Chinese Standard: GB/T 13288.4-2013

Preparation of steel substrates before application of paints and related products—Surface roughness characteristics of blast-cleaned substrates—Part 4:Method for the calibration of ISO surface profile comparator and for the determination of surface profile—Stylus instrument procedure

ISO 8503-4:1988

全国涂料和颜料标准化技术委员会涂漆前金属表面处理及涂漆工艺分技术委员会(SAC/TC 5/SC 6)

GB/T 13288的本部分规定了对GB/T 132881中的表面粗糙度比较样块的校准和表面粗糙度的触针测定法。
<br/ GB/T 13288的本部分也适用于喷射清理后、平均峰谷差在Ry5=20 μm～200 μm范围的平面钢材或复制件的表面粗糙度的测定。测量可在喷射清理表面的代表性区域进行，若不能直接在该表面测量，则可在该表面的复制件上进行测量(参见附录C)。
注: 若需要，也可用于评定其他经磨料喷射清理的基材表面粗糙度。
另一个可选的方法见ISO 8503-3。
