Which statistical process control (SPC) chart is most commonly used to monitor the average measurement of a Casper system parameter over time?
Answer: X-bar chart
The X-bar (mean) chart tracks the average value of a variable measurement over successive samples, making it ideal for monitoring continuous process parameters.
What is the purpose of a gauge repeatability and reproducibility (GR&R) study for test equipment used on Casper systems?
Answer: To evaluate whether measurement variability is acceptable relative to part tolerance
A GR&R study quantifies how much of total measurement variation comes from the gauge itself and the technicians using it, confirming whether the measurement system is reliable enough for the application.
When a Casper unit fails a final quality test, what is the correct disposition path before it can be released?
Answer: Issue a nonconformance report (NCR) and route it through corrective action
A failed unit must receive a nonconformance report (NCR) that initiates a documented corrective action process before the unit can be re-inspected and approved for release.
What is the minimum required action when a calibrated test instrument reaches its due-date for recalibration?
Answer: Remove it from service and send it for recalibration before further use
Instruments must be removed from service when their calibration due date is reached to ensure all subsequent measurements are traceable and accurate.
In a Casper quality record, what information must a corrective action entry include at minimum?
Answer: Problem description, root cause, corrective action taken, and verification of effectiveness
A complete corrective action entry must capture the problem, its root cause, the actions taken to resolve it, and evidence that the fix was verified as effective.
Which sampling plan standard is most widely referenced when performing attribute inspections on incoming Casper components in the US?
Answer: ANSI/ASQ Z1.4
ANSI/ASQ Z1.4 is the US standard for attribute sampling plans used in acceptance testing of incoming materials and components.
