calibration and testing laboratories


The implementation of ISO/IEC 17025: 2017 "General Requirements for the Competence of
Calibration and Testing Laboratories" is an important step in establishing the requirements for deciding whether to conform to a specification or standard, taking into account the requirements of
many international documents containing requirements for equipment and techniques for testing
and measurement, and the definition risks of making a certain decision on conformity assessment.
This edition of the standard proposes to standardize and evaluate the accuracy of a measurement
result, not only for measurement uncertainty, but also for other indicators in assessing the
conformity of equipment and testing and measurement techniques. An important factor in the
implementation of the standard is the development of criteria related to decision rules and claims
for the compliance of resources and processes related to personnel, contract analysis and reports.
But in addition to criteria-based assessment, it is also important to carry out metrological
confirmation of the measuring equipment used in order to obtain reliable measurement results in the
assessment of product conformity. Evaluation of metrological confirmation of the measuring
equipment confirms its compliance with the given measuring task. To perform this task properly, it
is necessary to have the appropriate measuring technique. When carrying out measurements
according to the indicated methods, it is important to strictly observe the requirements contained in
the measuring equipment, the conditions of carrying out, the sequence of measuring operations and
the requirements for specialists. Fulfillment of these requirements allows obtaining a reliable result
with the required accuracy and making an informed decision taking into account the level of risk.
