摘要:提供了對溫度和濕度氣候試驗箱內部環(huán)境條件進行不確定度分析的方法。首先介紹了測量的不確定度概念,然后討論容差的意義。考慮到濕度和溫度測量是采用確定和合成不確定度。結合校準空載試驗箱和有負載試驗箱的條件測量的案例。zui后,逐條整理成為范本用于分析結果以給出規(guī)范的不確定度評估依據。

Abstract:Provides the methods for analysing uncertainties of temperature and humidity in climatic test chambers. In what follows, the concept of uncertainty of measurement is introduced first and then the significance of tolerance discussed. Aspects of humidity and temperature measurement are considered, followed by methods for determining and combining uncertainties. The cases of both calibrating an empty chamber and of measuring conditions in a loaded chamber are considered. Finally, detailed guidance and worked examples are given for analysing results to give estimates of uncertainty in the measured performance.
