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.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Licensing and use terms
The ISO publications, as well as any updates and/or corrections, and any intellectual property or other rights
pertaining thereto, are owned by ISO. ISO publications are licensed, not sold. Nothing in this document shall
operate to assign or transfer any intellectual property rights from ISO to the user. The ISO publications are
protected by copyright law, database law, trademark law, unfair competition law, trade secrecy law, or any
other applicable law, as the case may be. Users acknowledge and agree to respect ISO’s intellectual property
rights in the ISO publications.
The use of ISO publications is subject to the terms and conditions of the applicable licensing agreement.
ISO publications are provided under different licensing agreement types (“License Type”) allowing a non-
exclusive, non-transferable, limited, revocable right to use/access the ISO publications for one or more of the
following purposes described below (“Purpose”), which may be internal or external in scope. The applicable
Purpose(s) must be captured in the licensing agreement.
a) License Type:
i. a single registered end-user license (watermarked in the user’s name) for the specified Purpose.
Under this license the user cannot share the ISO Publication with anyone, including on a network;

iv
ISO 5059-1:2025(en)
ii. a network license for the specified Purpose. The network license may be assigned to either unnamed
concurrent end-users or named concurrent end-users within the same organization.
b) Purpose:
i. Internal Purpose: internal use only within user’s organization, including but not limited to own
implementation (“Internal Purpose”).
The scope of permitted internal use is specified at the time of purchase or through subsequent
agreement with ISO, the ISO member body in the user’s country, any other ISO member body or an
authorized third-party distributor, including any applicable internal reproduction rights (such as
internal meetings, internal training programs, preparation of certification services, integration or
illustration in internal manuals, internal training materials, and internal guidance documents). Each
internal use must be explicitly specified in the purchase order, and specific fees and requirements will
apply to each permitted use.
ii. External Purpose: external use, including but not limited to:
— testing services
— inspection services
— certification services
— auditing services
— consulting services
— training services
— software development and other digital platform or software-enabled digital services; and
any other services or activities conducted by the user or users’ organization to third parties, whether
for commercial or non-commercial purposes (“External Purpose”).
The scope of permitted external use is specified at the time of purchase or through subsequent agreement
with ISO, the ISO member body in user’s country, any other ISO member body or an authorized third-
party distributor, including any applicable external reproduction rights (e.g. in publications, products, or
services marketed and sold by user/user’s organization). Each external use must be explicitly specified
in the purchase order, and specific fees and requirements will apply to each permitted use.
Unless users have been granted reproduction rights according to the above provisions, they are not granted
the right to share or sub-license the ISO publications in- or outside their organization for either Purpose. If
users wish to obtain additional reproduction rights for ISO publications or their content, users may contact
ISO or the ISO member body in their country to explore their options.
In case the user or the user’s organization is granted a license for the External Purpose of providing any of
the following services to third parties:
— testing services
— inspection services
— certification services
— auditing services
— consulting services
the user or user’s organization agrees to verify that the third party receiving such services has obtained
a license for its own implementation of the ISO Standard being used from the ISO member body in their
country, any other ISO member body, ISO or an authorized third-party distributor. This verification
obligation shall be included in the applicable license agreement obtained by the user or user’s organization.

v
ISO 5059-1:2025(en)
The ISO publications shall not be disclosed to third parties, and Users shall use them solely for the purpose
specified in the purchase order and/or applicable licensing agreement. Unauthorized disclosure or use of
ISO publications beyond the licensed purpose is prohibited and may result in legal action.
Use restrictions
Except as provided for in the applicable License Agreement and subject to a separate license by ISO, the ISO
member body in user’s country, any other ISO member body or an authorized third-party distributor, users
are not granted the right to:
— use the ISO Publications for any purpose other than the Purpose;
— grant use or access rights to the ISO Publications beyond the License Type;
— disclose the ISO Publications beyond the intended Purpose and/or License Type;
— sell, lend, lease, reproduce, distribute, import/export or otherwise commercially exploit ISO Publication(s).
In the case of joint standards (such as ISO/IEC standards), this clause shall apply to the respective joint
copyright ownership;
— assign or otherwise transfer ownership of the ISO Publications, in whole or in fragments, to any third party.
Regardless of the License Type or Purpose for which users are granted access and use rights for ISO
publications, users are not permitted to access or use any ISO publications, in whole or in fragments, for
any machine learning and/or artificial intelligence and/or similar purposes, including but not limited to
accessing or using them (i) as training data for large language or similar models, or (ii) for prompting or
otherwise enabling artificial intelligence or similar tools to generate responses. Such use is only permitted
if expressly authorized through a specific license agreement by the ISO member body in the requester’s
country, another ISO member body, or ISO. Requests for such authorization may be considered on a case-
by-case basis to ensure compliance with intellectual property rights. For the avoidance of doubt, you
cannot claim the benefit of copyright exception of Article 4 of the Directive (EU) 2019/790 of the European
Parliament and of the Council of 17 April 2019 on copyright and related rights in the Digital Single Market,
for the purpose of text and data mining on ISO Publications, as ISO hereby opts out of this exception.
If ISO, or the ISO member body in the user’s country, has reasonable doubt that users are not compliant with
these terms, it may request in writing to perform an audit, or have an audit performed by a third-party
auditor, during business hours at user’s premises or via remote access.
