Measurement Method of Corrosion for Weathering Steel Structures ISO/CD 19691

Scope

This international standard 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
Also this standard 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.
Also this standard provides a method for evaluating the type of corrosion by visual inspection of
the appearance of rust on an existing weathering steel structure.
