CAC Quality Assurance and Inspection Flashcards

What is the role of a Certificate of Conformance (CoC) in acceptance processes?

Answer: It is a supplier's written declaration that products meet specified requirements

A CoC is a supplier-issued document declaring that delivered goods meet all applicable contractual and specification requirements.

In statistical process control (SPC), what does a control chart primarily help an acceptance professional determine?

Answer: Whether a production process is stable and within acceptable variation limits

Control charts track process variation over time and signal when a process is trending out of control before defects are produced.

Which sampling method selects inspection lots by dividing the population into groups and randomly sampling from each group?

Answer: Stratified sampling

Stratified sampling divides the population into homogeneous subgroups (strata) and draws random samples from each, improving representativeness.

What is a Corrective Action Request (CAR) used for in quality assurance?

Answer: Formally requiring a supplier or process owner to investigate and eliminate the root cause of a nonconformance

A CAR formally initiates root cause analysis and corrective action to prevent recurrence of a defect or quality escape.

During receiving inspection, a CAC professional finds that actual delivered quantities differ from the packing list. What should be documented?

Answer: A discrepancy report noting the overage or shortage and notifying procurement

Any quantity discrepancy must be formally documented and communicated to procurement to resolve billing, scheduling, and contractual obligations.

What does 'lot traceability' enable in an acceptance and quality system?

Answer: Tracking materials and products through each stage of production and delivery using unique lot identifiers

Lot traceability links materials, processes, and finished products so that any quality issue can be traced to its source and scope contained.
