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

Introduction
This document specifies general requirements that are relevant to assistive products for tissue
integrity (APTI) in the lying position in different application environments such as hospitals, home care,
and institutions. Some of the devices can be used/reused in more than one application environment.
This means that different requirements and test methods can apply to the same Assistive Products
for Tissue Integrity (APTI), depending on the application environment. For an APTI to conform with
this document, all relevant clauses need to be fulfilled, depending on the type of APTI. For example,
some APTI do not include electrical components; therefore, the clauses related to electrical components
might not be relevant.
APTI play a very important role in the prevention and treatment of pressure injuries. Another important
role in the prevention and treatment of pressure injury is the clinical practice and the clinical evaluation.
Guidance can be found in the NPUAP/EPUAP/PPPIA Guidelines, "Prevention and Treatment of Pressure
Ulcers: Clinical Practice Guideline,” from 2014.
Surfaces applied on operating theatre tables can also impact in the process of patient management
and may need to be taken into consideration. It should be recognized however, patient stability and
specialist equipment used during an operation often create conflicting priorities to those of an APTI.
Using this document, clinicians and manufacturers should consider the impact of other items (including
additional APTI) used in conjunction with an APTI on tissue integrity and safety.
This document only covers general requirements to ensure safety of users. However, the intention is to
develop a series of standards to cover the broad range of issues related to the APTI.

4 General requirements and safety
4.1 General requirements
This document describes the minimum requirements and necessary APTI development activities to be
met by manufacturer(s) or distributor(s) of an APTI to ensure safety and conformity with applicable
standards. Further guidance around medical device development, manufacturing and management can
be found in ISO 13485.
An APTI is a medical device and like any other medical devices it shall be designed, manufactured and
promoted for the appropriate use. Many application environments, types of caregivers and people sizes,
shapes and capabilities exist. These need to be considered during the development, manufacturing and
promotion of an APTI.
NOTE An example of the methodology for development, manufacturing and promotion of an APTI is
given in A.1.
4.2 Intended use
4.2.1 General requirements
As part of this document, manufacturers shall develop an intended use statement for their APTI. This
should include the application environment, the appropriate patient population (based on patient risk),
and general medical claims (such as claims to reduce the risk of pressure injuries).
The intended use should be given proper consideration throughout the development of an APTI and
considered during risk evaluation.
4.2.2 Consideration regarding intended use
Defining the intended use of an APTI will help with identifying boundaries, thereby guiding users
through the selection and usage of an APTI, and developers through the development cycle. The
ISO 20342-1:2019(E)
objective is not to limit the use of an APTI, but to make sure the context in which the APTI is supposed
to be used is well defined and understood.
4.2.3 Intended use statement
4.2.3.1 Claims
To define better the intended use, it is key to identify what the APTI will do from a clinical standpoint.
These are called claims. These help to position the clinical value of the APTI.
Ultimately, claims related to intended use statements shall be substantiated and supported by evidence;
either a specific test or a clinical evaluation showing the claimed outcome is provided by the APTI.
NOTE There are some new standards planned to be developed to support the claims.
4.2.3.2 APTI description
Once claims are defined, the next step is to provide a description of the support surface. This description
will enhance the understanding of the physical characteristics of the APTI.
EXAMPLE The manufacturer could define the overall dimension of the APTI, which would help in the
selection process as it relates to the pairing of an APTI to a bed and/or medical bed.
4.2.3.3 Users and application environments
In addition to the manufacturers claims and the APTI description, the manufacturer shall also define
the APTI users and the application environment(s) in which the APTI can be used.
User definition will at a minimum define both the type of caregivers and persons who can use the APTI.
Comprehensive APTI and targeted user descriptions will assist with the selection of an appropriate APTI.
Maximum load shall be declared by the manufacturer. It shall be included in the instructions for use
and in the marking of the APTI.
Maximum and minimum user weight shall be declared by the manufacturer and then be included in the
instructions for use and be labelled on the APTI.
Clearly defining the environment(s) will help provide guidance on where to use the APTI. Multiple
application environments exist, such as acute care, long-term care, home care etc. This becomes
relevant to ensure the appropriate risk mitigation strategy is applied.
If an APTI has limits to suitable application environments, these shall be clearly stated in the instruction
for use. The application environments might modify the application of requirements.
Consideration should also be given to contraindications for an APTI, thereby providing caregivers and
users with clear indications of potentially hazardous situations.
4.3 APTI risk management
Manufacturers shall address potential APTI risks (e.g. using ISO 14971). ISO 14971 provides a methodology
and a process for manufactur
