Measurement Comparison for National Standards of Color Temperature
摘要
Abstract
To ensure the accuracy and consistency of the color temperature measurement system,the State Administration for Market Regulation organized a measurement comparison for national standards of color temperature in 2023.National Institute of Metrology(NIM)served as the pilot laboratory,while the National Institute of Measurement and Testing Technology(NIMTT)as a participating laboratory.Both laboratories used the national primary and secondary standards for color temperature to measure the 2 856 K color temperature point of two comparison lamps.The comparison results were evaluated using the normalized error En value.After analysis,the absolute values of the En values were 0.07 and 0.12,both much less than 1,indicating that the differences between the measurement results from the participating laboratory and the reference values were within reasonable expectations,and the comparison results were satisfactory.The results showed that the measurement results from the secondary standard for color temperature are consistent with those from the primary standard.关键词
