GB/T 28197-2011Methods for characterizing tristimulus colorimeters for measuring the colour of light (English PDF)

Foreword

This standard is based on GB/T 1.1-2009 and GB/T 20000.2-2009 provisions prepared.

This standard uses redrafted law revision adopted CIE179-2007 "measuring method characterized by light color colorimeter tristimulus values." this standard CIE179-2007 compared with more adjustments in the structure, listed in Appendix A of this standard and CIE179-2007 Reg number control list.

The standard proposed by China National Light Industry Council.

This standard by the National Standardization Technical Committee Lighting optical radiation measurement Technical Committee (SAC/TC224/SC3) centralized.

This standard was drafted. Hangzhou distance Optoelectronic Information Co., Ltd., China Testing Technology Research Institute, Hangzhou Quality and Technical Supervision Inspection Institute, Guangdong Product Quality Supervision and Inspection Institute, China Institute of Metrology, Ministry of Public Security Traffic Management Science Institute.

Introduction

This standard is intended to measure the color of the light with the tristimulus provide objective performance evaluation method colorimeters. In the tri-stimulus values \u200b\u200bof the colorimeter Energy parameters, some value can be quantified, some can not be quantified, can only be described qualitatively.

This standard gives a number of sources of measurement error.

Potential users of this standard can be used as tristimulus colorimeters, the user and the manufacturer's instructions or guidelines for evaluation of the quality of the instrument.

The performance parameters of this standard may also be listed as a guide for manufacturers to improve colorimeter instrument.

Light source color values \u200b\u200busing tristimulus colorimeter Characterization

1 Scope

This standard specifies the measuring light source chromaticity coordinates of tristimulus values \u200b\u200bcharacterization method colorimeter.

This standard applies to all kinds of offers illuminance or luminance values \u200b\u200bmeasured with light color tristimulus colorimeters with built-in light source for measuring Reflective and transmissive material color chromaticity instrument is not within the scope of this standard.
