ISO 12640-2:2004规定了一组15个标准彩色图像（编码为电子数据文件中提供的16位XYZ和8位RGB数字数据），可用于评估编码、图像处理（包括变换压缩和解压缩）、彩色监视器或打印期间的图像质量变化。它们可以用于许多图形技术应用，如研究、开发、产品评估和过程控制。

ISO 12640-2:2004 specifies a set of 15 standard colour images (encoded as both 16-bit XYZ and 8-bit RGB digital data provided in electronic data files) that can be used for the evaluation of changes in image quality during coding, image processing (including transformation compression and decompression), displaying on a colour monitor or printing. They can be used for many graphic technology applications such as research, development, product evaluation, and process control.
