林业机械. 噪声试验规程

[中文适用范围]： 本噪声测试规范规定了在标准条件下高效测量自走式林业机械噪声排放值所需的所有信息。它适用于 ISO 6814 定义的集材机、采伐机、加工机等。制造商需要确定这些参数，以便声明其噪声排放、比较同类机械以及在设计阶段进行噪声控制。 [外文原描述]： ISO 18564:2016 specifies all the information necessary for carrying out efficiently and under standardised conditions the noise emission values of self-propelled forestry machinery. It is applicable to fellers, bunchers, delimbers, forwarders, log loaders, skidders, processors, harvesters, mulchers and multi-function versions of these machine types, as defined in ISO 6814. Noise emission characteristics include A-weighted emission sound pressure values at the operator's station and the A-weighted sound power value. The determination of these quantities is necessary for the following: - manufacturers to declare the noise emitted; - comparing the noise emitted by machines in the family concerned; - purposes of noise control at the source at the design stage. NOTE For low-noise design, noise emission values in frequency bands are useful and the basic International Standards ISO 3744 and ISO 11201 can be used for determining noise emission quantities in frequency bands.
