CEN/TC 146/WG 8 - Ad hoc noise group

This standard specifies all the information necessary to carry out efficiently and under defined conditions the determination, information and verification of airborne noise emission from packaging machine covered by EN 415-1.
This measurement method specifies procedures for the determination of emission sound pressure levels at work station, at other specified positions and the sound power level on the basis of both the sound pressure level method and the sound intensity method. It also specifies installation and operating conditions.
This standard applies to machines covered by EN 415-1 as well as for any other packaging machine which are not covered by any other specific noise test code as well as for machines being part of packaging line. In such cases, all information relating to the assembly, installation and to the operating conditions as well as the arrangement of the work station shall be recorded and reported in the test report.
Noise emission characteristics include the following data:
- emission sound pressure level at work station  and at other specified positions;
- sound power emitted by machine.
Both can be used:
- to determine the noise emitted by machine;
- to inform on the noise emitted by the machine;
- to verify the noise emitted by the machine.
Noise emission values permit comparison of packaging machines on the market.
The use of this standard ensures the reproducibility of the determination of the characteristic noise emissions values within specific limits which will be determined by the grade of accuracy of the noise emission measuring method used.
