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

Which methods can be used to apply penetrant to a test piece?

1. Dipping, brushing or spraying

2. Spraying only

3. Brushing or spraying only

4. Dipping or spraying only

The correct answer is: Dipping, brushing or spraying

The methods that can be used to apply penetrant to a test piece include dipping, brushing, or spraying, which is why this answer is recognized as the correct one. Each of these methods serves as a practical application technique depending on the size, shape, and accessibility of the test piece. Dipping involves immersing the test piece in the penetrant, ensuring complete coverage, making it ideal for smaller or simpler geometries. Brushing allows for localized application, which can be useful for irregular surfaces or when working with a large test piece where only specific areas need attention. Spraying is beneficial for achieving an even coating over larger areas and can also help in reaching those spots that might be difficult to access otherwise. The other options are too restrictive because they limit the application methods. For example, suggesting only spraying lacks the versatility offered by dipping and brushing, which are also valuable techniques in different scenarios. Therefore, the comprehensive nature of the first option encompasses all available methods for applying penetrant effectively.
