EN 1  EN ANNEX I  
Definitions applicable for Annexes I to V  
For the purpose of the Annexes , the following definitions shall apply:  
(1) ‘power source efficiency’ means the ratio, expressed in a percentage, of the welding 
output power at conventional welding conditions and conventional welding load 
voltages , to the highest power consumption of the supply source ;  
(2) ‘idle state’ means the operating state in  which the power is switched on and the 
welding circuit is not energised ;  
(3) ‘'Idle state power consumption ’ means  the power demand, in Watts , in idle state ;  
(4) ‘highest power consumption ’ means  the maximum power consumption required by a 
welding process, excluding the power draw from any other device , including  any 
power suppl y, connected to the welded piece ; 
(5) ‘cold state’ means the state of the power source after a cool -down period, at which the 
temperature is constant, any fans or cooling pumps present have stopped, and the 
power source has switched into a low energy idle state ; 
(6) ‘power source’ means a device that utilises alternating current (AC) to either power one 
or more AC power outputs, or  which converts AC or direct current (DC) input power 
to one or more DC power outputs, for the purpose of powering a welding equipment 
product ; 
(7) ‘component ’ means a part which normally cannot be taken apart without destruction or 
impairment of the use of th e component in the overall product , unless readily and 
economically separable into principal sub -components which may be rapidly 
disassembled and replaced ;  
(8) ‘control panel’ means  an overall operating interface containing the controls and 
indicators of elec trical, electronic, materials use and measurable emissions parameters 
between the user of the product and the electronic and electro -mechanical components, 
inputs and outputs ; 
(9) ‘equipment housing’ means  a protective casing of the product, often constructed from 
metal and plastics, giving robust protection to the product from the atmosphere, 
humidity and possible shock impacts, but which must also be able to readily 
disassembled in order to give access to the components ; 
(10) ‘battery’ means a device as defined in  Article 3 of Directive 2006/66/EC, in the sense 
also of 'battery pack' or 'industrial battery or accumulator' in the same Artic le;   
(11) ‘welding torch’ means  a device which delivers the welding current to the electrode, 
which may include transferring the current to a consumable electrode, where used, and 
which also delivers the shielding gas, where used, to the electric arc area ;  
(12) ‘gas supply hose’ means  a supply hose specifically designed for fuel supply of gases 
(such as  acetylene), compressed air and sh ielding gases used in welding, normally 
consisting of a tube and a protective cover, often specific to the gas type used, and 
sometimes to the operating conditions ;    
(13) ‘gas supply regulator’ means  a device which reduces the higher pressure of the 
supplied compressed gases to the lower pressure that can be safely used  in the welding 
equipment, often equipped with a metering valve or flowmeter to measure and/ or 
control gas flow ;  
EN 2  EN (14) ‘welding wire drive’ means  a device , used to  feed welding wire or filler materia l, that 
may be of the type of  push, pull or a push -pull combination ; 
(15) ‘fan’ means a rotary bladed machine used to maintain a continuous flow of gas, 
typically air, passing through it and acts for instance as the  internal cooling system for 
the power source ; 
(16) ‘electricity supply cable’ means  a welding supply cable meeting the requirements of 
recognised welding cable standards, including insulation performance, specific to the 
particular needs of the application, as needed ( such as special requirements related to 
plasma cutting, where applicable) and capable of providing electricity of sufficient 
performance and safety characteristics .

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 Official Journal of the 
European Union , or using other reliable, accurate and reproducible methods which take into

uncertainty .  
EN 8  EN ANNEX IV 
Verification procedure  for market surveillance purposes  
The verification tolerances defined in this Annex relate only to the ve rification 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 's model with the requirements laid down in th e 
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 unit of the model or model 
configuration.  
2. The model or model configuration shall be considered to comply with the applicabl e 
requirements where the following conditions are met: 
(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;  
(b) the declared values meet any requirements laid down in th e 
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;  
(c) when the Member State authorities test the unit of the model or 
model configuration, the determined values (the values of the 
relevant parameters as measured in te sting and the values 
calculated from these measurements) comply with the functional 
requirements and the requirements on repair and end -of-life aspects 
and the verification tolerances as given in Table 3. 
3. Where  the results referred to in points 2(a) or 2(b) are not achieved, the model and all 
model configurations that are covered by the same product information shall be 
considered not to comply with th e Regulation.  
4. Where  the result referred to in point 2(c) is not achieved, the Member State 
authoritie s shall select three additional units of the same model or model 
configuration for testing.  
5. The model or model configuration shall be considered to comply with the applicable 
requirements if, for these three units, the arithmetical mean of the determin ed values 
complies with the respective verification tolerances given in Table 3. 
6. Where  the result referred to in point 4 is not achieved, the model and all model 
configurations that are covered by the same product information shall be considered 
not to comply with th e Regulation.   
EN 9  EN 7. The Member State authorities shall provide all relevant information to the authorities 
of the other Member States and to the Commission immediately  after a decision 
being taken on the 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 III. 
The Member State authorities shall only apply the verification tolerances that are set out in 
Table 3 and shall only use the procedure desc ribed in points 1 to 7 for the requirements 
referred to in this Annex. No other tolerances shall be applied.
