CAC Technical Inspection Procedures 2

Question 1

What is the purpose of a 'witness point' in a technical inspection plan?

Accepted Answer

A designated point in the manufacturing or test process where the acceptance authority must be present before work can continue

Answer

A witness point requires the acceptance authority to observe a specific process or test before the contractor is permitted to proceed to the next step, ensuring oversight of critical activities.

Question 2

When performing a dimensional inspection using precision measurement equipment, which practice is essential to ensure measurement accuracy?

Accepted Answer

Ensuring all measurement equipment is calibrated to traceable standards and within its calibration interval

Answer

Calibration to traceable standards (e.g., NIST) within the required interval ensures measurement results are accurate, repeatable, and legally defensible.

Question 3

Which of the following best describes a 'hold point' in technical inspection procedures?

Accepted Answer

A mandatory stop in the production process that requires acceptance authority notification and approval before proceeding

Answer

A hold point mandates that work stop and the acceptance authority be notified and must approve continuation, providing stronger oversight than a witness point.

Question 4

During acceptance testing of software, what does 'regression testing' verify?

Accepted Answer

That previously passing tests still pass after changes or fixes have been made to the software

Answer

Regression testing confirms that changes to software have not broken previously verified functionality, ensuring stability throughout the development and acceptance process.

Question 5

An acceptance inspector is reviewing weld quality on a structural component. Which nondestructive testing (NDT) method is most appropriate for detecting subsurface cracks?

Accepted Answer

Ultrasonic testing

Answer

Ultrasonic testing (UT) uses high-frequency sound waves to detect internal flaws, making it the appropriate NDT method for subsurface crack detection in welds.
