Verification procedure for the purpose of market surveillance  referred to in Article 4 
The verification tolerances defined in this Annex relate only to the verification of the declared 
parameters by Member State authorities and shall not be used by the man ufacturer, importer 
or authorised representatives 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.  
Where a  model is not in conformity with the requirements laid down in Article 6, the model 
and all equivalent models shall be considered not compliant.  
As part of verifying the compliance of a local space heater model with the requirements laid 
down in this Regulation pursuant to Article 3(2) of Directive 2009/125/EC, the authorities of 
the Member States shall apply the following procedure:  
(1) the Member State authorities shall verify  one sin gle unit per model;  
(2) the model  and all equivalent models  shall be consid ered to comply with the 
requirements set out in this Regulation if all the following conditions are fulfilled : 
(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, importer or authorised representative than the results of the 
corresponding measurements referred to in that point under  (g);  
(b) the declared values meet any requireme nts laid down in this Regulation, and 
any required product information published by the manufacturer, importer or 
authorised representative does not contain values that are more favourable for 
the manufacturer or importer than the declared values;  
(c) when th e Member State authorities check the unit of the model , they find that 
the manufacturer, importer or authorised representative has put in place a 
system that complies with the requirements in Article 7;  
(d) when the Member State authorities check the unit of the model, it complies 
with the product information requirements in point 4 and resource efficiency 
requirements in point 5 of Annex II;  
(e) when the Member State authorities test the unit of the model  and the 
determined values (the values of the relevant par ameters as measured in testing 
and the values calculated from these measurements), achieved through a valid 
test, comply with the following:  
(i) for electric local space heaters , the seasonal space heating energy 
efficiency ηs is not  worse than  the declared value at th e nominal heat 
output of the unit;  
(ii) for liquid fuel local space heaters , the seasonal space heating energy 
efficiency ηs is not more than 8% lower tha n the declared value;  
(iii) for gaseous fuel local space heaters , the seasona l space heating energy 
efficiency ηs is not more than 8% lower tha n the declared value;  
(iv) for gaseous and liquid fuel local space heaters the emissions of NO x are 
not more than 10%  higher tha n the declared value;  EN 32  EN (v) for commercial  local space heaters t he seasonal space heating energy 
efficiency  is not more tha n 10% lower  than the declared value ; 
(vi) for commercial  local space heaters the emissions of NO x are not more 
than 10% higher tha n the declared value ; 
(3) if the conditions  referred to in point (2)(a), (b) (c) or (d) are not fulfilled , the Member 
State authorities shall declare the model concerned and all equivalent models not to 
comply with this Regulation ; 
(4) if the result referred to in point 2(e) is not achieved, or if the test is not valid because 
the unit tested in compliance with the test conditions according to the relevant 
harmonised standards does not meet the requirements for a test to be valid as 
required by the relevant harmonised standards, the Member State authori ties shall 
select three additional units of the same model for testing. As an alternative, the three 
additional units selected may be of one or more equivalent models ;  
(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 values given in point 2(e) ; 
(6) if the result referred to in point (5) is not achieved, the model and all equivalent 
models shall be considered not to comply with this Reg ulation. This includes 
situations for which one of the three units tested in compliance with the test 
conditions according to the relevant harmonised standards does not meet the 
requirements for a test to be valid as required by the relevant harmonised sta ndards ; 
(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 in accord ance with  points (3) or ( 6); 
(8) the Member State authorities shall use the measurement and calculati on methods set 
out in Annex III;  
(9) the Member State authorities shall only apply the tolerances that are set out in point 
2(e) and shall use only the procedure described in points (1) to  (8) for the 
requirements referred to in this Annex. No other tolerances, such as those set out in 
harmonised standards or in any other measurement method, shall be applied.  EN 33  EN ANNEX V I 
Indicative benchmarks referred to in Article 6  
At the t ime of entry into force of this Regulation, the best available technology on the market 
for local space heaters  in terms of seasonal space heating energy efficiency and emissions of 
nitrogen oxides  was identified as follows:  
(1) specific benchmarks  for seasonal space heating energy efficiency  of local space 
heaters : 
(a) open fronted local  space heaters: 65%;  
(b) open combustion  closed fronted local space heaters and balanced flue local 
space heaters : 88%;  
(c) electric local space heaters: more than 51%; 
(d) luminou s local space heaters: 92%;  
(e) tube local space heaters: 88%;  
(2) Specific benchmarks for emissions of nitrogen oxides (NO x) by local space heaters : 
(a) local space heaters using gaseous or liquid fuel : 50 mg/kWh input based on GCV ; 
(b) luminous  local space heaters and tube local space heaters : 50 mg/kWh input 
based on GCV . 
The be nchmarks specified in the points 1 and 2 do not necessarily imply that a combination of 
those values is achievable for a si ngle local space heater.
