ISO 8655, dealing with the use and calibration of pipettes, was revised quite extensively in 2022. The previous revision 8655:2002 is from 2002, so it was probably time for an update.
ISO 8655:2022
ISO 8655 is a very detailed set of standards, methods and controls that a pipette calibration provider should follow to achieve to ensure reliable calibrations.
ISO 17025 accreditation says nothing about how to perform pipette calibrations, but ISO 8655:2022 does.
The reference method is still described in part 6, but where the old standard stated that it is up to users to find alternative methods, for example for on-site service, part 7 now states alternative methods as part 7 and part 7 A.2. Part 7 can be used for annual on-site calibration and part 7 A.2 for routine checks.
