标准范围
ISO 12141:2002描述了在标准条件下测量浓度低于50mg/m3的管道气流中低粉尘含量的参考方法。该方法已经过验证，特别强调5 mg/m3左右的区域。ISO 12141:2002已经针对废物焚烧炉排放的气流进行了开发和验证。更一般地说，它可以应用于来自其他固定源的排放，以及更高浓度。如果气体含有不稳定、反应性或半挥发性物质，测量将取决于取样和过滤处理条件。
ISO 12141:2002 describes a reference method for the measurement of low dust content in ducted gaseous streams at concentrations below 50 mg/m3 under standard conditions. This method has been validated with special emphasis on the region around 5 mg/m3.ISO 12141:2002 has been developed and validated for gaseous streams emitted by waste incinerators. More generally, it may be applied to emissions from other stationary sources, and to higher concentrations.If the gases contain unstable, reactive or semi-volatile substances, the measurement will depend on the sampling and filter treatment conditions.
