1965年，CIE推荐了一种基于测试色样方法的测量和规定光源显色性能的程序。该方法在1974年进行了更新，考虑到了颜色适应的变化。在过去的20年里，观察到了几处印刷错误，并不时出版更正后的再版。CIE 13.3-1995是CIE 13.2-1974的修正版，已更新为最新版本，以呈现光谱辐射测量和计算实践。技术建议没有改变。根据本出版物计算CIE显色指数的两个计算机程序可用于“DOS”- 在DOS或“MS-WINDOWS”环境中运行的计算机，如CIE D008。本技术报告建立了CIE推荐的基于测试对象产生的色移测量和规定光源显色性能的方法，称为“测试色法”。它是评估光源显色性能的基本方法，建议用于型式试验以及单个灯具的试验。本规范适用于大多数通用光源（如钨丝灯、管状荧光灯和所有其他类型的气体放电灯，但主要是单色辐射源，如低压钠等除外）。 )。此方法也可应用于修改后的日光。评级包括一个通用显色指数，该指数可由一组特殊显色指数补充。特殊显色指数的推导基于CIE 1964统一空间中色差向量长度的一般比较。为了应用推荐的测试颜色方法，必须计算适当选择的测试颜色样品的合成色移。一组八个测试色样由其光谱辐射系数指定，用于计算通用显色指数。这些样品覆盖色调圈，饱和度适中，亮度大致相同。 此外，还提供了另外六个测试颜色样本的数据，这些样本代表强烈的红色、黄色、绿色和蓝色，以及肤色和树叶颜色。从颜色变化中，可以找到显色指数。技术报告以英文编写，并附有法文和德文的简短摘要。它包含20页，2个表格。本技术报告基于CIE 13.2-1974。

The CIE recommended in 1965 the procedure of measuring and specifying colour rendering properties of light sources, based on a test colour sample method. This method was updated in 1974 taking the chromatic adaptation shift into account. During the past 20 years several misprints were observed and corrected reprints were published from time to time. CIE 13.3-1995 is the corrected version of CIE 13.2-1974 that has been brought up to date to present spectroradiometric and calculation practice. The technical recommendations have not been changed.Two computer programs to calculate the CIE colour rendering indices according to the present publication are available for "DOS"-computers to be run in a DOS or in an "MS-WINDOWS" environment as CIE D008.This Technical Report establishes the CIE recommended method of measuring and specifying colour rendering properties of light sources based on resultant colour shifts of test objects, referred to as the "Test-colour Method". It is the fundamental method for appraisal of colour rendering properties of light sources, and is recommended for type testing as well as for testing individual lamps.This specification applies to most general purpose illuminants (e.g. tungsten filament lamps, tubular fluorescent lamps, and all other kinds of gaseous discharge electrical lamps except sources of predominantly monochromatic radiation such as low pressure sodium, etc.). This method may also be applied to modified daylight.The rating consists of a General Colour Rendering Index which may be supplemented by a set of Special Colour Rendering Indices. The derivation of the Special Colour Rendering Indices is based on a general comparison of the length of colour difference vectors in the CIE 1964 Uniform Space.To apply the recommended Test-Colour Method the resultant colour shifts for suitably chosen test-colour samples must be calculated. A set of eight test-colour samples is specified by their spectral radiance factors for calculating the General Colour Rendering Index. These samples cover the hue circle, are moderate in saturation, and are approximately the same in lightness. Data for six additional test-colour samples representing a strong red, yellow, green and blue as well as complexion and foliage colours are also supplied. From the colour shifts, Colour Rendering Indices may be found.The Technical Report is written in English, with a short summary in French and German. It contains 20 pages, with 2 tables.This Technical Report is based in CIE 13.2-1974.
