Question 1

Which ISO standard specifically governs the competence of testing and calibration laboratories in the US?

Accepted Answer

ISO/IEC 17025

Answer

ISO/IEC 17025 is the international standard that specifies requirements for the competence, impartiality, and consistent operation of calibration and testing laboratories.

Question 2

What is the primary purpose of a calibration certificate?

Accepted Answer

To document measurement results and traceability to national standards

Answer

A calibration certificate documents the measurement results, uncertainty values, and traceability chain linking the calibrated instrument to national or international measurement standards.

Question 3

What does 'traceability' mean in the context of calibration documentation?

Accepted Answer

An unbroken chain of comparisons to national or international standards

Answer

Metrological traceability is an unbroken chain of calibrations, each contributing to measurement uncertainty, linking results to recognized measurement standards such as NIST.

Question 4

How often should calibration records be reviewed according to best quality management practices?

Accepted Answer

At defined, regular intervals as specified in the quality management system

Answer

Quality management systems require calibration records to be reviewed at defined intervals to ensure ongoing compliance and identify trends or out-of-tolerance conditions.

Question 5

What action must be taken when an instrument is found to be out of tolerance during calibration?

Accepted Answer

Initiate a nonconformance report and assess the impact on previous measurements

Answer

An out-of-tolerance finding requires a nonconformance report and a risk assessment to determine if previously made measurements may have been affected.
