摘　　要：国家标准对于储水式电热水器能效测试用环境湿度计的测量准确度要求为±1%RH,与国外同类标准要求差异较大,较高的准确度要求配置测量仪器的成本较高,使用过程的要求相对严格而且费用高昂。分析了储水式电热水器的能效测试环境湿度要求,指出环境湿度对能效测量结果的影响可以忽略,通过对测量范围和测量准确度要求的分析,结合CTL决议的适用要求,确定准确度±6%RH即可满足使用要求,由此可见,GB 21519-2008和GB/T 20289-2006规定的准确度为±1%RH的要求,存在明显的不合理问题。The measurement accuracy requirement of the national standard for the ambient humidity meter for energy efficiency testing of storage type electric water heaters is±1%RH,which differs greatly from the requirements of similar foreign standards,and the higher accuracy requires the higher cost of configuring measuring instruments,and the requirements for the use process are relatively strict and expensive.Analyzed the environmental humidity requirements for energy efficiency testing of storage type electric water heaters and pointed out that the influence of environmental humidity on the energy efficiency measurement results can be ignored,and through the analysis of the measurement range and measurement accuracy requirements,combined with the applicable requirements of the CTL resolution,it is determined that an accuracy of±6%RH can meet the requirements for use,so the accuracy of±1%RH stipulated in GB 21519-2008 and GB/T 20289-2006 can meet the requirements for use.The requirement that the accuracy is±1%RH is an obviously unreasonable problem.
