DANSK DSF/FPREN ISO 8655-1 PDF

This part of ISO 8655 specifies general requirements for piston-operated volumetric apparatus (POVA). It is applicable to pipettes, burettes, dilutors, dispensers and manually operated precision laboratory syringes. It furthermore defines terms for the use of piston-operated volumetric apparatus and gives user recommendations. ISO 8655 is not applicable to medical products intended for use on humans, e.g. for medical syringes. NOTE – For the metrological requirements, maximum permissible errors, requirements for marking and information to be provided for users of 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 is given in ISO 8655-6. The photometric reference measurement procedure for the determination of volume is given in ISO 8655-8. Alternative measurement procedures for the determination of volume are described in ISO 8655-7.
