摘要
随着国家标准"天然气能量的测定"(GB/T 22723-2008)的发布,天然气能量计量的实施已经进入倒计时阶段;与此同时,该标准实际上也明确了在实施能量计量之后,商品天然气的发热量与其体积流量一样,都将属于法制计量范畴。但就法制计量的要求而论,当前尚缺少一个有关天然气分析溯源准则的国家标准,建议尽快建立并发布。
With the issuance of national standard about ＂determination of natural gas energy＂（GB/T 22723-2008）,the implementation of natural gas energy measurement has stepped into the countdown stage.Meanwhile,this standard has defined that calorific value of commercial natural gas will belong to legal metrology domain just like the volume value after the implementation of energy measurement.As far as the demand of legal metrology is concerned,there is a lack of one national standard about the tracing standard of natural gas analysis at present,so it is suggested to establish and publish it as quickly as possible.
