全国标准色板量值比对实验分析

Experimental analysis on the national comparison of value of quantity for color standard plates

为公正、科学、客观地了解我国标准色板量值传递能力,全国光学计量技术委员会组织全国标准色板量值(CIE三刺激值及色品坐标)比对,全国省级计量技术机构及部分国防量传机构共20家实验室参加。实验分析阐述全国标准色板量值比对的实验背景和实施过程,包括比对方案设计、样品制备、均匀性、稳定性考察、结果统计等,并对比对结果进行分析。结果显示:标准色板测量能力满意度为99.68%(3家复测),参加量值比对的绝大多数实验室可以根据标准色板检定规程对标准色板的色度参数进行准确测量,我国开展标准色板检定和校准的实验室具有较高的技术水平。

In order to fairly, scientifically and objectively reflect the quantity transmission capability of color standard plates, National Committee for Optical Metrology Technology organized the national comparison of value of quantity （CIE 3 stimulus values and the chromaticity coordinates） for color standard plates, 20 laboratories from provincial institute of metrology and part of the national defense laboratory took part in the comparison. The experimental analysis mainly introduced the background and the implementation process of the comparison,including project design,sample preparation,homogeneity and stability test, results statistic and analysis,etc. The results showed that 99.68% measured data have satisfactory results （three of them retested）. In conclusion,most laboratories taking part in the national comparison have good competence in object color measurement, the technological level of verification and calibration is relatively high for most laboratories.
