Microscope and image analysis technique are adopted in 《JB/T 7990-1998》. The "grain size" tested by microscope is expressed by the "largest breadth" of the grain image. When the grain size is tested by image analysis instrument, the grain size is expressed by the diameter of a circle whose area equals the grain image's.

JB/T7990-1998》规定用图像分析仪或显微镜测量粒度，显微镜法测量的"粒度"是以颗粒投影的"最大宽度"来表征的，而用图像分析仪测量的"粒度"指的是"等面积圆直径"，即，用与颗粒投影面积相等的圆的直径表征颗粒粒度。
