标准范围

ISO/TR 22520:2005提供了从不同制造商和其他官方来源获得的2002年便携式手持式林业机械A加权发射声压级的比较数据。它适用于链锯（现有的排放声压级适用于各种发动机尺寸）以及割草机和刷子切割机。国际标准ISO 11681-1、ISO 11681-2和ISO 11806要求，这些机器的设计应基于现有的噪声排放数据，产生尽可能低的噪声级，ISO/TR 22520旨在帮助确定是否符合该要求。

ISO/TR 22520:2005 provides comparative data, obtained from various manufacturers and other official sources, for the year 2002, on the A-weighted emission sound pressure levels of portable hand-held forestry machinery. It is applicable to chain saws (for which the existing emission sound pressure levels were for the full range of engine sizes) and to grass-trimmers and brush-cutters. International Standards ISO 11681-1, ISO 11681-2 and ISO 11806 require that these machines be designed to generate noise levels as low as practicable, based on the existing noise emission data, and ISO/TR 22520 is intended to assist in determining compliance with that requirement.
