Accredited testing laboratory AB 308. Professional noise and vibration measurements of machinery in accordance with EU directives.
AB 308
ILAC MRAAccredited sound power and sound pressure measurements for manufacturers and importers who must declare noise levels and demonstrate outdoor equipment compliance on the EU market.
One of the responsibilities of manufacturers and importers is to place only safe products on the EU market. Under Directive 2006/42/EC, the manufacturer or importer must inform users in the instruction manual about the noise levels emitted by machines.
Another obligation for machinery placed on the EU market is to demonstrate compliance with Directive 2000/14/EC on noise emission by equipment for use outdoors.
COCH is a PCA-accredited testing laboratory (AB 308, ILAC MRA) performing individual tests according to international standards — mainly to determine sound pressure and/or sound power levels.
Measurements performed at Laboratory AB 308 using engineering and survey methods — products, parameters and applied standards.
We provide independent measurements of noise parameters given in the manufacturer’s promotional materials (e.g. mandatory product cards). We can also support manufacturers with development tests to optimise product settings.
Determination of A-weighted sound power using engineering and survey methods per PN-EN ISO 3744, 3746 and 3747.
Noise at the operator station and in the work space — required for machinery documentation and workplace assessment.
Acoustic testing of air conditioners, liquid chillers, heat pumps, process chillers and dehumidifiers with electrically driven compressors.
Noise measured under defined operating conditions as a key parameter for HP KEYMARK certification of heat pumps.
Sound power determination for heat pump water heaters according to PN-EN 12102-2.
Noise emission measurements for household appliances within the accredited laboratory scope.
Sound power level of noise sources determined with intensity probes where applicable.
A-weighted sound pressure and calculated sound power across the laboratory measurement range 30–136 dB.
Our acoustic measurement chamber and precision instrumentation.
