This part of ISO 8655 specifies - metrological requirements, - maximum permissible errors, - requirements for marking and - information to be provided for users, for manually operated precision laboratory syringes. It applies to syringes with nominal volumes up to 200 ml, designed to deliver their volume (Ex). Manually operated precision laboratory syringes are instruments used for delivering liquids and gases. The barrel is typically made of glass and the plunger and the needle are typically made of metal. 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. A photometric reference measurement procedure for the determination of is given in ISO 8655-8. Alternative methods for the determination of volume are described in ISO 8655-7.

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.
