Review of Laboratory Corrosion Tests and Standards

Abstract

ASTM Subcommittee G01.05 on Laboratory Corrosion Tests currently has nine task groups working on the development of new standards and revisions of its existing 13 standards. Revisions to existing test methods and practices often have been overlooked, resulting in confusion regarding compliance with the standards. This paper highlights the changes that have been made in existing standards over the last ten years. Problems and misconceptions associated with existing standards such as the salt spray test are discussed. Particular attention is paid to corrosion testing of electronic materials and modified salt spray testing. The former is the topic of a draft proposal in ISO, while standardization of the latter has been fragmented. The need for a coherent approach to standardization of salt spray tests is discussed. Round-robin data showing the interlaboratory reproducibility of the salt spray test are presented.

Methods to Evaluate Corrosion in Buried Steel Structures: A Review

“…This consists of a mixture of qualitative observations and quantitative measurements of soil characteristics that give rise to a global view of corrosion. In practice this turns out to be a process involving data from both field experience and laboratory research [90].…”

Correlation Studies between Outdoor Exposure and Accelerated Laboratory Corrosion Tests for Galvanic and Non-Galvanic Ceramic-Aluminum Couples

“…Laboratory experiments are dividied into following categories: electrochemical experiments, immersion tests, simulated atmospheric tests, and environmentally aggrresive tests [96]. In this study, accelerated laboratory experiments refer to humdity chamber experiments and cyclic wet/dry exposure tests conducted on galvanic and nongalvanic couples.…”

Quantitative study of exfoliation corrosion: Exfoliation of slices in humidity technique

“…Other tests involving exposure to aggressive environments have been devised, including the ASSET and MAST-MAASIS tests. In these methods, salt solutions are alternately sprayed onto the surface of the specimens and the resulting surfaces are evaluated to determine the EFC susceptibility [4][5][6][7]. The behavior of Al alloys in these accelerated environments has been correlated to long-term exposure in lessaggressive natural environments [8][9][10].…”
