22、ps, and dehumidifiers with electrically driven compressors. Some of them are specifically adapted to provide results with low uncertainties, by using laboratory class acoustic methods and highly controlled operating conditions. Those measurements are suitable for certification, labelling and marking
23、 purposes.In some cases, the target and/or the environment of the measurements do not allow such precisionclass methods. This European Standard also offers ways to assess sound power levels with acceptable accuracy even though acoustic methods and/or operating conditions are not laboratorytype, e.g.
24、 in situ or quality control measurements.This European Standard gives two classes of measurements and results, according to the test environment: Class A measurements correspond to controlled operating conditions (standard or application rating conditions). It is defined by the respect to the tolera
25、nces of Table 2 and will be used for the conformity to requirements of: The Commission Regulation (EU) No 206/2012 of 6 March 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for air conditioners; Commission Delegated Regulat
26、ion (EU) No 811/2013 of 18 February 2013 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to the energy labelling of space heaters, combination heaters, packages of space heater, temperature control and solar device and packages of combination heater, temp
27、erature control and solar device; The Commission Regulation (EU) No 813/2013 of 2 August 2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for space heaters and combination heaters; The Commission Delegated Regulation (EU) No
28、626/2011 of 4 May 2011 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to energy labelling of air conditioners. Class B measurements correspond to the case where the range defined by the tolerances of Table 2 cannot be fulfilled.In both classes, precision
29、 or engineering class acoustic methods need to be applied. The choice of the acoustic measurement method is done in accordance with EN ISO 3740 and the EN ISO 9614 series depending on the type of surrounding acoustic fields (diffuse or free field, enclosed or open space), and the available instrumen
30、tation. The reference of acoustic standard needs to be reported with explicit mention of its accuracy class, whatever the current operating conditions.The use of EN ISO 3746 and EN ISO 3747 as survey grade methods are not recommended due to the high level of uncertainties. Their use is only allowed
31、for non-controlled environments when they fulfil the engineering grade requirement.Three methods for determining the sound power levels are specified in order to avoid unduly restricting existing facilities and experience: the first methodology is based on reverberation room measurement (see EN ISO
32、3741 and the EN ISO 3743 series); the second method is based on measurements in an essentially free field over a reflecting plane (see EN ISO 3744 and EN ISO 3745); the third method is based on sound intensity measurement (see the EN ISO 9614 series) preferably in a free field environment.3BS EN 121
33、021:2017EN 12102-1:2017 (E)The necessity to maintain the test conditions obviously leads to recommend test methods implemented in acoustically designed (enclosed) spaces, such as EN ISO 3741, the EN ISO 3743 series, EN ISO 3745 and also the EN ISO 9614 series when implemented in an enclosed space.Th
34、e open spaces will be used only in specific cases, e.g. when the size or the capacity of the unit under test cannot be managed by standard test rooms. Suitable test methods are EN ISO 3744 and the EN ISO 9614 series.NOTE Intensity measurement methods are quite robust and are well suited for tests to
35、 be done in environments without or with a light acoustic treatment (the better the acoustic treatment, the easier the implementation).4BS EN 121021:2017EN 12102-1:2017 (E)European foreword 2Introduction . 3European foreword 7Introduction . 81 Scope 102 Normative references .103 Terms, definitions a
