Measurement method of corrosion for weathering steel structures

Méthode de mesure de la corrosion des structures en acier autopatinable

Abstract / scope

This document specifies a method for measuring the corrosion loss of each part of structures using unpainted steel such as weathering steel by using the attached coupons.

This document also provides a prediction method for corrosion loss over a long period from the measurement results and a method for determining the applicability of existing and new constructing weathering steel structures.
