标准摘要
[中文适用范围]： 本部分ISO 8503规定了轮廓仪（触针式仪器）并描述了校准符合ISO 8503-1要求的ISO表面轮廓比较器的程序。本部分ISO 8503也适用于确定基本平面喷砂清理钢的表面轮廓，范围在Ry5 = 20 μm至Ry5 = 200 μm之间。该确定可在喷砂清理表面的代表性部分上进行，或者如果无法直接观察表面，则可在表面的复制品上进行（见附录C）。注：在适当的情况下，本程序可用于评估其他磨料喷砂清理基材的粗糙度轮廓。 [外文原描述]： ISO 8503-4:2012 specifies the stylus instrument and describes the procedure for calibrating ISO surface profile comparators conforming to the requirements of ISO 8503-1. It is also applicable to the determination of the surface profile, within the range 20 μm to 200 μm, of essentially planar blast-cleaned steel. The determination can be carried out on a representative section of the blast-cleaned surface or, if direct observation of the surface is not feasible, on a replica of the surface.
