Laboratory Quality Control Practice Test

Which document records traceability to standards?

User manual Safety data sheet Certificates Service ticket

Correct Answer:

Certificates

Explanation:

Records that show traceability to standards are captured in certificates. A calibration or reference-material certificate explicitly names the standard used, reports the results and their uncertainties, identifies the instrument or item calibrated, and provides the date and signatory. This creates an auditable link from your measurements back to recognized reference standards, which is essential for quality systems and regulatory compliance. Other documents serve different roles—user manuals describe how to operate equipment, safety data sheets give hazard and handling information, and service tickets document maintenance—so they do not establish the formal linkage to standards.
