标准摘要
[中文适用范围]: 警告 - 应注意,在测试期间,特别是在关闭或拆除污染物控制系统期间,有害物质的浓度(如果存在)可能达到可能对操作人员或人员的健康造成风险的水平。 房间内有其他居住者。 ISO 29042 的这一部分不涉及控制这些风险所需的保护措施。 ISO 29042 的这一部分规定了污染物控制系统去污指数的测量方法,例如包括局部排气通风的捕获装置、喷水系统以及安装在机器上的分离设备(如果适用)。 该方法使用真实污染物(参见 ISO 29042-1:2008, 4.2),可在室内或现场环境中操作。 污染物控制系统去污指数的测量可用于: a) 机器污染物控制系统性能的评价; b) 污染物控制体系改进的评价; c) 类似设计机器污染物控制系统的比较; d) 根据净化效率对污染物控制系统进行排名; e) 确定排气系统达到给定水平时的空气流量; f) 确定机器污染物控制系统在净化效率方面的最新技术水平。 [外文原描述]: ISO 29042-9:2011 specifies a method for the measurement of the decontamination index of pollutant control systems, e. g. capture devices including local exhaust ventilation, water spray systems and, when appropriate, separation equipment installed on a machine. This method uses the real pollutant (see ISO 29042-1:2008, 4.2) and can be operated in room or field environments. Measurement of the decontamination index of a pollutant control system can serve for the: a) evaluation of the performance of a pollutant control system of a machine; b) evaluation of the improvement of a pollutant control system; c) comparison of pollutant control systems for machines of similar design; d) ranking of pollutant control systems according to their decontamination efficiency; e) determination of the air flow rate in the case of an exhaust system to achieve a given level; f) determination of the state of the art of pollutant control systems for machines with respect to the decontamination efficiency.
