창호 단열성 시험의 교정시험 측정불확도 추정 및 계측인자 기여율 분석

Thermal resistance test of windows and doors is required calibration test, which ‘calibration test of the surface air-film resistance by CRM(Certified reference material)’ and ‘Correction calorimetric test of guarded hot box and edge of surrounding panel by CRM’. These two calibration test involve many metrics and complex procedures, which can lead to reliability problems in test results. In addition, it is necessary to understand the calibration test and to find a way to lower the uncertainty of measurement by analyzing contribution rate of the measurement factors. This paper is a follow up study of 「Estimation on Uncertainty of Measurement on Thermal Resistance Test for Windows And Doors」 and perform the uncertainty of measurement estimation of calibration test excluded from follow up study. As a result, the uncertainty of measurement estimation procedure for the thermal resistance test for windows and doors is proposed. In addition, according to analysis of the contribution rate of the measurement factor, the contribution rate of surface air-film resistance of warm side(R i ) was the highest at 49.643%.
