摘要:提供了對(duì)溫度和濕度氣候試驗(yàn)箱內(nèi)部環(huán)境條件進(jìn)行不確定度分析的方法。首先介紹了測(cè)量的不確定度概念,然后討論容差的意義??紤]到濕度和溫度測(cè)量是采用確定和合成不確定度。結(jié)合校準(zhǔn)空載試驗(yàn)箱和有負(fù)載試驗(yàn)箱的條件測(cè)量的案例。zui后,逐條整理成為范本用于分析結(jié)果以給出規(guī)范的不確定度評(píng)估依據(jù)。

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.
