The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. 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 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.

EN 14710-2:2005+A2:2008 (E) 6 1 Scope This document covers verification of the general and safety requirements of fire-fighting centrifugal pumps without primer as specified in #EN 14710-1$. #NOTE The tests can also be applied to pumps with nominal delivery rates greater than 10 000 l/min.$ This document does not apply to fire-fighting centrifugal pumps without primer that are manufactured before the date of publication by CEN of this document. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. #EN 1028-1$, Fire-fighting pumps — Fire-fighting centrifugal pumps with primer — Part 1: Classification — General and safety requirements #EN 1028-2$, Fire-fighting pumps — Fire-fighting centrifugal pumps with primer — Part 2: Verification of general and safety requirements #EN 14710-1:2005$, Fire-fighting pumps — Fire-fighting centrifugal pumps without primer — Part 1: Classification, general and safety requirements EN ISO 12100-1:2003, Safety of machinery - Basic concepts, general principles for design - Part 1: Basic terminology, methodology (ISO 12100-1:2003) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and #EN 14710-1:2005$ apply. 4 Verification, Principles 4.1 General The verification in accordance with this part of this document is limited to the pump and not including installation. Safety requirements of #EN 14710-1:2005$, Clause 5 shall be verified according to Table 2. Performance requirements of #EN 14710-1:2005$, Clause 6 shall be verified according to Table 3. All hydraulic tests shall be carried out using water having a temperature between 15 °C and 25 °C. The geodetic inlet height shall not deviate by more than ± 5 cm during one test cycle. In order to avoid air entrainment, the test configurations shall be as shown in Figure A.1 to Figure A.4. 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). SIST EN 14710-2:2005+A2:2009
EN 14710-2:2005+A2:2008 (E) 7 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. NOTE 1 For pumps without a driving motor, a driving flange should be provided for testing. For pumps without a driving flange a driving system should be supplied. NOTE 2 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 3 A guidance for acceptance tests on delivery is given in the informative Annex H. The verification regime covers the following basic verifications which apply in Clauses 5 and 6. For pumps according to # EN 1028-1 and EN 1028-2$ used as a pump without primer according to this document, e.g. as a "Boosted pump" by disusing the priming device, with the same classification (e.g., FPN 10-1000 used as FPN-B 10-1000), no tests according to this document are required. For pumps according to the series of European Standards EN 1028 used as a pump without primer according to this document, e.g. as a "Boosted pump" by disusing the priming device, with a higher classification (e.g., FPN 10-1000 used as FPN-B 10-1500), the tests according to this document shall be carried out. 4.2 Type verification Ensure that each type of the pump meets the requirements of this document. 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 document before dispatch. NOTE This verification is indicated as "IND" in Tables 2 and 3. 4.4 Methods of type and/or individual verification 4.4.1 Calculation check, stress measurement test Determine that the calculations are correct according to the standard requirements. Calculations and stress measurement test results used to establish compliance with a requirement shall be recorded by the manufacturer and retained for future examination. The calculation check can be replaced 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).

Methods of measurement should be selected to make use of existing or standardised methods. 4.4.3.5 Static test (in accordance with Annex F) 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. 4.4.3.6 Dynamic test (in accordance with Annex F) Test out of the range of functional tests. Conduct the dynamic test and establish that the pump complies with the requirements of the standard.
