Definition - What does Breakpoint mean?

A breakpoint refers to the breakpoint frequency of a given metallic substance, which are the scientifically determined range of values that are used to evaluate a coating's performance and detect coating delamination.

Corrosionpedia explains Breakpoint

A breakpoint (or breakpoint frequency) is measured in Hertz. It is used in combination with a minimum of frequency calculations to generate corrosion mitigation methods. This helps to determine when a coating will fail even with minimal short-term test data. This prediction is characterized by the evaluation of water uptake, delamination and disbonded area.
