Formal recognition by an accreditation body that a calibration or testing laboratory is able to competently perform the calibrations or tests listed in the accreditation scope document
Accuracy is a qualitative indication of the ability of a measuring instrument to give responses close to the true value of the parameter being measured.
Examination typically performed on-site of a testing or calibration laboratory to evaluate its conformance to conditions and criteria for accreditation.
The best measurement capability for a particular quantity is the smallest uncertainty of measurement a laboratory can achieve within its scope of accreditation
It is the process of verifying the capability and performance of an item of measuring and test equipment by comparison to traceable measurement standards.
A calibration curve is a graphical illustration that represents the relationship between a known, accurate input and the measured output of an instrument, thereby visually depicting calibration results. Calibration curves are typically constructed by measuring a known value of a process variable, then plotting the measured value against the true value. The resultant curve can
A calibration procedure is a controlled document that provides a validated method for evaluating and verifying the essential performance characteristics, specifications, or tolerances for a model of measuring or testing equipment.
A calibration program is a process of the quality management system that includes management of the use and control of calibrated inspection, and test and measuring equipment (IM&TE), and the process of calibrating IM&TE used to determine conformance to requirements or used in supporting activities.
A calibration seal is a device, placard, or label that, when removed or tampered with, and by virtue of its design and material, clearly indicates tampering.
A calibration standard is an IM&TE item, artifact, standard reference material, or measurement transfer standard that is designated as being used only to perform calibrations of other IM&TE items.
