6、确本部分适用于环境试验设备在使用期间的周期检定,以区别产品的型式检验、出厂检验等;—增加了“规范性引用文件”一章;—在检定项目中,删除了“工作室内壁与工作空间温差”和“工作室内壁辐射系数”两个项目;—在“检定用主要仪器及要求”一章中,给出了仪器的扩展不确定度(k=2)的要求;—增加了“检定条件”一章;—对于温度测量点数量,设备的工作空间容积由“以1m,分界”改为“以2m“分界”,对于“大于2m“的设备”,温度和风速的测量点由21点减少为15点;—周期检定试验设备时,“温度偏差、相对湿度偏差”的测量时间缩短为30min;—在“数据处理与检定结果”中,给小了“温度偏差、温度波动度温度均匀度、
7、湿度偏差、温度变化速率、风速”的计算公式;增加了“环境参数场的调整”和“试验设备仪表修正值的范围”,并且对限用的范围给予了必要的说明;—本部分的附录中给出“干湿表法恻量相对湿度,;—删除了记录表格。本部分由中国电器工业协会提出本部分由全国电工电子产品环境技术标准化技术委员会归口。本部分起草单位:信息产业部电子第五研究所。本部分主要起草人:谢晨浩、赖文光。本部分所代替标准的历次版本发布情况:—GB/T5170.18-19870GB/T
