Sound pressure level is measured with a calibrated sound level meter at defined positions around the machine while it operates in a specified mode. Prazamana carries out measurements per ISO 11202. Measurement positions and operating conditions are agreed for each machine.

Prazamana's noise testing is performed per ISO 11202, which covers the measurement of emission sound pressure levels at the work station and other specified positions. The Machinery Directive 2006/42/EC sets the requirement to reduce noise and provide noise emission information. Please confirm with the team which standards apply to your machine type.

Testing can be scoped for a machine you already have, for example to verify declared noise values before export. Since the measurement is of the machine in operation, it depends on being able to run the machine under the required conditions, so please describe your machine to the team.

The arrangement is agreed when the tests are scoped, depending on the machine and where it can be measured. Please contact the team to discuss on-site or other options for your equipment.

There is no single noise limit for every machine: the requirements are to reduce noise as far as practicable and to declare accurate values, and workplace exposure limits are set by local rules. If a machine is louder than expected, the usual steps are to identify the main noise sources and reduce them, for example with enclosures, damping or design changes, and then re-measure. Please discuss your case with the team.

Test results are normally kept in the machine's technical documentation, and the declared noise values appear in the instructions for the machine. The exact format of the report is agreed for each project, so please ask the team what you will receive.
