UNE EN ISO 8655-9:2022
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 made of glass or glass and metal designed to deliver their selected 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. 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 given in ISO 8655-7.
