ANNEX III Measurements and calculations 1. 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. They shall meet the conditions and technical parameters set out in points 2 to 6. 2. General conditions for measurements and calculations (a) Solid fuel boilers shall be tested for the preferred fuel and any other suitable fuels indicated in Table 1 of Annex II, with the exception that boilers tested for chipped wood with a moisture content of more than 35 % meeting the applicable requirements are considered to also meet such requirements for chipped wood with a moisture content of 15-35 % and are not required to be tested for chipped wood with a moisture content of 15-35 %. (b) Declared values for seasonal space heating energy efficiency and seasonal space heating emissions shall be rounded to the nearest integer. (c) Any solid fuel heat generator designed for a solid fuel boiler, and any solid fuel boiler housing to be equipped with such a heat generator, shall be tested with an appropriate solid fuel boiler housing and heat generator. 3. General conditions for seasonal space heating energy efficiency (a) The useful efficiency values η n , η p and the useful heat output values P n , P p shall be measured, as appropriate. For solid fuel cogeneration boilers the electrical efficiency value η el,n is also measured. (b) The seasonal space heating energy efficiency η s shall be calculated as the seasonal space heating energy efficiency in active mode η son , corrected by contributions accounting for temperature controls, auxiliary electricity consumption, and, for solid fuel cogeneration boilers, by adding the electrical efficiency multiplied by a conversion coefficient CC of 2,5. (c) The consumption of electricity shall be multiplied by a conversion coefficient CC of 2,5. 4. Specific conditions for seasonal space heating energy efficiency (a) The seasonal space heating energy efficiency η s is defined as: η s = η son – F(1) – F(2) + F(3) where: (1) η son is the seasonal space heating energy efficiency in active mode expressed as a percentage, calculated as set out in point 4(b); (2) F(1) accounts for a loss of seasonal space heating energy efficiency due to adjusted contributions of temperature controls; F(1) = 3 %; (3) F(2) accounts for a negative contribution to the seasonal space heating energy efficiency by auxiliary electricity consumption, expressed as a percentage, and is calculated as set out in point 4(c); (4) F(3) accounts for a positive contribution to the seasonal space heating energy efficiency by the electrical efficiency of solid fuel cogeneration boilers, expressed as a percentage, and is calculated as follows: F(3) = 2,5 × η el,n (b) the seasonal space heating energy efficiency in active mode, η son , is calculated as follows: (1) for manually stoked solid fuel boilers that can be operated at 50 % of the rated heat output in continuous mode, and for automatically stoked solid fuel boilers: η son = 0,85 × η p + 0,15 × η n (2) for manually stoked solid fuel boilers that cannot be operated at 50 % or less of the rated heat output in continuous mode, and for solid fuel cogeneration boilers: η son = η n (c) F(2) is calculated as follows: (1) for manually stoked solid fuel boilers that can be operated at 50 % of the rated heat output in continuous mode, and for automatically stoked solid fuel boilers: F(2) = 2,5 × (0,15 × el max + 0,85 × el min + 1,3 × P SB )/(0,15 × P n + 0,85 × P p ) (2) for manually stoked solid fuel boilers that cannot be operated at 50 % or less of the rated heat output in continuous mode, and for solid fuel cogeneration boilers: F(2) = 2,5 × (el max + 1,3 × P SB )/P n 5. Calculation of gross calorific value The gross calorific value ( GCV ) shall be obtained from the gross calorific value moisture free ( GCV mf ) by applying the following conversion: GCV = GCV mf × (1 – M ) where: (a) GCV and GCV mf are expressed in megajoules per kilogram; (b) M is the moisture content of the fuel, expressed as a proportion. 6. Seasonal space heating emissions (a) Emissions of particulate matter, organic gaseous compounds, carbon monoxide and nitrogen oxides shall be expressed standardised to a dry flue gas basis at 10 % oxygen and standard conditions at 0 °C and 1 013 millibar. (b) The seasonal space heating emissions E s of respectively particulate matter, organic gaseous compounds, carbon monoxide and nitrogen oxides are calculated as follows: (1) for manually stoked solid fuel boilers that can be operated at 50 % of the rated heat output in continuous mode, and for automatically stoked solid fuel boilers: E s = 0,85 × E s,p + 0,15 × E s,n (2) for manually stoked solid fuel boilers that cannot be operated at 50 % or less of the rated heat output in continuous mode, and for solid fuel cogeneration boilers: E s = E s,n where: (a) E s,p are the emissions of respectively particulate matter, organic gaseous compounds, carbon monoxide and nitrogen oxides measured at 30 % or 50 % of rated heat output, as applicable; (b) E s,n are the emissions of respectively particulate matter, organic gaseous compounds, carbon monoxide and nitrogen oxides measured at rated heat output. (c) Emissions of particulate matter shall be measured by a gravimetric method excluding any particulate matter formed by organic gaseous compounds when flue gas is mixed with ambient air. (d) Emissions of nitrogen oxides shall be calculated as the sum of nitrogen monoxide and nitrogen dioxide, and expressed in nitrogen dioxide.
