ISO 8503-5:2017描述了测量ISO 8504-2中给出的任何喷砂清理程序产生的表面轮廓的现场方法。该方法使用复制胶带和合适的量规,在喷涂油漆或其他保护涂层之前,现场测量表面粗糙度。
该方法适用于给定等级(或厚度)的复制胶带的轮廓高度范围内。目前可用的商业等级允许测量20μm至115μm的平均峰谷剖面。该方法适用于使用研磨剂清洁的表面。
ISO 8503-5:2017 describes a field method for measuring the surface profile produced by any of the abrasive blast-cleaning procedures given in ISO 8504-2. The method uses replica tape and a suitable gauge for measuring, on site, the roughness of a surface before the application of paint or another protective coating.
The method is applicable within the range of profile heights cited for a given grade (or thickness) of replica tape. The commercial grades currently available permit measurement of average peak-to-valley profiles of 20 μm to 115 μm. The method is valid for surfaces that have been cleaned with abrasives.
