Technical Inspection Procedures Flashcards

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

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

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.

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

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

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

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

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

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

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

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

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

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

Answer: Ultrasonic testing

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

What does AQL (Acceptable Quality Level) represent in the context of acceptance sampling?

Answer: The worst tolerable average proportion of defectives in a submission that is considered satisfactory for acceptance purposes

AQL defines the poorest quality level that is still considered satisfactory as a process average, setting the threshold for acceptance sampling plan design.

When an acceptance inspector identifies a major nonconformance during inspection, which action must occur before the next step in the acceptance process?

Answer: A formal Corrective Action Request (CAR) is issued and the contractor must respond with a corrective action plan

Major nonconformances require a formal CAR to document the finding, require contractor response, and ensure corrective action is tracked to closure.
