should it be inferred that stainless steel parts prior to a passivation treatment should or necessarily will display a fail condition with this test. A failure state can be readily observed, and the solution confirmed as functional, by using the copper sulfate solution on a piece of clean carbon steel.

toxicity are from suicidal attempts involving ingestion of copper sulphate. Individuals with a rare disorder called "Wilson's Disease" (estimated prevalence % of the population) are predisposed to accumulate copper and should not be occupationally exposed. However, in the form in which this product is sold it is relatively nontoxic.

The idea being that carbon steel is readily attack by copper sulphate solutions forming a copper deposit, while a good passivated austenitic stainless steel should not. The presents of a nitrided surface should reduce the degree of attack from copper sulphate and the presence of a white layer probably further.
