Interlaboratory collaborations
Understanding the variability of materials, equipment, and environments is essential to advancing corrosion performance. This can be done through round robin testing, where the same material, equipment, or process is used to validate methods or determine the range of variation, or through field experiments where the same material is used in different environments to assess differences. Both kinds of collaboration improve the understanding of corrosion processes and help build a larger dataset.
“International Round-Robin on Stress Corrosion Crack Initiation of Alloy 600 Material in Pressurized Water Reactor Primary Water”
Ten laboratories in eight countries performed crack initiation testing to the same specification using the same three heats of cold worked Alloy 600.
“Modeling Electrochemical Performance of Reinforced Concrete in Natural Marine Airborne-Exposure Environments: DURACON Project,10-Year Evaluation”
Researchers in 9 countries tested reinforced concrete specimens in 12 natural test sites with chloride-laden environments over a period of 10 years to compare the effect of the different regional climates.
“Electrochemical Noise Measurements with Dummy Cells: Evaluation of a Round-Robin Test Series”
Three round robin tests on electrochemical noise were performed between 2014 and 2017 to determine the noise level and sensitivity of the instruments.
“A Comprehensive Characterization of Environmental Severity Across 25 Sites in Nine Climactic Zones. Part 1: Witness Coupon Evaluation”
Corrosion data was collected at 25 naval air stations in the United States and abroad to characterize the local environmental severity, which will help optimize aviation maintenance practices.
“Results of Galvanic Corrosion Round Robin Testing”
Six laboratories participated in round robin testing of three galvanic couples in corrosive water to check the reproducibility of the measurements.
