EN 1028-2:2002 (E) 3 Foreword This document EN 1028-2:2002 has been prepared by Technical Committee CEN/TC 192 “Fire service equipment“, the secretariat of which is held by BSI. This European Standard shall be given the status of a nati
18、onal standard, either by publication of an identical text or by endorsement, at the latest by January 2003, and conflicting national standards shall be withdrawn at the latest by January 2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Fr
19、ee Trade Association, and supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative annex ZA, which is an integral part of this document. This part of this European Standard shall be applied only in conjunction with EN 1028-1 “Classification - General
20、 and safety requirements“. This part of this European Standard includes the verification of general and safety requirements of fire- fighting centrifugal pumps with primer. EN 1028 “Fire-fighting pumps Fire-fighting centrifugal pumps with primer“ comprises two parts: Part 1: Classification - General
21、 and safety requirements; Part 2: Verification of general and safety requirements. The annexes A to J are normative. The annex K is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Sta

EN 1028-2:2002 (E) 4 0 Introduction This European Standard is a type C standard as state
23、d in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. Where provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C s
24、tandard take precedence over the provisions of the other standards, for machines that have been designed and built in accordance with the provisions of this type C standard. This Standard has been prepared as a harmonized standard to provide one means of conformity with essential requirements of the
25、 Machinery Directive and associated EFTA Regulations. 1 Scope This European Standard covers verification of the general and safety requirements of fire-fighting centrifugal pumps with primer as specified in clauses 7 and 8 of EN 1028-1:2002. NOTEThe tests can also be applied to pumps with nominal de
26、livery rates greater than 6 000 l/min. This standard does not apply to verification related to installation. This standard does not apply to fire-fighting centrifugal pumps with primer that are manufactured before the date of publication by CEN of this standard. 2 Normative references This European
27、Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications app
28、ly to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

EN 1028-2:2002 (E) 5 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 1070 and EN 1028-1 apply. 4 Verifications 4.1Gene
31、ral Safety and performance requirements of clauses 5 and 6 of EN 1028-1:2002 shall be verified according to Tables 2 and 3. All hydraulic tests shall be carried out using water having a temperature between 0 C and 20 C. During one test cycle, the water temperature shall not deviate by more than 3 C
32、within this temperature range. The geodetic suction height shall not deviate by more than 5 cm during one test cycle. In order to avoid air entrainment, the test configuration shall be as shown in Figure A.1 in annex A. If the safety equipment has to be disconnected to carry out any test, the manufa
33、cturer shall give information regarding the disconnected safety equipment (e.g. compensating or alternative safety measures to be used during the test and re-connection instructions after completing the test). Verification shall be carried out with the pump equipment assembled for normal intended us
34、e. Accessories and covers may be fitted or not, but the effect in either case shall not obscure the validity of the test. Where the pump is assembled on site, the part of the verifications that cannot be made before dispatch shall be carried out at the place of use in accordance with the installatio
35、n instructions of the pump manufacturer. For testing purposes, the fire-fighting centrifugal pump shall be presented in its full operational configuration. The pump shall be equipped to undergo the full range of tests required. For pumps without a driving motor, a drive flange shall be provided for
36、testing. NOTE 1If dimensions, mass, or other factors make particular tests on complete equipment impractical, tests can be carried out on subassemblies or components provided that the results can be verified as representative of the fully assembled equipment. NOTE 2A guidance for acceptance tests on
37、 delivery is given in the informative annex K. The verification regime covers the following basic verifications which applies in clauses 5 and 6. 4.2 Type verification Ensure that each type of the pump meets the requirements of this standard. NOTEThis verification is indicated as “TYP“ in Tables 2 a
38、nd 3. 4.3Individual verification Ensure that each pump put on the market meets the requirements of this standard before dispatch. NOTEThis verification is indicated as “IND“ in Tables 2 and 3. ? EN 1028-2:2002 (E) 6 4.4Methods of verification The methods of type and/or individual verifications are d
39、escribed as follow. 4.4.1 Calculation check Determine that the calculations are correct according to the standard requirements. Calculations used to establish compliance with a requirement shall be recorded by the manufacturer and retained for future examination. NOTEThe calculation check can be rep
40、laced by a stress measurement test if the results are equivalent. 4.4.2 Design check Determine that the design requirements of the standard have been achieved (design documentation). 4.4.3 Compliance verification (manufacturing check) Determine that the pump is built according to the design and that
41、 the materials and their assemblies comply with the design documents and are sound, including the following. 4.4.3.1 Verification of documents Determine that all necessary documents are present (e.g. attestations of conformity of supplied parts by the supplier). 4.4.3.2 Visual check Determine by sim
42、ple visual inspection that something is present (e.g. guard, marking, document), that the marking contains the required information/warnings, that there is no evident external leakage etc. ? EN 1028-2:2002 (E) 7 4.4.3.3 Verification by measurement (see also annexes C, D, E, H, I and J.4) Determine b
43、y measurement, with suitable measuring instruments, that the requirements of the measurable parameters of the standard have been met (e.g. geometric dimensions, delivery rate, pressure, temperatures) (see also 4.5). Methods of measurement should be selected to make use of existing or standardised me
44、thods. 4.4.3.4 Static test (see also annex G) Test out of the range of functional tests. Conduct the static pressure test and establish that the pump complies with the requirements of the standard. 4.4.3.5 Dynamic test (see also annex G) Test out of the range of functional tests. Conduct the dynamic
45、 test and establish that the pump complies with the requirements of the standard. Check that all safety devices are installed correctly and that their operation is as intended. 4.4.3.6 Functional tests (see also annexes D, E, F, G, I, J) Determine by functional tests that the pump operates to the re
46、quirements of the standard including all safety devices, except those related to pressure overload protection. 4.4.3.7 Test of pressure overload protection devices (see also annexes E, G) Determine that any pressure overload protection device operates to the requirements of the standard. 4.4.3.8 Ver
47、ification of the information for the user Verify that all necessary information for safe commissioning, use, maintenance/inspection, decommissioning etc. as stated in the standard are present and adequate. 4.4.3.9 Verification of the information for the installer Verify that all necessary informatio
48、n on installation are present and adequate. 4.5Measuring instruments Measuring instruments for the measurements specified in annexes B, C, D, E, F, G, H, I and J shall have an accuracy conforming to Table 1. ?
