- 17.060 Measurement of volume, mass, density, viscosity
This part of ISO 8655 specifies
metrological requirements,
maximum permissible errors,
requirements for marking and
information to be provided for users,
for air-displacement (type A) and positive displacement (type D) single-channel and multi-channel pipettes, complete with their selected tip(s) and any other essential, consumable parts, designed to deliver the selected volume (Ex).
General requirements and definitions of terms for piston-operated volumetric apparatus are given in ISO 8655-1. The gravimetric reference measurement procedure for the determination of volume is given in ISO 8655-6. The photometric reference measurement procedure for the determination of volume is given in ISO 8655-8. Alternative methods for the determination of volume are described in ISO 8655-7. For safety requirements of electrically powered pipettes, see regional or national safety standards.
