DANSK DSF/FPREN ISO 8655-8 PDF

This part of ISO 8655 specifies a photometric reference measurement procedure for the determination of volume of piston-operated volumetric apparatus. The tests are applicable to complete systems comprising the basic apparatus (with a maximum nominal volume of 10 mL) and all parts selected for use with the apparatus, disposable or reusable, involved in the measurement by uptake (In) or delivery (Ex). NOTE – General requirements and definitions of terms for piston-operated volumetric apparatus are given in ISO 8655-1. For the metrological requirements, maximum permissible errors, requirements for marking and information to be provided for users for piston-operated volumetric apparatus, see ISO 8655-2 for pipettes, see ISO 8655-3 for burettes, see ISO 8655-4 for dilutors, see ISO 8655-5 for dispensers, and see ISO 8655-9 for manually operated precision laboratory syringes. The gravimetric reference measurement procedure for the determination of volume of piston-operated volumetric apparatus is given in ISO 8655-6. Alternative methods for the determination of volume are given in ISO 8655-7.
