摘要
不确定度是影响温度试验箱测量结果的重要指标。文章介绍了温度试验箱不确定度的评定方法,首先简述了不确定度的评定方法;然后给出了合成标准不确定度和扩展不确定度的计算公式;最后利用实例对温度试验箱的不确定度计算过程进行了说明。
Uncertainty is an important indicator affecting the measurement results of temperature test chambers. This paper introduces the evaluation method of uncertainty in temperature test chamber. Firstly, the evaluation method of uncertainty is briefly introduced. Then the calculation formula of synthetic standard uncertainty and extended uncertainty is given. Finally, the example is used to test the temperature test chamber, and the uncertainty calculation process is described.
