Overview

ISO/TS 6417:2025 - Microfluidic pumps: Symbols and performance communication defines a common language for describing microfluidic pumps. The Technical Specification provides standardized graphical symbols and a template for standard datasheets covering widely used microfluidic pump types (peristaltic, pressure, syringe and diaphragm/membrane pumps). The aim is to enable consistent comparison of pump performance and clearer communication between manufacturers, integrators and end users.

Key topics and requirements

The specification organizes pump information into a consistent datasheet structure and defines required content areas. Key technical topics include:

• Naming and schematic/symbol

  • Use of manufacturer model plus an explicit pump type (e.g., “Brand A, Model B, Peristaltic pump”).
  • Provision of a standardized pump symbol (referencing ISO/IEC graphical symbol collections).

• Technology characteristics

  • Actuation type (electrical, pneumatic, mechanical) with operating ranges.
  • Requirement of consumables (tubing, syringes, membranes) with expected lifetime and material data.
  • Wetted materials and relevant compatibility/biocompatibility information.
  • Reversible flow capability and tolerances.
  • Closed‑loop capability (control signals and feedback sensor information).
  • Operational lifetime expectations and reusability.

• General working conditions

  • Maximum pressure, self‑priming, incubator compatibility, self‑heating, sound level, certifications and back‑pressure behavior.

• Electrical, mechanical and flow characteristics

  • Power supply and EMC data; internal volume, dimensions, weight, connectors; flow rate range, stability (standard deviation), response time, open state fluidic resistance.

• Symbols referencing

  • Graphical symbols built from ISO 7000, IEC/ISO 80416 series and ISO 14617 collections.

Applications and who uses it

ISO/TS 6417:2025 is useful for:

• Pump manufacturers – to publish consistent datasheets and symbols for product catalogs.
• Microfluidic system integrators and OEMs – to compare pump options and ensure compatibility when designing lab‑on‑a‑chip, analytical or diagnostic systems.
• Laboratory equipment designers and procurement teams – to evaluate performance against standardized criteria (flow rates, pressure, materials).
• Regulatory and quality engineers – to verify documentation completeness and interoperability in medical, biotech and research settings.

Standardized pump symbols and datasheets improve purchasing decisions, system interoperability and technical communication across the microfluidics ecosystem.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

Introduction
Several microfluidic pumps are available on the market. The relevant technical information from the
datasheet will enable end-users to compare the performance of the microfluidic pumps and to choose the
best-fitted pump for their application. Without a standardized datasheet, the comparison of the performance
of different microfluidic pumps is often not possible due to the lack of similar information or divergent
definitions of similar performance characteristics.
The following groups of characteristics are defined, described and explained with examples where it is
appropriate:
— naming;
— schematic/symbol;
— technology characteristics;
— general working conditions;
— electronical characteristics;
— mechanical characteristics;
— flow characteristics.
