This standard BS EN ISO 8501-3:2025 - TC Tracked Changes. Preparation of steel substrates before application of paints and related products. Visual assessment of surface cleanliness is classified in these ICS categories:
25.220.10 Surface preparation
This document provides requirements to identify visible imperfections and defines three preparation grades for welds, edges and surfaces of steel to assist in achieving efficient corrosion protection. Such imperfections can be visible before or can become visible after an abrasive blast cleaning process. NOTE Although this document has been developed specifically for preparation of steel, the defined preparation grades will generally be appropriate for use when preparing other metal surfaces e.g. aluminium, castings, if agreed.
