Full title and description

IWA 23:2016 — Interoperability of microfluidic devices — Guidelines for pitch spacing dimensions and initial device classification. This International Workshop Agreement provides recommended geometrical interface dimensions (pitch/connector spacing), an initial device classification scheme and key terminology to support interoperability across microfluidic chips, connectors and related components in the microfluidics community.

Abstract

IWA 23:2016 was developed by workshop participants to harmonize connector pitch spacing dimensions, propose an initial classification of microfluidic devices and standardize related terms to improve compatibility between devices and suppliers. It serves as a guideline for designers, manufacturers and integrators to reduce integration costs and support wider commercial adoption of microfluidic technology.

Scope

The document applies to microfluidic devices and their interconnections where physical pitch spacing and connector geometry affect interoperability. It gives dimensional guidance for connector/pad pitch spacing, proposes an initial device classification to aid system integration and defines terms of relevance to help align supplier and user descriptions. It is intended as a guideline for designers, foundries, component suppliers and system integrators working with microfluidic chips and modular microfluidic components.

Key topics and requirements

• Recommended geometrical standards for pitch and connector spacing for microfluidic devices (to support mechanical and fluidic alignment).
• Initial device classification rules to group microfluidic components by interface and functionality.
• Standardized terminology for connectors, pitch, interface types and device classes to reduce ambiguity in supply chains.
• Guidance to improve interoperability between chips, sensors, actuators and passive/active modules in microfluidic assemblies.
• Considerations for measurement practice and verification of connector/pitch dimensions (recommended tolerances and reference planes).

Typical use and users

Used by microfluidic chip designers, foundries, connector and consumable manufacturers, test laboratories, integrators, research institutions and standards bodies seeking interoperable mechanical/fluidic interfaces. The guideline helps product teams reduce integration risk, component suppliers align footprints and regulators or procurement teams reference compatible device classes.

Related standards

IWA 23:2016 was withdrawn and its subject matter has been taken forward and formalized in ISO 22916:2022 — "Microfluidic devices — Interoperability requirements for dimensions, connections and initial device classification", which establishes interoperability requirements and expands the guidance into an international standard. Users should consult ISO 22916:2022 for the current normative requirements.

FAQ

Q: What is this standard?

A: IWA 23:2016 is an International Workshop Agreement that provided guidelines for pitch spacing dimensions, initial device classification and terminology for microfluidic devices to improve interoperability across components and systems.

Q: What does it cover?

A: It covers recommended geometrical connector/pitch dimensions, an initial classification scheme for microfluidic devices, and definitions of terms relevant to connectors and device interfaces; it is a guideline (not a full international standard) intended to harmonize early-stage interface practices.

Q: Who typically uses it?

A: Designers, manufacturers (foundries and connector makers), integrators, test labs and researchers in the microfluidics ecosystem use the guideline to align mechanical and fluidic interfaces and reduce integration costs and failures.

Q: Is it current or superseded?

A: IWA 23:2016 has been withdrawn and its content was revised and superseded by ISO 22916:2022; users should refer to ISO 22916:2022 for the current published requirements.

Q: Is it part of a series?

A: IWA 23 was an individual International Workshop Agreement addressing interoperability for microfluidic interfaces. Its subject matter has been incorporated into the ISO work programme (resulting in ISO 22916:2022); related ISO work items under ISO/TC 48 cover laboratory equipment and microfluidic device topics.

Q: What are the key keywords?

A: microfluidics, connector pitch, pitch spacing, interoperability, device classification, interface dimensions, microfluidic connectors.
