Resumen:
This noise test code specifies the information necessary to carry out efficiently and under standardised conditions the determination of the noise emission characteristics of portable hand-held, combustion engine powered forest machines such as chain saws, brush-cutters and grass trimmers. Noise emission characteristics include the A-weighted emission sound pressure level at the operator position and the A-weighted sound power level. It is intended for manufacturers' product control as well as type tests. It is intended that the results obtained can be used to compare different machines or different models of the same type of machine. Although the noise emission values determined are obtained in an artificial operation, they are representative of noise emission in a real work situation.
Diese Geräuschmessnorm legt die Angaben fest, die zur Durchführung einer effizienten Ermittlung der Geräuschemission von handgehaltenen forstwirtschaftlichen Maschinen mit Verbrennungsmotor unter genormten Bedingungen notwendig sind, wie Kettensägen, Freischneider und Grastrimmer. Die ermittelten Geräuschemissions-Kennwerte sind der A-bewertete Emissions-Schalldruckpegel am Ort der Bedienungsperson und der A-bewertete Schallleistungspegel. Diese Messnorm dient sowohl dem Hersteller zur Kontrolle seines Erzeugnisses als auch zur Ermittlung des Geräuschemissionswerts (Typprüfung). Der Zweck besteht darin, die ermittelten Werte zum Vergleich verschiedener Maschinen oder unterschiedlicher Modelle derselben Maschinenart verwenden zu können. Obwohl die Geräuschemissionswerte in einem Ersatz-Arbeitsverfahren ermittelt werden, sind sie für die Geräuschemission unter praktischen Arbeitsbedingungen repräsentativ.
