When sampling inspections are permitted, the inspector follows the sampling plan that has been written specifically for that part.

• A. The sampling plan written for that part
• B. The company-wide sampling plan
• C. The supplier's sampling plan
• D. No plan

Answer: (D)

When sampling inspections are permitted, the inspector uses a plan that is written specifically for that part, because each part has unique features, critical characteristics, and acceptance criteria that require tailored sampling rules. This part-specific plan sets how many items to sample, what to inspect, and how to judge pass or fail, ensuring decisions reflect how that part is produced and meets the customer’s requirements. A generic company-wide plan might not cover the part’s particular risks or tolerances, and a supplier’s plan may not align with the buyer’s specs or approval status. Having no plan would leave the inspection without defined criteria, increasing the risk of inconsistent and untraceable results.
