Answer 1

1. Which of the following characteristics are normally considered when selecting the type of penetrant to be used in a penetrant test.
- d. All of the above
When selecting a penetrant, factors such as its removal characteristics, sensitivity level, and cost are all considered.

2. Which type of developer should not be used with a visible dye penetrant process?
- a. Dry
Dry developers are not suitable for use with visible dye penetrants as they do not effectively develop the penetrant.

3. The most significant advantage of the visible solvent removable penetrant process is?
- a. Its suitability for penetrant testing of articles with rough surfaces
visible solvent removable process is particularly advantageous for testing rough surfaces because the solvent can easily remove the penetrant.

4. Which of the following is a discontinuity that might be found in a welded fabrication?
- b. Lack of fusion
Lack of fusion is a common discontinuity in welded fabrications where the weld does not fully fuse the materials together.

5. The most important penetrant test processing time to control is
- a. Penetrant Dwell Time
Penetrant dwell time is critical as it determines how long the penetrant has to seep into any discontinuities before being developed.

6. Which of the following is a discontinuity that might be found in rolled plate?
- a. Laminations
Laminations are a type of discontinuity that can occur in rolled plates due to improper rolling conditions.

7. A penetrant which contains an emulsifier is called
- b. Water Washable
A penetrant that contains an emulsifier and can be removed with water is termed water washable.

8. A penetrant which requires a separate emulsification step prior to removal from the surface of the test piece is called?
- c. Post emulsifiable
Penetrants that need a separate emulsification step before being removed are called post emulsifiable.
