3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 1 070 and EN 1 028-1 apply. 4 Verifications 4.1 General 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 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 manufacturer 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 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 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 installation 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 testing. NOTE 1 If 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 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 clauses 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. EN 1028-2  pdf download.
