ISO 8501-3:2006 PDF Download

ISO 8501-3:2006 is a standard that outlines the preparation grades required for steel substrates before applying paints and related products. Specifically, this standard focuses on visual assessments of surface cleanliness, with an emphasis on the preparation of welds, edges, and other areas with surface imperfections. The goal of this standard is to identify and classify imperfections on steel surfaces, such as those found on welded or fabricated surfaces, in order to ensure that they are suitable for paint application.

The standard provides specific preparation grades for steel surfaces with imperfections, based on the severity and type of imperfections found. By following the guidelines set out in ISO 8501-3:2006, manufacturers can effectively prepare their steel surfaces to meet the requirements for paint and related products, resulting in a smoother, more uniform finish.
