CORRECT ANSWERS 100% VERIFIED.
1. Which ISO standard family primarily addresses quality management and is used to
demonstrate an organization’s ability to consistently provide products that meet customer
requirements?
A. ISO 14000
B. ISO 9000
C. ISO 45001
D. ISO 27001
Answer: B
Conceptual Explanation: The ISO 9000 family focuses on quality management, whereas
ISO 14000 is for environmental management and ISO 45001 is for occupational health and
safety.
2. In metrology, what is the term used to describe the degree to which a measurement
matches the true or accepted value?
A. Precision
,B. Resolution
C. Repeatability
D. Accuracy
Answer: D
Conceptual Explanation: Accuracy refers to how close a measurement is to the true value.
Precision refers to the consistency of repeated measurements.
3. According to the 10:1 rule (Gage Maker’s Rule), the measurement instrument should be
how much more precise than the tolerance being measured?
A. 10 times
B. 5 times
C. 2 times
D. 100 times
Answer: A
Conceptual Explanation: The 10:1 rule states that the measuring instrument should be
ten times more accurate than the tolerance of the part being measured to minimize
measurement error.
4. Which tool is best suited for measuring the diameter of a shaft to an accuracy of 0.0001
inches?
A. Outside Micrometer
, B. Steel Ruler
C. Vernier Caliper
D. Dial Indicator
Answer: A
Conceptual Explanation: Outside micrometers are designed for high-precision external
measurements, often capable of reaching 0.0001 inch increments with a vernier scale.
5. In Statistical Process Control (SPC), what does a ‘Cpk’ value of less than 1.0 indicate?
A. The process is perfectly centered.
B. The process is capable of meeting specifications.
C. The process mean is equal to the target.
D. The process is not capable of meeting specifications.
Answer: D
Conceptual Explanation: A Cpk of 1.0 means the process spread is exactly equal to the
specification width. A Cpk less than 1.0 indicates the process will produce parts outside the
specification limits.
6. Which type of control chart is used for monitoring the number of defects per unit when the
sample size is constant?
A. p-chart
B. X-bar chart
