Preparation of steel substrates before application of paints and related products. Analytical colorimetry method to support visual assessment of surface preparation grades Ingestion-build-47786 The purpose of this International1 Scope This document provides guidance on the usage of analytical colorimetry to support visual assessment of surface preparation grades described in ISO 85011: 2007, Clause 4. This document provides examples of applications where the use of a colorimeter or spectrophotometer can enable a quick and objective assessment of the preparation grade of the substrate. NOTE The data given in this document was obtained using the methodology described in Annex
