Calibration in Measurement Technology Quiz

Study Notes

Calibration and Metrology

The National Institute of Standards and Technology (NIST) is responsible for maintaining primary standards of measurement in the United States.
The purpose of establishing traceability in calibration is to ensure that measurements are consistent with national standards.
The International Organization for Standardization (ISO) 17025 and the American National Standards Institute (ANSI) Z540-1 call for an effective metrology system and formal, periodic, and documented calibration of all measuring instruments.
Calibration may be required for an instrument when it is first received, after repair or maintenance, when it is moved to a new location, or when it is used in a new application.
Calibration in measurement technology and metrology is the process of comparing a device's measurements with a reference standard to ensure accuracy and consistency.
The main purpose of calibration is to ensure that measurements are accurate and consistent with national standards.
The formal definition of calibration according to the International Bureau of Weights and Measures (BIPM) is "the set of operations that establish, under specified conditions, the relationship between values indicated by a measuring instrument or measuring system and the corresponding values of a quantity."
The purpose of calibration is to ensure that measurements are accurate and reliable, and to provide a basis for traceability to national standards.
The recommended calibration interval according to ISO 17025 is dependent on the type of instrument, usage, and environmental conditions.
The accuracy ratio required for a completely correct calibration is 4:1, where the uncertainty of the reference standard is one-fourth of the uncertainty of the device being calibrated.
Reducing the accuracy of the device being calibrated is not a purpose of calibration; instead, calibration aims to ensure that the device's measurements are accurate and consistent with national standards.
