An ISO 17025 calibration guarantees the traceability of your equipment to the International System of Units (SI). This traceability is the only way to be sure that your measurement results are globally comparable and true. A calibration is traceable when the performed measurement is directly linked to the respective national standard by a consistent measurement chain. Traceable calibrations mean international comparability of results obtained with a calibrated instrument.
This can be illustrated with an example from international trade: The prerequisite of international comparability is traceability to national standards. A pharmaceutical company, for example, can be sure that the composition of an infusion solution, such as a binary salt solution, is identical in every single production site worldwide if the company’s calibrated density meters give identical results.
ISO 17025 calibrations are performed by officially accredited labs. Certificates can be acquired for newly ordered instruments but also for instruments already in place, at any time.
