适用范围：This part of ISO 8655 specifies — metrological requirements, — maximum permissible errors, — requirements for marking and — information to be provided for users, for dilutors with a sample uptake capacity (In) from 5 μl to 10 ml and a diluent capacity (Ex) from 50 μl to 100 ml. They are designed to deliver the sample and diluent together in measured proportion and measured volume. 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 piston dilutors, see IEC 61010-1.
