MFMET II 2026 Revision – Microfluidic devices: Interoperability requirements for dimensions, connections and initial device classification

This document details proposed revisions to ISO 22916:2022. These revisions are intended to clarify interoperability requirements without restricting existing manufacturing approaches.The main changes are as follows:• More granular dimensions for device footprints• Extended footprints for inclusion of clamping hardware• A structured framework for communicating device footprint and port positions by text• A structured framework for specifying requirements and properties of sub-regions of devices• Adjustments to the text of the scope to clearly state that this document pertains to microfluidic interconnection and not connections to/between conventional fluid handling systems.• The previously included device classifications will be expanded into a framework for specifying device operating window.• Ambiguity will be removed from the text in several places
