MEASUREMENT METHODS AND CALCULATIONS  
 
1. For the purposes of compliance and verification of compliance  with the requirements 
of this Communique, measurements and calculations shall be made using harmonised standards 
the reference numbers of which have been published for this purpose in the Official Journal of 
the European Union, or other reliable, accurate  and reproducible methods, which take into 
account the generally recognised state -of-the-art, and in line with the following provisions:  
 
2. FOR MOTORS  
 
a) The difference between the output mechanical power and the input electrical power is 
due to losses o ccurring in the motor.  
 
b) Total losses shall be determined using the following methods, based on a 25 °C 
reference ambient temperature: : 
 
- Single -phase motors: Direct measurement: Input -Output;  
 
- Three -phase motors: Summation of losses: Residual losses.  
 
c) However, for the seven operating points according to Annex I. Part 2 (3)(a), the losses 
shall be determined by either direct input -output measurement or by calculation . 
 
3. FOR VARIABLE SPEED DRIVES  
 
a) For the determination of the IE class, the power  losses of VSDs shall be determined at 
100 % rated torque -producing current and 90 % rated motor stator frequency. .   
            
 b) The losses shall be determined according to one of the following methods:  
 
 - the input -output method; or  
 
 - the calorimetric method.  
 
 c) The test switching frequency shall be 4 kHz until 111 kVA (90 kW) and 2 kHz above, 
or at the default factory settings as defined by the manufacturer.  
 
 ç) It is acceptable to measure VSD losses at a frequency of up to 12 Hz instea d of zero.  
 
 d) Manufacturers or their authorised representatives can also use the single loss 
determination method. Calculations have to be performed with respect to component 
manufacturer’s data with typical values of power semiconductors at the actual V SD operating 
temperature or at the maximum operating temperature specified in the datasheet. When no 
component manufacturer data is available, losses shall be determined by measurement. 
Combination of calculated and measured losses are allowed. The differe nt individual losses are 
calculated or measured separately and the total losses are determined as the sum of all individual 
losses.   
 
 
ANNEX -III 
 
VERIFICATION PROCEDURE FOR MARKET SURVEILLANCE PURPOSES  
 
 1. The verification tolerances defined in this Annex relate only to the verification by the 
Ministry  of the declared values and shall not be used by the manufacturer, importer or 
authorised representative as an allowed tolerance to establish the values in the technical 
documentation or in interpreting these values with a view to achieving compliance or t o 
communicate better performance by any means . 
 
2. Where a model has been designed to be able to detect it is being tested (e.g. by 
recognising the test conditions or test cycle), and to react specifically by automatically altering 
its performance during the test with the objective of reaching a more favou rable level for any 
of the parameters specified in this Communique  or included in the technical documentation or 
included in any of the documentation provided, the model and all equivalent models shall be 
considered not compliant.  
 
3. As part of verifying that a product model complies with the requirements laid down in 
this Communique pursuant to Article 5(2) of the Regulation on Ecodesign Requirements for 
Energy -Related Products (2009/125/EC) of the Ministry shall apply the following procedure 
for the requ irements referred to in Annex I. : 
 
(a) the Ministry shall verify one single unit of the model; . 
 
(b) the model shall be considered to comply with the applicable requirements if:  
 
1) the values given in the technical documentation pursuant to Article 2 of A nnex IV of 
the Regulation on Ecodesign Requirements for Energy -Related Products (2009/125/EC) 
(declared values), and, where applicable, the values used to calculate these values, are not more 
favourable for the manufacturer, importer or authorised represen tative than the results of the 
corresponding measurements carried out pursuant to paragraph (f) thereof; and  
 
2) the declared values meet any requirements laid down in this Communique and any 
required product information published by the manufacturer, importer or authorised 
representative does not contain values that are more favourable for the manufacturer, importer 
or authorised representative than the declared values; and  
 
3) when the Ministry tests the unit of the model, the determined values (the v alues of the 
relevant parameters as measured in testing and the values calculated from these measurements) 
comply with the respective verification tolerances as set out in Table 7.  
 
(c) If the results referred to in points (b)(1) or (b)(2) are not achieved  the model and all 
equivalent models shall be considered not to comply with this Comminique . 
 
 (ç) If the result referred to in point (b)(3) is not achieved;  
  1) for models that are produced in quantities of less than five per year including equivalent 
models, the model and all equivalent models shall be considered not to comply with this 
Communique;  
 2) for models that are produced in quantities of five or more per year including equivalent 
models, the Ministry shall select three additional units of the  same model for testing. As an 
alternative, the three additional units selected may be one or more of equivalent models.  
  
 (d) 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 7.  
 
 (e) If the result referred to in point (d) is not achieved the model and all equivalent models 
shall be considered not to comply with this Communique . 
  
 (f) The Min istry 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 (c), (e) or the second paragraph of this Anne x. 
 
 4. The Ministry shall use the measurement and calculation methods set out in Annex II.  
 
 5. Given the weight and size limitations for the transportation of motors with a rated 
power output of 375 to 1 000 kW the Ministry may decide to undertake the verification 
procedure at the premises of manufacturers, authorised representatives or importers before the 
products are put into service. The Ministry can do this verification using its own testing 
equipment.  
 
 6. If factory acceptance tests are planned f or such motors, which will test parameters laid 
down in Annex I of this Communique, the Ministry may decide to use witnessed testing during 
these factory acceptance tests to gather test results which can be used to verify compliance of 
the motor under inve stigation. The authorities may request a manufacturer, authorised 
representative or importer to disclose information on any planned factory acceptance tests 
relevant for witnessed testing.  
 
 7. In the cases mentioned in the two paragraphs above, the Minist ry only needs to verify 
one single unit of the model. If the result referred to in point 3(b)(3) is not achieved, the model 
and all equivalent models shall be considered not to comply with this Communique.  
 
 8. The Ministry shall only apply the tolerances set out in Table 7 and shall only use the 
procedure described in point 3  for the requirements referred to in this Annex. For the parameters 
in Table 7, no other tolerances such as those set out in harmonised standards or in any other 
measurement method sha ll be applied.

BENCHMARKS  
 
 
1.  At the time of adoption of this Communique the best available technology on the 
market for the environmental aspects that were considered significant and are quantifiable is 
indicated below. . 
 
a)  For motors the IE4 level was identified as the best available technology. Motors with 
losses that are 20 % lower exist but within limited availability and not in all power ranges 
covered by this Communique and not in the form of induction motors.  
 
b) For variable speed drives, the best available technology on the market corresponds to 
20 % of the reference power losses referred to in Table 6. By utilising silicon carbide 
technologies (SiC MOFSET), semiconductor losses could be further reduced by about 50 % 
compared to a conventional solution.
