ME8097 NON DESTRUCTIVE TESTING AND EVALUATION

Which penetrant test processes commonly use the same penetrants?

• (a) Water washable

• (b) Water washable and solvent removable

• (c) Solvent removable and post emulsifier

• (d) None of the above

A soft aluminium test piece is to be penetrant tested. The piece has previously been sand blasted to remove tightly adhering soils. What additional surface preparation should be performed?

• (a) Etching

• (b) Solvent cleaning

• (c) Ultrasonic cleaning

• (d) Grinding

Open, shallow discontinuities are best detected by which penetrant testing method?

• (a) Solvent removable

• (b) Water washable

• (c) Post emulsifiable

• (d) None of the above

The chief advantage of using a water washable penetrant process is:

• (a) Sensitivity

• (b) Safety

• (c) Water tolerance

• (d) Economics

Dual purpose penetrants are viewed under what type of light?

• (a) White light

• (b) Black light

• (c) Both a and b

• (d) None of the above

Possible degradation of penetrant materials performance is often checked by:

• (a) Performing penetrant testing of comparator blocks using samples of new and used penetrant materials

• (b) Water tolerance test

• (c) Using a penetrant test penetrameter

• (d) Judgment of a qualified inspector during production testing

It is easier to control developer coating thickness with a soluble developer than a water suspendable one because:

• (a) Less developer can be dissolved that suspended in water

• (b) It dries more rapidly on the test piece

• (c) Evaporation deposits a thin, even coating on the test piece

• (d) All of the above

In which type of test the capillary action principle is used?

• a. Probe test

• b. Bend liquid test

• c. Dye penetrant test

• d. None of the above

Identify the type of destructive testing

• a) Radiographic test

• b) Dye penetrant test

• c) Creep test

• d) Visual testing

What is nondestructive test?

• a) Nondestructive tests are applications for detecting flaws in materials without impairing their usefulness

• b) Nondestructive tests are applications for detecting flaws that impair the use of the materials such as pressure testing

• c) Nondestructive tests are applications for detecting flaws in materials with impairing their usefulness

• d) Nondestructive tests are applications for detecting flaws that do not impair the use of the materials such as pressure testing
