1、 y!“ # # $ %23%*8* 444342 “% % it has been determined that the standard complies with the requirements of 2006/42/EC. Therefore, CEN/TC 192 decided in June 2007 to use the “simple amendment” (type 1) procedure which does not involve any technical modifications, but only a few minor editorial changes
2、 (e.g. updating the Foreword) and the addition of a new Annex ZB. Amendment A1:2008 thus concretizes in conjunction with EN 1028-2:2002 the basic requirements set out in Annex I of the EU Machinery Directive 98/37/EC (valid until 28 December 2009) and the new Machinery Directive 2006/42/EC which bec
3、omes applicable on 29 December 2009 relating to machines to be placed on the EEA market, with the intent of simplifying the means of proving conformity with such. Once this standard is designated a harmonized standard in the Official Journal of the European Union, a manufacturer applying this new co
4、nsolidated version of the standard may assume compliance with the requirements of the Machinery Directive (the so-called “presumption of conformity”). A revision of Part 1 of EN 1028 (EN 1028-1:2002) was also necessary for the same reasons. This European Standard is to be applied in conjunction with
5、 Part 1 of EN 1028 Classification General and safety requirements. The 2002 edition of this European Standard, together with EN 1028-1, replaced the German standards specifying requirements for and the testing of pumps for fire-brigades, DIN 14420-1:1986-02 and DIN 14420-2:1989-04. Because these two
6、 national standards had to be withdrawn upon the publication of the European Standards, a “residual standard” was published as DIN 14420 containing national provisions not covered by the European Standard but which are necessary for the application of DIN EN 1028 in Germany. The DIN collective mark
7、may be applied to pumps complying with this standard if they have been registered by DIN CERTCO.

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
29、 are different from those which are stated in type A or B standards, the provisions of this type C standard 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 pre
30、pared as a harmonized standard to provide one means of conformity with essential requirements of the 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 specif
31、ied in clauses 7 and 8 of !EN 1028-1:2002+A1:2008“. NOTE The tests can also be applied to pumps with nominal delivery 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
32、 are manufactured before the date of publication by CEN of this standard. 2 Normative references This European 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
33、 listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply 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).

36、 definitions For the purposes of this European Standard, the terms and definitions given in EN 1070 and !EN 1028-1:2002+A1“ apply. 4 Verifications 4.1 General Safety and performance requirements of clauses 5 and 6 of !EN 1028-1:2002+A1:2008“ shall be verified according to Tables 2 and 3. All hydraul
37、ic 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 within this temperature range. The geodetic suction height shall not deviate by more than 5 cm during one test cycle. In order to avoid
38、 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 manufacturer shall give information regarding the disconnected safety equipment (e.g. compensating or alternative safety measures to be used
39、during the test and re-connection instructions after completing the test). Verification shall be carried out with the pump equipment assembled for normal intended use. Accessories and covers may be fitted or not, but the effect in either case shall not obscure the validity of the test. Where the pum
40、p 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 installation instructions of the pump manufacturer. For testing purposes, the fire-fighting centrifugal pump shall be presented in its full operat
41、ional 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 testing. NOTE 1 If dimensions, mass, or other factors make particular tests on complete equipment impractical, tests can be carried out
42、 on subassemblies or components provided that the results can be verified as representative of the fully assembled equipment. NOTE 2 A guidance for acceptance tests on delivery is given in the informative annex K. The verification regime covers the following basic verifications which applies in clau
43、ses 5 and 6. 4.2 Type verification Ensure that each type of the pump meets the requirements of this standard. NOTE This verification is indicated as “TYP“ in Tables 2 and 3. 4.3 Individual verification Ensure that each pump put on the market meets the requirements of this standard before dispatch. NOTE This verification is indicated as “IND“ in Tables 2 and 3. 5 DINEN10282:200806
