Liquid Penetrant Testing Level 2 (PT-2) Practice Exam

Which of the following is a characteristic of water washable penetrants?

1. Requires solvents for removal

2. Low sensitivity to surface conditions

3. Quick and easy to clean

4. Used primarily for high-heat applications

The correct answer is: Quick and easy to clean

Water washable penetrants are designed to be easily removed using water, which makes them particularly efficient for cleaning processes after inspection. This characteristic allows for a quick and straightforward cleanup, minimizing downtime and reducing labor intensity associated with the removal of penetrants. The ability to use water simplifies the post-inspection process, making it a preferred choice for many applications where rapid assessment is necessary. Additionally, water washable penetrants typically do not require solvents for removal, as is the case with other types of penetrants, which contributes to their convenience and user-friendliness. This characteristic enhances safety by reducing the need for the handling of potentially hazardous solvents. However, it is essential to note that their sensitivity to surface conditions can vary, and they are not specifically tailored for high-heat applications, as those often require different types of penetrants that can withstand extreme temperatures without degrading.
