ANNEX III

Measurements and calculations

For the purposes of compliance and verification of compliance with the requirements of this Regulation, measurements and calculations shall be made using harmonised standards the reference numbers of which have been published in the Official Journal of European Union, or using other reliable, accurate and reproducible methods, which take into account the generally recognised state of the art, and produce results deemed to be of low uncertainty. They shall fulfil all of the following technical parameters.

The hydraulic pump efficiency, as defined in Annex I, is measured at the head and flow corresponding to the best efficiency point (BEP), part load (PL) and over load (OL) for full impeller diameter with clean cold water.

The formula for calculating the required minimum efficiency at best efficiency point (BEP) is as follows:

Where,

x = ln (ns); y = ln (Q) and ln = natural logarithm and Q = flow in [m3/h]; ns = specific speed in [min–1]; C = value found in Table.

The value of C depends on the pump type and nominal speed, and also the MEI value.







Table Minimum efficiency index (MEI) and its corresponding C-value depending on the pump type and speed C-value for MEI CPumpType,rpm MEI = 0,10 MEI = 0,40 C (ESOB, 1 450 ) 132,58 128,07 C (ESOB, 2 900 ) 135,60 130,27 C (ESCC, 1 450 ) 132,74 128,46 C (ESCC, 2 900 ) 135,93 130,77 C (ESCCi, 1 450 ) 136,67 132,30 C (ESCCi, 2 900 ) 139,45 133,69 C (MS-V, 2 900 ) 138,19 133,95 C (MSS, 2 900 ) 134,31 128,79

The requirements for part load (PL) and over load (OL) conditions are set at slightly lower values than those for 100 % flow (ηΒΕΡ).

All efficiencies are based on full (untrimmed) impeller. Vertical multistage water pumps are to be tested with a 3 stage (i = 3) version. Submersible multistage water pumps are to be tested with a 9 stage (i = 9) version. If this number of stages is not offered within the specific product range the next higher number of stages within the product range is to be chosen for testing.

ANNEX IV

Product compliance verification by market surveillance authorities

The verification tolerances defined in this Annex relate only to the verification of the measured parameters by Member State authorities and shall not be used by the manufacturer or importer as an allowed tolerance to establish the values in the technical documentation or in interpreting these values with a view to achieving compliance or to communicate better performance by any means.

When verifying the compliance of a product model with the requirements laid down in Annex II to this Regulation pursuant to Article 3(2) of Directive 2009/125/EC, for the requirements referred to in this Annex, the authorities of the Member States shall apply the following procedure:

(1) The Member State authorities shall verify one single unit of the model.

(2) The model shall be considered to comply with the applicable requirements if:

(a) the values given in the technical documentation pursuant to point 2 of Annex IV to Directive 2009/125/EC (declared values), and, where applicable, the values used to calculate these values, are not more favourable for the manufacturer or importer than the results of the corresponding measurements carried out pursuant to paragraph (g) thereof; and

(b) the declared values meet any requirements laid down in this Regulation, and any required product information published by the manufacturer or importer does not contain values that are more favourable for the manufacturer or importer than the declared values; and

(c) when the Member State authorities test the unit of the model, the determined values (the values of the relevant parameters as measured in testing and the values calculated from these measurements) comply with the respective verification tolerances given in Table 2.

(3) If the results referred to in point 2(a) or (b) are not achieved, the model shall be considered not to comply with this Regulation.

(4) If the result referred to in point 2(c) is not achieved, the Member State authorities shall select three additional units of the same model for testing.

(5) The model shall be considered to comply with the applicable requirements if, for these three units, the arithmetical mean of the determined values complies with the respective verification tolerances given in Table 2.

(6) If the result referred to in point 5 is not achieved, the model shall be considered not to comply with this Regulation.

(7) The Member State authorities shall provide all relevant information to the authorities of the other Member States and to the Commission without delay after a decision being taken on the non-compliance of the model according to points 3 and 6.
