ISO 8655-2:2022 PDF Download

The ISO 8655-2:2022 standard offers a list of requirements for piston-operated volumetric instruments, with a concentration on pipettes. The standard specifies numerous metrological standards, the largest errors that can be made, marking criteria, and information that users should be given.

Both positive displacement (type D) and air displacement (type A), single-channel or multi-channel pipettes, are covered by the standard. These pipettes must be used with the appropriate tip(s) and any additional necessary consumable parts since they are made to deliver a specific volume (Ex).

The pipettes must adhere to the essential standards of accuracy and precision, and ISO 8655-2 achieves this by establishing the necessary metrological requirements and maximum permitted mistakes. The standards for labeling, which aids with pipette identification and gives users important information, are also covered by the standard.
