EN ISO 11204:2010 (E) DIN EN ISO 11204:2010-10 Introduction This International Standard specifies a method for determining the emission sound pressure levels at a work station and at other well defined positions, i
45、n the vicinity of a machine or piece of equipment, in situ. It is one of a series (ISO 1120015to ISO 1120519) which specifies various methods for determining the emission sound pressure level at a work station and at other specified positions of a machine or equipment. ISO 1120015gives guidance on t
46、he choice of the method to be used to determine the emission sound pressure levels of machinery and equipment. The method specified in this International Standard differs from those of ISO 1120116in determining and applying a local environmental correction. It differs from ISO 1120217by using an exa
47、ct measurement of sound pressure levels on a reference measurement surface to determine the directivity of the sound radiation of the machine under test. The acoustical properties of the room have to be determined to qualify the test environment and to determine a correction for local environmental
48、influences applied to the measured sound pressure levels. With the method specified in this International Standard, results of accuracy grade 2 (engineering grade) or accuracy grade 3 (survey grade) are obtained. The method specified in this International Standard is generally applicable in situ. No
49、 assumptions about the directivity of the radiation or the source location are necessary, because this directivity is determined measuring the sound pressure levels on an enveloping surface. The grade of accuracy of the procedure with existing conditions can be qualified as engineering or survey. In general, the emission sound pressure levels are less than or equal to those that occur when the machine is operating in its normal surroundings.
