AIT Quality Standards 4 — Questions and Answers
Question 1: What does ISO 9001 primarily provide to organizations?
- A government mandate for safety inspections
- A framework for establishing and maintaining a quality management system (Correct answer)
- A financial auditing standard
- A technical specification for product dimensions
Correct answer: A framework for establishing and maintaining a quality management system
ISO 9001 sets out the criteria for a quality management system based on principles including customer focus, process approach, and continual improvement.
Question 2: When is it appropriate for an apprentice to accept work that does not meet specifications 'as-is'?
- When the deviation is very small
- When the supervisor verbally says it is okay
- Only after a formal nonconformance review and documented disposition approval (Correct answer)
- Whenever the schedule is tight
Correct answer: Only after a formal nonconformance review and documented disposition approval
Accepting nonconforming work requires a formal engineering or quality review, documented disposition, and authorized sign-off—verbal approval is insufficient.
Question 3: Calibration of measuring tools is necessary primarily to:
- Keep tools looking new and professional
- Ensure measurements are accurate and traceable to a recognized standard (Correct answer)
- Satisfy union contract requirements
- Reduce the number of tools needed on a job site
Correct answer: Ensure measurements are accurate and traceable to a recognized standard
Calibration verifies that measuring instruments produce accurate results traceable to national or international measurement standards.
Question 4: A 'specification' in trade work is BEST defined as:
- An informal agreement between workers about how to do a task
- A documented requirement that a product, material, or process must conform to (Correct answer)
- A suggestion provided by the foreman
- A cost estimate for the project
Correct answer: A documented requirement that a product, material, or process must conform to
A specification is a formal, documented statement of requirements—including dimensions, materials, and performance criteria—that work must meet.
Question 5: First article inspection (FAI) is conducted to:
- Inspect the last item produced in a run to ensure consistency
- Verify that the first production piece meets all engineering and quality requirements before full production begins (Correct answer)
- Check new employees' first day of work quality
- Audit a supplier's facility before awarding a contract
Correct answer: Verify that the first production piece meets all engineering and quality requirements before full production begins
FAI confirms that the production process, tooling, and materials can produce a part that fully conforms to specifications before committing to full production.
Question 6: Which of the following is an example of a 'preventive action' in quality management?
- Reworking a batch of defective parts
- Scrapping nonconforming material
- Updating a procedure to eliminate the root cause of a potential defect before it occurs (Correct answer)
- Issuing a customer credit for a delivered defect
Correct answer: Updating a procedure to eliminate the root cause of a potential defect before it occurs
Preventive action addresses potential causes of nonconformity before they result in actual defects, distinguishing it from corrective action which responds to defects that already occurred.
Question 7: On a control chart, data points consistently near one side of the centerline but still within control limits are called:
- Random variation
- A run or trend — a signal of special cause variation (Correct answer)
- Normal operating range indicators
- Acceptable process performance
Correct answer: A run or trend — a signal of special cause variation
A run of points on one side of the centerline is a non-random pattern indicating special cause variation, even if points remain within control limits.
