This paper gives several methods to validate these new methods by analyzing images of stage micrometer, metallurgical sample, and images that consisting of definite area in geometric graph, Several kinds of validation methods including of traceability of a quantity value, printing microstucture graph, comparing microstucture photo with standard photos, length meansurement, and area meansurement are discussed in this paper.

通过分析显微镜刻度尺图像、金相样品图像，及给定特定图形且已知面积的图像，依据ISO/IEC 17025检测和校准实验室能力的通用要求，并结合金相检验标准，阐述了金相显微镜利用新方法的方法确认，其中包括量值溯源、金相组织输出、图谱比较、长度类测量和面积类测量的确认方法。
