标准范围

ISO 2889:2010对核设施管道和烟囱排出空气中的气载放射性物质取样系统的设计和使用提出了基于性能的标准和建议。ISO 2889:2010的要求和建议旨在为法规遵从性和系统控制进行采样。如果现有空气取样系统的设计不符合ISO 2889:2010的性能要求和建议，建议对系统的性能进行评估。如果发现缺陷，建议确定是否需要进行改造，并且是否可行。仅为正常操作设计的取样系统不可能在所有条件下满足ISO 2889:2010的要求。在非正常条件下，ISO 2889:2010的标准或建议仍然适用；但对于事故情况，可能需要特殊或单独的事故空气取样系统。

ISO 2889:2010 sets forth performance-based criteria and recommendations for the design and use of systems for sampling of airborne radioactive materials in the effluent air from the ducts and stacks of nuclear facilities.The requirements and recommendations of ISO 2889:2010 are aimed at sampling that is conducted for regulatory compliance and system control. If existing air-sampling systems are not designed to the performance requirements and recommendations of ISO 2889:2010, an evaluation of the performance of the system is advised. If deficiencies are discovered, a determination of whether or not a retrofit is needed and practicable is recommended.It can be impossible to meet the requirements of ISO 2889:2010 in all conditions with a sampling system designed for normal operations only. Under off-normal conditions, the criteria or recommendations of ISO 2889:2010 still apply; but for accident conditions, special or separate accident air sampling systems can be necessary.
