RAS Syndrome in Corrosion

RAS syndrome stands for redundant acronym syndrome syndrome and refers to the redundant use of one or more of the words that make up an acronym or initialism with the abbreviation itself, thus in effect repeating one or more words. Usage commentators consider such redundant acronyms poor style and an error to be avoided in writing, though they are common in speech. The term "RAS syndrome" is itself a redundant acronym, and thus is an example of self-referential humor.

From Wikipedia

I can think of several terms commonly used in corrosion, including AC current or DC current, AC current attenuation, DA assessment, SCC cracks, CSE electrode, etc. Corrosion engineers are very fond of their TLAs.
