EVS-EN ISO 11202:2009

This International Standard specifies a method for determining the emission sound pressure levels of machinery or equipment, at a work station and at other specified positions nearby, in situ. A work station is occupied by an operator and may be located in open space, in the room where the source under test operates, in a cab fixed to the source under test, or in an enclosure remote from the source under test. One or more specified positions may be located in the vicinity of a work station, or in the vicinity of an attended or unattended machine. Such positions are sometimes referred to as bystander positions. NOTE 1 Throughout the document the word "source under test" is used to represent either a machine or a piece of equipment. Emission sound pressure levels are determined as A-weighted levels. Additionally levels in frequency bands and C-weighted peak emission sound pressure levels can be determined according to this International Standard, if required. NOTE 2 The contents of the ISO 11200 series (ISO 11201 to ISO 11205) are summarized in ISO 11200.
