Question

Which of the following type of corrosion tests are usually best and more desirable?

(a) Laboratory testing

(b) Pilot-plant testing

(c) Both laboratory and pilot-plant testing

(d) Neither laboratory nor pilot-plant testing

The question was asked by my school teacher while I was bunking the class.

This intriguing question originated from Testing in division Corrosion Testing of Corrosion Engineering

Answer 1

Right choice is (b) Pilot-plant testing

For explanation I would say: Pilot-plant tests are usually best and more desirable. It duplicates the intended large-scale operation environment by using the same raw materials, concentrations, temperature, and volume of corrosive solution to the area of metal exposed.
