机械安全.气载有害物质排放的评估.第8部分:污染物浓度参数测量的室内方法

[中文适用范围]： ISO 29042 的这一部分规定了一种室内方法，用于测量来自机器的给定空气传播有害物质的污染物浓度参数，该机器位于测试室并在规定条件下操作机器。 该方法仅适用于具有风量W500 m3/h的局部排气通风的机器和没有再循环空气的机器。 机器污染物浓度参数的测量可以用于： a) 机器性能的评价； b) 机器改进的评价； c) 具有相同预期用途的不同机器组内的机器比较（这些组由功能和加工材料定义）； d) 同一组机器按照污染物浓度参数进行排序； e) 确定机器的污染物浓度参数的现有技术水平。 [外文原描述]： ISO 29042-8:2011 specifies a room method for the measurement of the pollutant concentration parameter of a given airborne hazardous substance from machines, located in a test room and operating the machines under defined conditions. This method is applicable only to machines with a local exhaust ventilation with an air flow rate ≥500 m 3 /h and machines without recirculated air. Measurement of the pollutant concentration parameter of a machine can serve for the: a) evaluation of the performance of a machine; b) evaluation of the improvement of the machine; c) comparison of machines within different groups of machines with the same intended use (such groups being defined by the function and materials processed); d) ranking of machines from the same group according to their pollutant concentration parameters; e) determination of the state of the art of a machine with respect to its pollutant concentration parameter.
