- 摘要:
- 强制性国家标准GB 17820-2018 《天然气》于2018年11月发布,该标准对一系列气质标准仲裁方法作出了规定。从仲裁(分析)方法的定义出发,指出确定仲裁方法的首要条件是其必须具有较高的准确度。同时,在讨论分析化学计量学溯源链技术模型的基础上,阐明不同层级的标准气混合物(RGM)和标准测量方法是构成溯源链的基本要素。最后,综合上述两个方面的讨论结果指出:强制性国家标准GB 17820-2018 《天然气》规定的一系列气质标准仲裁方法存在若干宜进一步探讨的技术问题。鉴于此,建议有关部门予以充分重视,并组织有关专家展开深入讨论以统一认识。
The mandatory national standard Gb17820-2018 "Natural Gas" was issued in November 2018, which stipulates a series of arbitration methods for natural gas quality.Starting from the definition of arbitration (analysis) method, it is pointed out that the primary condition of determining arbitration method is its high accuracy.At the same time, on the basis of discussing and analyzing the technical model of chemometrics traceability chain, it is clarified that different levels of reference gas mixture (RGM) and standard metering methods are the basic elements of traceability chain.Finally, based on the above discussion, it is pointed out that there are some technical issues that require further discussion in a series of gas quality standard arbitration methods stipulated in the mandatory national standard of Gb17820-2018 "Natural Gas".For this reason, it is suggested that the relevant authorities pay full attention to it and conduct in-depth discussions to unify the understanding.
