NOTE General requirements and definitions of terms of piston-operated volumetric apparatus are given in ISO 8655‑1. Conformity testing (type evaluation) of piston-operated volumetric apparatus is given in ISO 8655‑6. Alternative test methods such as photometric and titrimetric methods are given in ISO 8655‑7. For all other tests (e.g. quality assurance by the supplier, analytical and measuring equipment quality assurance by the user) see ISO 8655‑6 or alternative test methods. For safety requirements of electrically powered piston pipettes, see IEC 61010‑1.
