随着供热改革的不断推进,热计量在全国各地逐步深入,热量表在供热计量领域的安装、使用逐年增加,随之而来的是热量表的耐久性问题受到各方关注。试验过程中,耐久性试验持续时间、试验温度、流量条件、试验环境等各种具体要求应予以明确,以确 With the continuous promotion of heat supply reform, heat metering has been gradually deepened in all parts of the country. The installation and use of calorimeters in the field of heat metering have been increasing year by year. The consequent problem of the heat meter’s durability has drawn the attention of all parties. During the test, the specific requirements of durability test duration, test temperature, flow conditions, test environment and so on should be clear and definite
