Which statement does not apply to developers used during penetrant testing?

Developers are normally highly fluorescent
Developers may be used to enhance visibility
Developers must dissolve penetrant
Developers help retain penetrant indications

The correct answer is: Developers must dissolve penetrant

Developers used in penetrant testing serve several important functions, making various statements about their properties and uses valid. The aspect that does not apply is that developers must dissolve penetrant. In fact, developers work by adsorbing the penetrant that remains in the flaws of the material being tested, rather than dissolving it. Fluorescent developers typically enhance the visibility of the indications, especially under ultraviolet light, which aligns with how they are often formulated. Their purpose is fundamentally about retaining the penetrant indications so that they can be visualized during the inspection process. Thus, while developers can aid in enhancing the visibility of indications and do provide three key roles as described, the idea that they must dissolve penetrants does not correctly represent their function in penetrant testing.
