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 positions1 Scope This International Standard is the frame standard introducing the basic group, ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205, on the determination of emission sound pressure levels at work stations and other specified positions. It gives guidance for: facilitating the writing of noise test codes; providing physical explanations of this noise emission quantity compared to other noise quantities (see 4. 1 to 4. 3); comparing the

– are intended for use in circumstances where encoding/decoding speed is the major concern in the choice of encoding rules

This part of IEC 60898 applies to DC circuit-breakers
