Iso 8502-3 Pdf [2021] Jun 2026

ISO 8502-3 specifies a field method for assessing the amount of dust on steel surfaces that have been blast-cleaned or otherwise prepared prior to painting. Dust can impair coating adhesion and performance, especially in aggressive environments. The standard is widely used in protective coating industries, including marine, offshore, infrastructure, and industrial painting.

In conclusion, ISO 8502-3:2017 is an essential standard for ensuring the proper preparation of steel substrates before the application of paints and related products. The standard provides guidelines for measuring and classifying surface roughness characteristics of blast-cleaned steel substrates, which is crucial for achieving high-quality coatings and ensuring the durability and performance of coated products. iso 8502-3 pdf
