Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

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.

Microfluidic pumps — Symbols and performance
communication
1 Scope
This document provides symbols and defines standard datasheets for some of the most often used microfluidic
pumps, such as the peristaltic pump, pressure pump, syringe pump and diaphragm/membrane pump.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 10991 and the following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
peristaltic pump
volumetric pump in which the flow of the liquid is achieved by the cyclic deformation (expansion and
contraction) of a flexible body
[SOURCE: ISO 5681:2020, 3.2.5.5 modified — “the continuous progression of a deformation in a flexible
tube” replaced by “the cyclic deformation (expansion and contraction) of a flexible body”.]
3.2
pressure pump
volumetric pump in which the flow is achieved by the pressurization of a gas to drive a liquid into a system
[SOURCE: ISO 5681:2020, 3.2.5.1 modified — “means of the positive displacement of the liquid” replaced by
“pressurization of a gas to drive a liquid into a system”.]
3.3
syringe pump
volumetric pump in which the flow of the liquid is achieved by means of one or more single action syringe(s)
or similar container(s)
[SOURCE: IEC 60601-2-24:2012, 201.3.220, modified — “infusion” replaced by “volumetric”; “intended for
controlled infusion of liquids into the patient” replaced by “in which the flow of the liquid is achieved”; “(e.g.
where the cartridge/bag is emptied by positive pressure applied to the cartridge/bag) in which delivery
rate is indicated in volume per unit of time or units related to drug dosage” was deleted.]

3.4
diaphragm pump
membrane pump
volumetric pump in which the flow of the liquid is achieved by the deformation of a diaphragm
[SOURCE: ISO 5681:2020, 3.2.5.3, modified — "membrane pump" has been added as a preferred term.]
