标准范围

基于在指定视场上对测试表面的观察，通过物镜的移动聚焦最高峰值和最低谷。通过移动物镜来确定最高峰和最低谷之间的距离（峰谷高度），以便聚焦在同一视野内的最低谷。重复该程序，获得另外19个不同视野的值，计算算术平均值。还规定了聚焦显微镜。该程序也适用于测定基本平面喷砂清理钢的表面轮廓。

Based on observation of the test surface over a specified field of view, focussing the highest peaks and lowest valleys by movement of the objective. Determination of the distance (peak-to-valley height) between the highest peak and lowest valley by movement of the objective in order to focus on the lowest valley within the same field of view. Repetition of the procedure to obtain values for a further 19 different fields of view, calculation of the arithmetic mean. The focussing microscope is also specified. The procedure is also applicable to the determination of the surface profile of essentially planar blast-cleaned steel.
