Licensing and use terms
As stated above, ISO documents, as well as any updates and/or corrections, and any intellectual property or
other rights pertaining thereto, are owned by ISO. ISO documents are licensed, not sold. This document does
not in any way operate to assign or transfer any intellectual property rights from ISO to the user. ISO
documents are protected by copyright law, database law, trademark law, unfair competition law, trade secrecy
law, and any other applicable law. Users acknowledge and agree to respect ISO’s intellectual property rights
in the ISO documents.
The use of ISO documents is subject to the terms and conditions of the applicable licence agreement.
ISO documents are provided under different licensing agreement types (“Licence Type”) allowing a non-
exclusive, non-transferable, limited, revocable right to use/access the ISO documents for one or more of the
purposes described below (“Purpose”), which may be internal or external in scope. The applicable Purpose(s)
must be agreed in the purchase order and/or in the applicable licence agreement.
a) Licence Type:
1) Single registered end-user licence (watermarked in the user’s name) for the specified Purpose. Under
this license, the user cannot share the ISO document with a third party, including on a network.
2) Network licence for the specified Purpose. The network licence can be assigned to either unnamed
concurrent end-users or named concurrent end-users within the same organization.
ii
b) Purpose:
1) Internal Purpose. Internal use only within the 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 use rights (such as for internal
meetings, internal training programmes, preparation of certification services, for 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/or in the applicable licence
agreement, and specific fees and requirements apply to each permitted use.
2) External Purpose. External use, including but not limited to:
— testing services;
— inspection services;
— certification services;
— auditing services;
— consulting services;
— conformity assessment scheme development and implementation;
— training services;
— education;
— research;
— software development and other digital platform or software-enabled digital services;
— any other services or activities conducted by the user or the user’s 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 the user’s country, any other ISO member body or an
authorized third-party distributor, including any applicable external use rights (e.g. in publications,
products, or services marketed and sold by the user/the user’s organization). Each external use must
be explicitly specified in the purchase order and/or in the applicable licence agreement, and specific
fees and requirements apply to each permitted use.
Unless users have been granted use rights according to the above provisions, they are not granted the right to
share or sublicense ISO documents inside or outside their organization for either Purpose. If users wish to
obtain additional use rights for ISO documents or their content, users can contact ISO or the ISO member body
in their country to explore possible options.
If the user or the user’s organization is granted a licence for the External Purpose of providing any of the
following services to third parties:
— testing services;
— inspection services;
ii(bis)
— certification services;
— auditing services;
— consulting services,
and if any of these five (5) services reference, rely upon, incorporate, or otherwise make use of any aspect,
requirement, provision, or any other information of any ISO document, the user or the user’s organization
agrees to verify that the third party receiving such services has obtained from the ISO member body in their
country, any other ISO member body, ISO or an authorized third-party distributor, a valid licence for its own
implementation of such ISO document or other use related to such services. This verification obligation must
be included in the applicable licence agreement obtained by the user or the user’s organization.
ISO documents must not be disclosed to third parties, and users must use them solely for the purpose specified
in the purchase order and/or applicable licensing agreement. Unauthorized disclosure or use of ISO
documents beyond the licensed purpose is prohibited and can result in legal action.
Use restrictions
Except as provided for in the applicable licence agreement and subject to a separate licence by ISO, the ISO
member body in the user’s country, any other ISO member body or an authorized third-party distributor, users
are not granted the right to:
— use ISO documents for any purpose other than the Purpose;
— grant use or access rights to ISO documents beyond the Licence Type;
— disclose ISO documents beyond the intended Purpose and/or Licence Type;
— sell, lend, lease, reproduce, distribute, import/export or otherwise commercially exploit ISO documents.
In the case of documents that are joint publications (such as ISO/IEC documents), this clause applies to
the respective joint copyright ownership;
— assign or otherwise transfer ownership of ISO documents, in whole or in part, to any third party.
Regardless of the Licence Type or Purpose for which users are granted access and use rights for ISO
documents, users are not permitted to access or use any ISO documents, in whole or in part, for any machine
learning and/or artificial intelligence and/or similar purposes, including but not limited to accessing or using
them
a) as training data for large language or similar models, or
b) for prompting or otherwise enabling artificial intelligence or similar tools to generate responses.
Such use is only permitted if expressly authorized through a specific licence agreement by the ISO member
body in the requester’s country, another ISO member body, or ISO. Requests for such authorization are
considered on a case-by-case basis to ensure compliance with intellectual property rights. Specifically, it is not
possible to 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 documents, 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 can request in writing to perform an audit, or have an audit performed by a third-party auditor,
during business hours at the user’s premises or via remote access.

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.
