PT Level II practice questions and how to drill them

What PT practice should cover

ASNT lists the PT General exam as 50 items in 2 hours across four topics: Review PT Principles, Selection of the Appropriate PT Method, Inspection and Evaluation of Indications, and Inspection Procedures and Standards. ASNT publishes no weights for them, and PT has no before-and-after date split. The PT Level II exam guide covers the topics and the format, and the PT practice guide sets out a four-topic review plan. Use the questions here to test that plan.

Question 1: Heavy background

You are running a visible, solvent-removable inspection on a rough weld cap. After development, the whole surface shows a pink background that hides small indications. What is the most likely cause?

• A. Too much excess penetrant was removed
• B. Too little excess penetrant was removed before development
• C. The part was precleaned too well
• D. The dwell time was too short

Answer: B. Heavy background means penetrant is still sitting on the surface when the developer goes on, so the developer draws it up everywhere. The usual fix is to clean the part and repeat the process with more careful removal. A is the opposite problem: over-removal can wash penetrant out of a discontinuity and make indications weaker, not hide them. C is wrong because good cleaning helps. D would mean fewer indications, not more background.

Notice the setting in the question. A rough surface makes wiping harder, so a candidate who thinks about the part reaches B faster than one who recites the process.

Question 2: Method for speed on rough surfaces

A shop needs to inspect a large batch of threaded fittings quickly, and the surfaces are rough. Assuming the procedure leaves the choice open, which removal method fits best?

• A. Solvent-removable, wiped by hand
• B. Water-washable
• C. Post-emulsifiable, since it is always best
• D. No removal step is needed

Answer: B. Water-washable penetrant rinses off with water, which is fast for many parts and copes better with rough surfaces and threads than hand wiping. The trade-off is that an overlong or forceful rinse can wash penetrant out of shallow, open discontinuities, so rinse time and pressure need control. A is slow over a batch. C is a trap, since post-emulsifiable adds a step that is chosen when shallow discontinuities matter and the shop can hold emulsifier time steady, not as a default. D is wrong because excess penetrant must come off.

The PT exam guide has a three-part decision flow for this topic: penetrant type, removal method and remover. Run it on parts you see at work.

Question 3: Why cleaning matters

Why must a part be properly cleaned and dry before penetrant goes on?

• A. Contaminants or liquid can block the opening, so penetrant cannot enter the discontinuity
• B. A clean part cools faster
• C. Cleaning changes the penetrant's color
• D. A dry part needs no developer

Answer: A. Penetrant works by capillary action, so it has to reach the discontinuity. Oil, paint, scale or water sitting in the opening stops it entering, and the defect can go undetected. B, C and D have no basis in the process. A common follow-up in practice: say what would happen if you skipped postcleaning, which is the other end of the same sequence.

Question 4: Observation versus acceptance

You find a linear indication 2 mm long on a part. A colleague says, "On my last job anything under 3 mm was fine, so accept it." What is the sound response?

• A. Accept it, since 2 mm is under 3 mm
• B. Reject it, since all indications are rejectable
• C. Record what you see and check the acceptance criteria in the code, specification or contract your procedure names
• D. Ask the colleague to decide

Answer: C. The size limit from another job is not a substitute for the document that controls this one. Describe the indication, confirm the process conditions support interpreting it, then identify the document that supplies acceptance criteria and apply that. A and D rely on memory or a third party. B overstates: some indications are acceptable under the governing document.

The process control and indications guide covers relevant, nonrelevant and false indications and how to separate the observation from the decision.

A drill routine for PT

Run this loop after each set:

1. Write the reason first. Note the surface condition, the process step or the method you assumed, before opening the explanation.
2. Find the assumption that changed: surface, process order, method, viewing condition, indication class or document.
3. Name one condition that would change the decision. If the part were smooth machined stock instead of a rough cap, would your method choice change?
4. Explain it aloud without the choices. If you cannot, review the lesson and try again later.
5. Keep the original miss in the log so repeated errors stay visible.

If you have only two weeks, the MT and PT short plan puts the four topics on a calendar, and how liquid penetrant testing works walks the process step by step. If you are still deciding between methods, read which NDT method to certify in first.

FAQ

Are these the real PT Level II exam questions?

No. They are original practice items written to ASNT's published topics, with invented scenarios. Real exam items are confidential, and recalled items are not a safe way to study.

How many topics does the PT General exam have?

ASNT lists four topics on the examinations page, with 50 items in 2 hours. It publishes no percentage weights, so practice all four.

Is PT easier than MT?

PT has fewer topics and shorter training and experience requirements, but method selection takes real practice. Use the free check for each method to judge your own readiness.

Does the written PT exam replace the practical exam?

No. ASNT gives the computer-based General and Specific exams, and the employer handles the practical and any job-specific exams under its written practice.
