This part of ISO 8655 specifies — metrological requirements, — maximum permissible errors, — requirements for marking and — information to be provided for users for dispensers. It is applicable to dispensers with nominal volumes from 1 μl up to 200 ml, designed to deliver their volume (Ex). NOTE General requirements and definitions of terms for 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 will be the subject of a future Part 7 to ISO 8655. 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 dispensers, see IEC 61010-1.
