Gravimetric calibration and testing of piston-operated volumetric apparatus (POVA) according to part 6 and 7 of the ISO 8655:2022

Reliable and reproducible liquid handling results depend crucially on the regular test and calibration of the instruments. The globally most accepted International Standardization Organization (ISO) standard that details requirements for producing and in-use control of piston-operated volumetric apparatus (POVA) is the ISO 8655. In this whitepaper, Sartorius discusses the requirements for gravimetric calibration and testing of piston-operated volumetric apparatus (POVA) according to part 6 and part 7 of the ISO 8655 revised in 2022. The paper presents the differences between calibration and testing according to chapters 6 and 7, and describes the testing method as well as the testing environment, testing equipment, and reporting requirements.
