摘要
本文以IMDRY300-Ⅱ型双平板法导热系数测定仪为被校准仪器,根据JJF(苏)98-2010《导热系数测试仪校准规范》,分别使用绝热材料导热系数参比板、薄膜温度计和温度巡检仪对其导热系数示值误差、热板和冷板温度示值误差、平均温度和均匀度进行校准,对校准结果进行不确定度评定。
The IMDRY300-Ⅱdouble plate thermal conductivity tester was calibrated according to JJF(Su)98-2010"Calibration Specification for Thermal Conductivity Tester".The thermal conductivity reference plate of thermal insulation material,thin film thermometer and temperature inspection instrument were used respectively for calibrating the indication error of thermal conductivity,the temperature indication error,average temperature and uniformity of hot plate and cold plate,and the uncertainty of the calibration results were evaluated.
