ISO 8655
Piston-operated volumetric apparatus
TL;DR
International standard for the metrological performance, marking, testing and conformity of piston-operated pipettes, burettes and dispensers.
ISO 8655 (eight-part series, 2022 revision) specifies measurement accuracy and precision requirements for piston-operated volumetric apparatus and the gravimetric reference procedure for verifying them. Part 6 details the gravimetric test using deionised water on a balance with stated readability.
For a GMP or ISO 17025 lab, pipette calibration to ISO 8655 is the evidence underpinning every quantitative volumetric step — without it, any analytical result that depends on pipetted volume is undefendable.
