ISO 8655:2022 – Pipette calibration and standards

Proper maintenance of pipettes is crucial for ensuring work quality, as their performance can degrade over time due to various factors. Regular calibration is essential to maintain accuracy and precision. ISO 8655 differs from ISO 17025, as the former focuses on calibration procedures for piston-operated volumetric apparatus (POVA), while the latter sets requirements for calibration laboratory accreditation. In this application note, Sartorius discusses ISO 8655:2022, which outlines requirements for producing and controlling POVA, including testing methods, equipment, and reporting.
