BS ISO 230-5. Test code for machine tools Part 5. Determination of the noise emission
|Standard number:||20/30379058 DC|
|Status:||Draft for Comment|
This standard 20/30379058 DC BS ISO 230-5. Test code for machine tools is classified in these ICS categories:
- 17.140.20 Noise emitted by machines and equipment
- 25.080.01 Machine tools in general
This noise test code specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the noise emission characteristics of machine tools.
Noise emission characteristics include emission sound pressure levels at workstations and the sound power level. The determination of these quantities is necessary for:
manufacturers to declare the noise emitted;
comparing the noise emitted by machine tools in the family concerned;
purposes of noise exposure risk assessment by the user of the machine tool.
The use of this noise test code ensures reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used. Noise measurement methods referred to in this standard are accuracy grade 2 (engineering grade) or accuracy grade 3 (survey grade).
Accuracy grade 2 is preferred with the benefit of having a lower measurement uncertainty, accuracy grade 3 is allowed.
