Describe various geographical environments in terms of their atmospheric corrosivity Summarize the main factors causing atmospheric corrosion Explain how these factors are measured Examine how the safety introduced by the massive usage of deicing salts has modified the corrosivity of road environments Design a testing program to establish the corrosivity map of a given site or even a country re...

Characterization of soil corrosivity in archaeological sites is an important subject to understand the conservation conditions of archaeological bronze collections and helps conservators to prepare a conservation strategy for long term preservation of bronze objects. In this paper, a research approach is established to identify soil corrosivity in two archaeological sites and to find correlatio...

There have been several highly significant achievements in the area of alternatives for skin corrosivity testing in the last three years, most notably: (a) the validation, and subsequent endorsement, of two replacement alternative tests for skin corrosivity (the rat skin transcutaneous electrical resistance [TER] and EPISKINtrade mark human skin model assays) by the European Centre for the Vali...

background: corrosivity is one of the factors affecting the water quality. not controlling the chemical quality of water in the distribution network causes corrosion, sedimentation and economical and health damages. the aim of this study was to determine the drinking water corrosivity and sediment of kuhdasht, iran by using the corrosivity index. methods: in this study, 12 predetermined areas l...

External corrosion was identified as one of the main causes of pipeline failures worldwide. A solution that addresses the issue of detecting and quantifying corrosivity of environment for application to existing exposed pipelines has been developed. It consists of a sensing array made of an assembly of thin strips of pipeline steel and a circuit that provides a visual sensor reading to the oper...

Several factors may contribute to the structural failure of cast/ductile iron water mains, the most important of which is considered to be corrosion. The ANSI/AWWA C105/A21.5–99 10-point scoring (10-P) method is the most common method used to predict soil corrosivity potential, which is based on soil properties. For a given soil sample, each soil property is evaluated for its contribution towar...

National and international regulations require that chemicals must be properly classified, labeled, packaged, and transported based on their ability to damage or destroy tissue, e.g., skin. Traditionally, skin corrosion assessments were based on tests involving topical application of test substances to the skin of rabbits. In the present work, an in vitro skin corrosion test based on the use of...
