Some POVA require the use of exchangeable parts during typical use (e.g., disposable pipette tips). The new ISO 8655 describes the POVA and the exchangeable part as a system and requires that these exchangeable parts constitute an integral part of the POVA under test. Therefore, the calibration results are only valid for the tip type used .
Manufacturer’s acceptance specifications versus ISO 8655 acceptance specifications One of the puzzling questions about ISO 8655 is the difference between the manufacturer’s acceptance limits and acceptance specifications.
