This part of ISO 8655 specifies the photometric reference measurement procedure for the determination of volume of piston-operated volumetric apparatus (POVA). The procedure is applicable to complete systems comprising the basic apparatus with a maximum nominal volume of 5 ml and all parts selected for use with the apparatus, disposable or reusable, involved in the measurement by 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 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 procedure for the determination of volume of piston-operated volumetric apparatus is given in ISO 8655-6. Alternative measurement procedures for the determination of volume are given in ISO 8655-7.
