Foreword

This standard is based on technical report of the International Commission on Illumination CIE15.2004 "colorimetric" relevant content revision, and CIE15.2004 "Colorimetry" (in English) the degree of consistency is not equivalent. The main differences are as follows. --- Increase the reflection and transmission object color measurement method using spectrophotometric color measurement section, mainly for content measurement method of operation; --- Increase the reflection and transmission object color measured with a photoelectric colorimeter integral part of the law, mainly for content measurement method of operation; --- Increased by visual comparison of measurement methods for measuring object color content; --- Increased spectral photometer, optical instruments and integral side standard white color of the technical requirements. This standard replaces GB/T 3979-1997 "object color measurement method." Compared with the standard GB/T 3979-1997 The main changes are as follows. a) modify the "Scope" This part, the scope of the provisions of the object color measurement; b) modified (7) colorimeter colorimetric method for the optical integration method, an increase of photoelectric integration of color measurement Luther condition; c) increasing the visual comparison measurement method. The standard color by the National Standardization Technical Committee and centralized. This standard was drafted. China Institute of Metrology, Shenzhen Haichuan Industry Corp.. The main drafters of this standard. Chen Ping, Lin Yi Ge, Ma Yu, Chen-ya move, HE Wei-ping, Tang Hui Gong. This standard replaces the standards previously issued as follows. --- GB/T 3979-1983, GB/T 3979-1997. Object color measurement method

1 Scope

This standard specifies the object color spectrophotometric color measurement method, the photovoltaic integrator color measurement method and the measurement method of visual comparison. This standard applies to the reflection object color and object color measurement transmission, does not apply to the object containing the color measuring fluorescence.
