对新计量产品来说,进行型式评价环境试验是必需而且有重要意义的。相应的环境试验设备基本选用温湿度试验箱。对试验箱的温湿度测量一般选用具有温湿度修正值温湿度测量装置。其中,温湿度偏差是指试验箱的显示仪表示值与试验箱的中心点实际温湿度之差。文章结合型式评价的具体试验状况,根据大量试验数据,利用科学的分析方法,对型式评价试验设备的测量不确定度进行了评定,获得了可信的分析结果。
For new metrology products, it is necessary and important to carry out a type assessment environmental test. Corresponding environmental test equipment basic selection of temperature and humidity chamber. Temperature and humidity measurements on the test chamber generally use a temperature and humidity correction value of temperature and humidity measurement device. Among them, the temperature and humidity deviation is the difference between the display value of the test box and the actual temperature and humidity of the center of the test box. Based on a large number of experimental data and using scientific analysis methods, the article evaluates the measurement uncertainty of the type evaluation test equipment and obtains credible analysis results.
