Question 1: Which ASNT document serves as the primary recommended practice for qualification and certification of NDT personnel in the US?
- SNT-TC-1A (Correct answer)
- ASME Section V
- AWS D1.1
- ASTM E1444
Correct answer: SNT-TC-1A
SNT-TC-1A is ASNT's recommended practice that provides guidelines for employer-based qualification and certification of NDT personnel.
Question 2: ASNT CP-189 differs from SNT-TC-1A primarily in that CP-189:
- Is a recommended practice only
- Sets minimum mandatory requirements for certification (Correct answer)

Question 4: ASTM E1316 is a standard that provides:
- Qualification requirements for radiographers
- Terminology for nondestructive examinations (Correct answer)
- Acceptance criteria for weld inspections
- Procedures for ultrasonic thickness measurement
Correct answer: Terminology for nondestructive examinations
ASTM E1316 is the standard terminology for nondestructive examinations, defining terms used across all NDT methods.
Question 5: Under AWS D1.1, which NDT method is required for qualifying welding procedures in structural steel?
- Only visual testing
- Any method approved by the engineer (Correct answer)
- Ultrasonic testing exclusively
- Radiographic testing exclusively
Correct answer: Any method approved by the engineer
AWS D1.1 allows any NDT method approved by the engineer of record, provided it meets the code's acceptance criteria.
