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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
This International Standard applies to hand-held aerosol drug delivery devices (ADDD) intended to administer
medication to humans. To avoid unnecessarily restricting innovation, given the broad variation in device
designs, this International Standard addresses the more general design/labelling requirements rather than
specific physical and prescriptive design requirements. However, this International Standard does require the
elaboration of a device functionality profile (DFP) specific to the ADDD in question. This International Standard
also addresses ADDD design requirements from both the user interface and safety perspectives.
An ADDD is used as part of a system consisting of the ADDD, the container, the medication and the labelling,
including the instructions for use. Therefore, design verification of the ADDD includes a final system
verification test conducted in accordance with the instructions for use.
From a regulatory perspective, the ADDD system may be reviewed and approved as part of a drug product
(combination of ADDD and medication) or as a device by itself. For the purposes of this International
Standard, such regulatory distinctions do not alter the intent of the design verification process described
herein. As an example, in the European Union (EU), if an ADDD is placed on the market in such a way that
the ADDD and the medication form a single integral product (i.e. the system) that is intended exclusively for
use in the given combination and which is not refillable, that single product shall be governed by Directive
2001/83/EEC. However, the relevant essential requirements of Annex I of the Medical Device Directive
(93/42/EEC) shall apply as far as safety and performance-related ADDD features are concerned, which is the
specific objective of this design verification standard.
Regardless of the distinctions (“drug” or “device,” pre-filled or refillable), it is recognised that ADDD design
verification is an important component of the overall validation process. Moreover, design verification is
iterative, to be conducted at various phases throughout the ADDD’s development and subsequent ADDD
post-approval modifications. In all instances, design verification is conducted using the phase-appropriate
instructions for use. It is understood that in the early phases of ADDD development an appropriate subset of
the requirements contained herein might apply, but that all of the requirements will be satisfied as part of the
final design verification exercise. Furthermore, design verification should be considered a minimum
requirement for the safe and effective use of the ADDD, and in many instances additional testing may be
appropriate as indicated by a risk assessment that shall also be conducted.
This International Standard introduces the requirement for developers and/or manufacturers to create a device
functionality profile (DFP) for a given ADDD based on the ISO Standard for device risk assessment (as a part
of ISO 14971). The device functionality profile defines the parameters and tolerance intervals used to verify
the ADDD's ability to meet the manufacturer's design specifications during in-use conditions and following
environmental and electromechanical extreme use conditions. This International Standard also includes a
system verification test conducted at standard atmosphere and nominal flow rate as a simple bridge between
the device design and the patient interface.
The purpose of this International Standard is to ensure a method and guide for independent testing of the
repeatability and reproducibility of ADDD functionality that verifies compliance with its design specification.
The design verification process may include use of applicable regulatory agency requirements and/or test
methods. The sampling plans for this International Standard are intended to verify the design at a high
confidence level. They do not replace the more general manufacturing quality systems, including lot release,
which appear in standards on quality systems (e.g. the ISO 9000 series or ISO 13485).
Figure 1 illustrates the process this International Standard advises to use in order to assess and verify
whether a design meets the determined DFP.

Figure 1 — ADDD design verification process
This International Standard specifically addresses the most basic elements regarding the safe and effective
use of ADDD in humans. It does not define the pharmaceutical or clinical performance of an ADDD. Any
labelling indicating ADDD use to deliver medication to specific regions of the respiratory tract falls under the
authority of national governments or regional agencies regulating the manufacture and marketing of medical
devices and pharmaceutical products. In some countries national regulations exist, and their requirements can
supersede or complement this International Standard.
For a given manufacturer, existing marketed products and those currently under development might not fulfil
some of the requirements. However, manufacturers should comply with this International Standard when
improving the functional design of existing ADDDs or developing new ADDDs to obtain an even higher level of
quality.
Annex A describes the reasoning for establishing the various requirements in this International Standard.

INTERNATIONAL STANDARD ISO 20072:2009(E)

Aerosol drug delivery device design verification —
Requirements and test methods
1 Scope
This International Standard applies to the design, labelling, instructions for use and testing requirements for
hand-held single- and multi-use aerosol drug delivery devices (ADDDs) intended to deliver a metered or pre-
metered aerosolized medication to or by means of the human respiratory tract (including nasal, oral, tracheal,
bronchial and alveolar sites). This International Standard applies to both refillable and disposable devices
intended for personal use.
This International Standard is intended for device design verification and not for drug product quality
assessment. The objective of this International Standard is to verify, by laboratory (in-vitro) testing, that the
ADDD design consistently meets the manufacturer's design specification by satisfying a device functionality
profile and system verification test both of which are determined from a risk assessment and evaluated in
accordance with the instructions for use.
This International Standard excludes continuous or semi-continuous aerosolization devices covered in
ISO 27427, aerosolization devices which do not emit active pharmaceutical ingredient (API), general purpose
aerosolization devices (for use with ventilators) and atomizers.
This International Standard does not apply to manufacturers of single parts or components of the ADDDs [e.g.
(spray) pumps, valves, containers, etc.].
NOTE There might be times when a device falls under the scope of this International Standard and that of
ISO 27427. The committee envisions that the intended use of the product and the risk assessment of the device will derive
which International Standard the manufacturer chooses for design verification of the ADDD. This International Standard
outlines the process by which ADDD design verification is to be performed in conjunction with a risk-based device
functionality profile of the ADDD with either the medication, a placebo or a representative medication. ISO 27427 outlines
the process by which the characterization of the aerodynamic aerosol performance of a nebulizing system for use with a
non-specific class of active pharmaceutical ingredient(s) is made.
