THE EUROPEAN COMMISSION, 
Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive 2010/30/EU of the Eur opean Parliament and of the Council of 19 
May 2010 on the indication by labelling and standard product information of the consumption of energy and other resour ces by energy-related products
1, and in particular Article 10 thereof, 
Whereas: (1) Directive 2010/30/EU re quires the Commission to a dopt delegated acts for the 
labelling of energy-related products repr esenting significant potential for energy 
savings and presenting a wide  disparity in performance levels with equivalent 
functionality. 
(2) Provisions for the energy labelling of household tumble driers were established by 
Commission Directive 95/13/ EC of 23 May 1995 implementing Council Directive 
92/75/EEC with regard to energy labell ing of household electric tumble driers
2.  
(3) The energy used by househol d tumble driers accounts for a significant part of total 
household energy demand in the Union. In  addition to the energy efficiency 
improvements already achieved, the scope for further reducing the energy consumption of household tumble driers is substantial. 
(4) Commission Directive 95/13/ EC should be repealed and ne w provisions should be laid 
down by this Regulation in order to ensure  that the energy label provides dynamic 
incentives for suppliers to further improve the energy efficiency of household tumble driers and to accelerate market transforma tion towards energy-efficient technologies. 
(5) Household combined washer-driers are addressed in Commission Directive 96/60/EC 
of 19 September 1996 implementing Council Directive 92/75/EEC with regard to

EN 2   EN energy labelling of househol d combined washer-driers3. They have particular 
characteristics and should therefore be exem pted from the scope of this Regulation.  
(6) The information provided on the label s hould be obtained through reliable, accurate 
and reproducible measurement procedures which take into acc ount the recognised 
state-of-the-art measurement methods, including, where available, harmonised 
standards adopted by the European standa rdisation bodies, as lis ted in Annex I to 
Directive 98/34/EC of the European Parlia ment and of the Council of 22 June 1998 
laying down a procedure for the provision of information in the field of technical 
standards and regulations and of ru les on Information Society services4. 
(7) This Regulation should specify a unifo rm design and content for the label for 
household tumble driers, in cluding gas-fired driers. 
(8) In addition, this Regulation should specify requirements as to the "technical 
documentation" and the "product fiche" for household tumble driers. 
(9) Moreover, this Regulation should specify requirements as to the information to be 
provided for any form of distance selling a nd advertisement of household tumble driers 
and any form of technical promoti onal material for such appliances. 
(10) It is appropriate to provide for a review of this Regulation in or der to take into account 
technological progress. 
(11) In order to facilitate the transition from Directive 95/13/EC to this Regulation, 
household tumble driers labelled in acco rdance with this Regulation should be 
considered as compliant with Directive 95/13/EC.  
(12) Directive 95/13/EC shou ld therefore be repealed.

2. C ALCULATION OF THE WEIGHTED CONDENSATION EFFICIENCY  
The condensation efficiency of a programme is the ratio between the mass of moisture 
condensed and collected in  the container of a condenser tumb le drier and the mass of moisture 
removed from the load by the programme, the la tter being the difference between the mass of 
the wet load before drying and the mass of the test load after drying. For calculating the weighted condensation efficiency, the average co ndensation efficiency for the standard cotton 
programme at both full and part ial load is considered.  
The weighted condens ation efficiency ( C
t) of a programme is calculated as a percentage and 
rounded to the nearest whole percent as:  
Ct = (3 × Cdry + 4 × Cdry½)/7 
where: - C
dry = average condensation efficiency of the standard cotton progr amme at full load; 
- C dry½ = average condensation efficiency of th e standard cotton pr ogramme at partial 
load. 
The average condensation efficiency C is calculated from the condensation efficiencies of test 
runs and expressed as a percentage:
