20、, Sun Jul 30 11:11:33 BST 2006, Uncontrolled Copy, (c) BSI ? EN 14343:2005 (E) 4 1 Scope This European Standard describes specified types of acceptance tests for rotary positive displacement pumps for applications other than fluid power, excluding progressing cavity and peristaltic type pumps. This
21、European Standard applies to the testing of pumps with and without drivers. This European Standard covers a selection of tests to establish a uniform demonstration of the pumps ability to perform satisfactorily. It does not, however, cover all tests that may be needed for particular pump types or ap
22、plications, e.g. tests for hazardous liquids or single shaft multiple pump units. Furthermore, it does not cover any noise and vibration tests, priming tests nor any hydrostatic pressure tests. Some pump types with integral relief valves may require more extensive relief valve tests than described i
23、n this European Standard. For dosing and metering applications, further tests to demonstrate the dosing and metering abilities of the pumps may be necessary. NOTE Extrapolation of test results to non-tested pumps is not described in this European Standard. Such extrapolation could be made for mass-p
24、roduced pumps with reference to pertinent quality assurance methods and standards. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest editi
25、on of the referenced document (including any amendments) applies.

EN 14343:2005 (E) 5 3.2.3 T3 inlet pressure test test to verify that the pump operates satisfactorily without cavitation at specified inlet pressure conditions NOTE The inlet pressure test T3 is not designed to establish the limit for cavitation, nor is it intended
29、 to establish the priming characteristics of the pump. Some guidance for priming tests is given in Annex B. Such a test, when required, may be made part of the test programme, but will require separate description of the test procedure and acceptance criteria, adapted to the subject type of pump. 3.
30、2.4 T4 relief valve test test to verify the pressure accumulation of a relief valve and its ability to reseat/close when the pressure is returned to normal 3.3 Test levels 3.3.1 L1 works test manufacturers internal quality assurance test. This test level is a pass/fail test without any formal record
31、ing requirements 3.3.2 L2 standard test manufacturers internal quality assurance test, with traceable records of pertinent test data 3.3.3 L3 order specified test test to verify the performance of a pump or pump unit at specified conditions. Test data are recorded 3.3.4 L4 observed test test to veri
32、fy the pump or pump unit performance at specified conditions. The purchaser is given an opportunity to have a representative present at test. Test data are recorded 3.3.5 L5 witness test test to verify the pump or pump unit performance at specified conditions. The purchaser needs a representative pr
33、esent at test (shall be a hold point). Test data are recorded 3.4 Other terms 3.4.1 test condition variables (TCV) those variables, such as pressure, speed and viscosity, that are directly controlled by the test arrangement and its operation 3.4.2 test result variables (TRV) those variables, such as
34、 flow and power consumption, that are obtained as a result of TCV and reflect the performance of the object under test 3.4.3 accuracy grade set of instrumentation and test equipment accuracy requirements 3.4.4 tolerance class set of tolerance requirements for TRV 3.4.5 pressure accumulation for the
35、purpose of this European Standard, pressure accumulation is considered as the difference between the maximum pressure observed during relief valve opening and the specified operating pressure. This value includes the margin between operating pressure and valve setting and the pressure increase by re

EN 14343:2005 (E) 6 4 Performance requirements The supplier shall identify and specify in writing, prior to the test, the TCV values (test co
37、nditions) together with the corresponding requirement values of TRV (performance results) for each set. He shall also specify test level, accuracy grade and tolerance class relevant to the purpose of the test. NOTE For test levels L3, L4 and L5 the TCV (test condition variables) values should be sel
38、ected to conform as far as practical to the conditions of the order and agreed upon by manufacturer and purchaser. Unless otherwise specified and agreed between purchaser and supplier, the following default values shall apply: test type: T1 Flow test and, for pumps with integral valve or a valve dir

The supplier sh
40、all also be responsible for ensuring compliance with all relevant safety regulations and standards, unless testing is performed at an independent laboratory or at site, when conformity to safety regulations shall be ensured by the party responsible for the test location. 5.2 Test location Unless oth
41、erwise specified, testing shall be carried out at the suppliers works. If so agreed between purchaser and supplier, the testing may be carried out either at an independent test facility or at site. 5.3 Test date The supplier shall determine the date of test. For observed or witness test (level L4 an
42、d L5), a minimum of 10 calendar days notice shall be provided to the purchaser unless otherwise agreed in advance. 5.4 Test programme The test procedure shall be described in a test programme prior to test. For observed test L4 or witness test L5, the test programme shall be made available to the pu
43、rchaser prior to test. The test programme shall include details on scheduling and responsibility for test, test methods and arrangements, performance requirements as per Clause 4 above, verification levels for inlet pressure tests T3, when applicable (see 9.4.2), sequence and timing of actions and o
44、bservations, recording of test data, methods for data corrections (see 7.1), presentation of results etc. Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Sun Jul 30 11:11:33 BST 2006, Uncontrolled Copy, (c) BSI ?
