3. 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 for this purpose in the 
Offici al Journal of the European Union , or other reliable, accurate and r eproducible 
methods, which take  into account the generally recognised state  of the art.  
EN 4  EN ANNEX II 
Verification procedure  for market surveillance purposes  
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 esta blish 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 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 documentati on 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 de termined 
values (the values of the relevant parameters as measured in testing and the 
values calculated from these measurements) comply with the respective 
verification tolerances as given in the table  on verification tolerances . 
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 testin g. 
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 the table on verification tolerances . 
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 withou t delay after a decision is 
taken on non -compliance of the model according to points  3 and  6. 
The Member State authorities shall use the measurement and calculation methods  set out in 
Annex  I.  
The Member State authorities shall only apply the verification tolerances that are set out in the 
table on verification tolerances  and shall only use th e procedure described in points  1 to 7 for 
the requirements referred to in this Annex. No other toleranc es, such as those set out in 
harmonised standards or in any other measurement method, shall be applied.

No-load condition  The determined value shall not exceed the 
declared value by more than 0,01 W. 
Arithmetical mean of efficiency at 
load conditions 1 -4 as defined in 
Annex  I The determined value shall not be lower 
than th e declared value by more than 5  %.  
EN 6  EN ANNEX III 
Benchmarks  
The best available technology on the market, at the time of entry into force of this Regulation, 
for the environmental aspects that were considered significant and are quantifiable is 
indicated below.  
At the time of entry into force of this Regulation, the best available technology on the market 
for external power supplies  in terms of  their no-load energy consumption and average active 
efficiency  was identified as follows.  
(a) No-load condition  
The lowest available no -load condition energy consumption of external power supplies can be 
approximated as: 
– 0,002 watt, for P O ≤ 49,0 watts; 
– 0,010 watt, for P O > 49,0 watts. 
(b) Average active efficiency  
The best available active average efficiency of external power supplies according to most 
recent available data (status March  2015 ) can be approximated as:  
– 0,767, fo r PO ≤ 1,0 watt; 
– 0,905, for  1,0 watt < PO ≤ 49,0 watts; 
– 0,962, for P O > 49,0 watts.
