DESCRIPTION
This standard 20/30375671 DC BS EN ISO 8655-2. Piston-operated volumetric apparatus is classified in these ICS categories:
  • 17.060 Measurement of volume, mass, density, viscosity

This part of ISO 8655 specifies

  1. metrological requirements,

  2. maximum permissible errors,

  3. requirements for marking and

  4. 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).

NOTE

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.
