brings together operational techniques and all measures allowing maintenance and control of the conformity of the component with its technical specifications. Its implementation may be achieved by controls and tests on measuring equipment, raw materials and constituents, processes, machines and manufacturing equipment and finished components, including material properties in components, and by making use of the results thus obtained. 7.3.2
General requirements
The FPC system shall fulfill the requirements as described in the following clauses of EN ISO 9001:2000, where applicable: 4.2 except 4.2.1 a) 5.1 e), 5.5.1, 5.5.2 clause 6 7.1 except 7.1 a), 7.2.3 c), 7.4, 7.5, 7.6 8.2.3, 8.2.4, 8.3, 8.5.2 The FPC system may be part of a Quality Management system, e.g. in accordance with EN ISO 9001:2000.
Page 13 prEN 12259-12:2004 7.3.2 Component specific requirements 7.3.3.1 The FPC system shall: address this European Standard; and ensure that the components placed on the market conform with the stated performance characteristics. 7.3.3.2 The FPC system shall include a component specific FPC- or Quality-plan, which identifies procedures to demonstrate conformity of the component at appropriate stages, i.e. a) the controls and tests to be carried out prior to and/or during manufacture according to a frequency laid down; and/or b) the verifications and tests to be carried out on finished components according to a frequency laid down; and c) leakage tests on each pump in accordance with EN12162 with the hydrostatic test pressure (ptest) calculated assuming the product of the factors (K1 x K2) equals 1.5. If the manufacturer uses finished components, the operations under b) shall lead to an equivalent level of conformity of the component as if normal FPC had been carried out during the production. If the manufacturer carries out parts of the production himself, the operations under b) may be reduced and partly replaced by operations under a). Generally, the more parts of the production are carried out by the manufacturer, the more operations under b) may be replaced by operations under a). In any case the operation shall lead to an equivalent level of conformity of the component as if normal FPC had been carried out during the production. NOTE Depending on the specific case, it may be necessary to carry out the operations referred to under a) and b), only the operations under a) or only those under b). The operations under a) centre as much on the intermediate states of the component as on manufacturing machines and their adjustment, and measuring equipment etc. These controls and tests and their frequency are chosen based on component type and composition, the manufacturing process and its complexity, the sensitivity of component features to variations in manufacturing parameters etc. The manufacturer shall establish and maintain records which provide evidence that the production has been sampled and tested. These records shall show clearly whether the production has satisfied the defined acceptance criteria and shall be available at least for ten years. Where the component fails to satisfy the acceptance measures, the provisions for non-conforming products shall apply, the necessary corrective action shall immediately be taken and the components or batches not conforming shall be isolated and properly identified. Once the fault has been corrected, the test or verification in question shall be repeated. The results of controls and tests shall be properly recorded. The component description, date of manufacture, test method adopted, test results and acceptance criteria shall be entered in the records under the signature of the person responsible for the control/test. With regard to any control result not meeting the requirements of this European Standard, the corrective measures taken to rectify the situation (e.g. a further test carried out, modification of manufacturing process, throwing away or putting right of the component) shall be indicated in the records. 7.3.3.3 Individual components or batches of components and the related manufacturing documentation shall be completely identifiable and retraceable. 7.3.4
Initial inspection of factory and FPC
7.3.4.1 Initial inspection of factory and FPC shall generally be carried out when the production is already running and the FPC is already in practice. It is, however, possible that the initial inspection of factory and FPC is carried out before the production is already running and/or before the FPC is already in practice.
Page 14 prEN 12259-12:2004
7.3.4.2 The following shall be assessed to verify that the requirements of 7.3.2 and 7.3.3 are fulfilled: the FPC-documentation; and the factory. In the assessment of the factory it shall be verified: a) that all resources necessary for the achievement of the component characteristics required by this European Standard are or will be (see 7.3.4.1) available; and b) that the FPC-procedures in accordance with the FPC-documentation are or will be (see 7.3.4.1) implemented and followed in practice; and c) that the component complies or will comply (see 7.3.4.1) with the initial type testing samples, for which compliance with this European Standard has been verified; and d) whether the FPC system is part of a Quality Management system in accordance with EN ISO 9001:2000 (see 7.3.2) and as part of this Quality Management system is certified and has yearly surveillance by a certification body, who is recognised by an accreditation body which is member of the “European Co-operation for Accreditation” and which has signed the “Multilateral agreement” (MLA) there. 7.3.4.3 All factories of the manufacturer, where for the relevant component final assembling or at least final testing is performed, shall be assessed to verify that the conditions of 7.3.4.2 a) to c) are in place. One assessment may cover one or more components, production lines and/or production processes. If the FPC system covers more than one component, production line or production process, and if it is verified that the general requirements are fulfilled then the detailed verification of the component specific FPC requirements for one component may be taken as representative of the FPC of other components. 7.3.4.4 Assessments previously performed in accordance with the provisions of this standard may be taken into account providing that they were made to the same system of attestation of conformity on the same component or components of similar design, construction and functionality, such that the results may be considered applicable to the component in question. NOTE Same system of attestation of conformity means inspection of FPC by an independent third party under the control of a product certification body. 7.3.4.5 Any assessment and its results shall be documented in a report. 7.3.5
Continuous surveillance of FPC
7.3.5.1 All factories which have been assessed according to 7.3.4 shall be re-assessed once a year, except as stated in 7.3.5.2. In this case each FPC assessment shall verify a different component or production process, where applicable. 7.3.5.2 If the manufacturer provides proof of continuing satisfactory operation of his FPC system the frequency of the re-assessment may be reduced to once every four years. NOTE 1 Sufficient proof can be the report of a certification body, see 7.3.4.2 d). NOTE 2 If the overall Quality Management system in accordance with EN ISO 9001:2000 is well implemented (verified in the initial assessment of factory and FPC) and continuously practised (verified in QM-audits), it can be assumed that the integrated FPC-relevant part is well covered. On this basis, the work of the manufacturer is well controlled, so that the frequency of special FPC-surveillance-assessments can be reduced.
Page 15 prEN 12259-12:2004
7.3.5.3 Any assessment and its results shall be documented in a report. 7.3.6
Procedure for modifications
In the case of modification of the component, the method of production or the FPC system (where these may affect the stated properties), a re-assessment of the factory and of the FPC system shall be performed for those aspects which may be affected by the modification. Any assessment and its results shall be documented in a report.
