What is a calibration standard?

• A. A device that has known values used to calibrate other measuring devices
• B. A document that lists procedures for instrument calibration
• C. An instrument that allows for immediate results
• D. A range of acceptable values for measurements

Answer: (A)

A calibration standard is defined as a device or material that possesses known values of a particular quantity used to calibrate other measuring devices. These known values serve as a reference point, ensuring that the measurement instruments are providing accurate and reliable results. Calibration standards are crucial in a calibration process because they help establish a baseline against which the performance of other instruments can be assessed. For example, if you are calibrating a thermometer, you would use a calibration standard that has a precise known temperature to ensure that the thermometer provides accurate readings. This relationship reinforces the importance of calibration standards in maintaining measurement traceability and ensuring consistency across various measuring devices. In contrast, the other choices refer to different aspects of calibration or measurement. The document listing procedures pertains to guidelines rather than the standards themselves. An instrument that allows for immediate results does not define a calibration standard but rather describes a characteristic of a different type of measuring instrument. Lastly, a range of acceptable values for measurements relates more to accuracy specifications or tolerances rather than detailing what constitutes a calibration standard.
