39、2009 without any modification. DIN EN ISO 11203:2010-01 Introduction 0.1 This International Standard specifies methods for determining the emission sound pressure levels at a work station and at other specified positions in the vicinity of machinery and equipment from the sound power level. In gener
40、al, these sound pressure levels are different from those that would be observed when the machinery or equipment is oper- ating in its normal surroundings where the environment may influence the emission sound pressure level. 0.2 This International Standard is one of a series (IS0 11200 to IS0 11204)
41、 which specifies various methods for determining the noise emissions of a piece of machinery or equipment, or a sub-assembly of such equipment (machine under test). IS0 11200 gives guidance on the choice of the method to be used to determine the emission sound pressure levels of machinery and equipm
42、ent. It also gives details of International Standards giving methods for the de- termination of sound power levels. EN ISO 11203:2009 (E) DIN EN ISO 11203:2010-01 41 Scope 1 .I General This International Standard specifies two methods for determining the emission sound pressure levels of machinery a
43、nd equipment, at a work station and at other specified positions nearby, by calculation from the sound power level. The principal purpose of this determination is to permit comparison of the per- formance of different units of a given family of ma- chinery or equipment, under defined environmental c
44、onditions and standardized mounting and operating conditions. The data obtained may also be used for the declaration and verification of emission sound pressure levels as specified in IS0 4871. Emission sound pressure levels are determined with the same frequency weighting and time weighting, or in
45、the same frequency bands, as those for which sound power levels have been determined. NOTES I The contents of this and related International Standards are summarized in table 1 of IS0 11200:1995. 2 At any given position in relation to a particular machine, and for given mounting and operating condit
46、ions, the emis- sion sound pressure levels determined by the method of this International Standard will in general be lower than the directly measured sound pressure levels for the same ma- chine in the typical workroom where it is used. This is due to reverberation and the contributions of other ma
47、chines. A method of calculating the sound pressure levels in the vicinity of a machine operating alone in a workroom is given in IS0 11690-3. Commonly observed differences are I dB to 5 dB, but in extreme cases the difference may be even greater. 1.2 Types of noise and noise sources This Internation
48、al Standard is, in principle, applicable to moving or stationary machines, for indoor or out- door use, particularly those machines which are mass-produced. The methods given in this Inter- national Standard are not applicable to highly direc- tional sound sources used outdoors. This International S
49、tandard is particularly applicable to machines whose largest dimension is less than or equal to 1 m. It is also applicable to larger machines in certain cases (see 6.2.3). This International Standard is applicable to all types of noise as defined in IS0 2204 and IS0 12001 for which methods for determining the sound power level are available. 1.3 Test environment The test environment to be used is that which is sp
