Monitoring Environmental Tests by Coulometric Reduction of Metallic Control Samples

CODEN: JTEVAB

Abstract

This paper describes a standard procedure for using constant-current electrolytic reduction (“coulometric reduction”) to determine the relative buildup of corrosion and tarnish films on control coupons from environmental tests, and discusses the types of results and correlations that may be expected. Examples of the applications of this proposed ASTM standard method will be presented for two types of environmental exposure: the mixed flowing gas test and the humid sulfur vapor (“flowers-of-sulfur”) test.
