1 Scope

GB/T 18922-2008 is the Chinese national standard on methods of color specification for architecture, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 26 May 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2008. Classification: ICS 17.180.20, CCS A26. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the color representation and building construction color color card (referred to as the building color card) chromaticity values. This standard applies to architectural design, construction, building materials, decoration, environmental design and other areas of quantitative color representation; also suitable For the production of construction and select color cards.

3 Building color representation

3.1 label and coding Building color representation expressed by Chinese numerals and the corresponding color system building color coded. Appendix A of each color are marked on the label of the Chinese color system and the corresponding color-coded construction.

3.2 List row Select 1026 kinds of commonly used building colors, arranged in 171 rows, each row in the table 6, Appendix A.

3.3 Encoding Rules Building color coding rule according to the row and column values \u200b\u200bby four consecutive Arabic numerals coding, front row three yards after a column code. 1st row as an encoded as 0011, encoding the first five of the first 18 rows of 0185, the first six of the coding line 132 to 1326, and then click analogy.

4 Architectural Color Card

4.1 Definitions Architectural building color color card is the higher frequency of physical samples.

4.2 The color selection Building color color card selection from Appendix A, the number of colors can be selected according to actual needs, arranging method according to architectural color coding Identification code, the use of premises and habits.

4.3 Calibration of colorimetric values Each building color color card shall be calibrated according to their color values \u200b\u200band tristimulus values \u200b\u200band chromaticity coordinates GB/T 3979 determined. Construction color Chroma value card shall be GB/T 15608 requirements.

4.4 color CIE1976Lab uniform color space and color difference equation building color card with color in 7921 with GB/T standard computing architecture color card Color chromaticity set value and the standard value DeltaEab, with DeltaE ab Evaluation of the production of precision building color cards. Architectural Color Card color calibration DeltaEab<=3 chroma value and its standard value.
