On page 27, Annex III is replaced as follows:

‘ANNEX III

Measurement methods and calculations referred to in Article 3

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 that take into account the generally recognised state-of-the-art methods.

1. GENERAL CONDITIONS FOR MEASUREMENTS AND CALCULATIONS

(1)	Declared values for seasonal space heating energy efficiency shall be rounded to the nearest one decimal place.

(2)	For electric local space heaters, declared values for nominal heat output shall be rounded to the nearest third decimal place. For all other local space heaters, declared values for nominal heat output shall be rounded to the nearest one decimal place.

(3)	Declared values for emissions shall be rounded to the nearest integer.

(4)	Where a parameter is declared pursuant to Article 4, its declared value shall be used by the manufacturer, importer or authorised representative for the calculations in this Annex.

(5)

For gas and liquid fuel local space heaters except commercial local space heaters, the flue gas temperature and the combustion air temperature shall be measured for the minimum total flue duct pipe length declared by the manufacturer in the installation manual but not more than 1,5 meters (sum of vertical and horizontal pipe length). If no declaration is available the measurement shall be performed with a total pipe length of 1,5 meters.

(6)	For separate related controls the correct functioning of the control functions shall be checked.

2. GENERAL CONDITIONS FOR SEASONAL SPACE HEATING ENERGY EFFICIENCY

(1)	The seasonal space heating energy efficiency (ηS ) shall be calculated as the seasonal space heating energy efficiency in active mode (ηS,on ), corrected by contributions accounting for heat output control, auxiliary electricity consumption and permanent pilot flame energy consumption.

(2)	For local space heaters that are placed on the market together with the control, the seasonal space heating energy efficiency shall be measured and calculated with the control contained in the packaging.

(3)

For local space heaters placed on the market without control, the seasonal space heating energy efficiency shall be measured and calculated for each different combination of local space heater and control functions indicated by the manufacturer, importer or authorised representative according to Annex II, point 4(2)(a).

3. GENERAL CONDITIONS FOR EMISSIONS

For gaseous and liquid fuel local space heaters the emissions of nitrogen oxides (NOx) shall be calculated as the sum of the measured nitrogen monoxide and nitrogen dioxide, and expressed in nitrogen dioxide. The measurement of nitrogen oxides emissions shall be concurrent with the measurement of the space heating energy efficiency.

For declaration and verification purposes the emission at full load NOx(max) applies.

If the power consumption of the low power modes can only be measured at a DC voltage level, the results of these measurements for each low power mode shall be multiplied with a factor 1,5, representing an average AC-DC power conversion of 67%, to arrive at the values that shall comply with the requirements for low power modes.
