This standard 20/30375677 DC BS EN ISO 8655-5. Piston-operated volumetric apparatus is classified in these ICS categories:
- 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 dispensers. It applies to dispensers with nominal volumes from 1 μl up to 200 ml, designed to deliver their 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 dispensers, see regional or national safety standards.
