ISO 11200 pdf download Acoustics — Noise emitted by machinery and equipment — Guidelines for the use of basic standards for the determination of emission sound pressure levels at a work station and at other specified positions
This International Standard is the frame standard introducing the basic group,ISO 11201, ISO 11202SO 11203,ISO 11204 and IS0 11205, on the determination of emission sound pressure levels at workstations and other specified positions.lt gives guidance for:
facilitating the writing of noise test codes;
providing physical explanations of this noise emission quantity compared to other noisequantities (see 41 to 4.3);
comparing the different measurement methods offered by the group (see Table 1);facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6)
This International Standard is largely based on flow charts and tables. Case studies are described
The guidance given applies to airborne sound only. lt is for use in noise testing, in general, and in thepreparation of noise test codes, in particular.
A standardized noise test code is intended to select standards from the ISO 11201,IS0 11202,ISO 11203.ISO 11204 and ISO 11205 group, which are the most appropriate to the machinery family it covers, andwhich give detailed requirements on mounting and operating conditions for the particular family,as welas the location ofthe work station/s) and other specified positions as prescribed in these InternationaStandards.
The data so obtained can be used for the declaration and verification of emission sound pressure levels.e.g.as specified in ISO 4871

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
Note 1 to entry: Noise emission descriptors can be incorporated into a product label and/or product specification.
The basic noise emission descriptors are the sound power level of the source itself and the emission sound pressure levels at a work station and/or at other specified positions (if any) in the vicinity of the source.
