The colors and chromaticity ranges of light signals of navigation aids Subject content and scope of application
This standard specifies the colors and chromaticity ranges of light signals of navigation aids. This standard applies to various light signals of navigation aids in China's sea areas and inland waters. 2 Colors and chromaticity ranges of light signals of navigation aids 2.1 The colors of light signals of navigation aids adopt the four-color system of white, red, green and yellow. 2.2 Chromaticity ranges of light signals of navigation aids. 2.2.1 The boundary equations of the chromaticity ranges of white, red, green and yellow lights are shown in Table 1.

3 It is prohibited to use any other light color and chromaticity range other than those specified in this standard 0.
No department shall use any other light color other than those specified in this standard as the color of navigation light signal. The chromaticity values ​​of white, red, green and yellow lights, regardless of the color filter material used, shall be within the corresponding chromaticity range specified in this standard.:com Additional Notes:
This standard was proposed by the Ministry of Communications of the People's Republic of China and is under the jurisdiction of the Standard Design Committee of the Ministry of Communications. This standard was drafted by the Shanghai Navigational Aids Factory of the Ministry of Communications. 12708—91
The main drafters of this standard are Zhou Zengjia, Su Cuo and Qi Jinfu. This standard is equivalent to the light signal colors and chromaticity ranges recommended by the International Association of Lighthouse Authorities (ILA) in December 1977 "Recommendations for the colours of light signals on aids to navigatian december 1977".
