Overview

ISO 7001:2023/Amd 3 is an amendment to the ISO 7001 standard, titled Graphical symbols - Registered public information symbols. Developed by the International Organization for Standardization (ISO) and maintained by Technical Committee ISO/TC 145/SC 1, this amendment introduces new public information symbols. The focus is on enhancing clarity and safety in public spaces by providing universally recognizable graphical symbols. The two newly added symbols are:

• "Do not flush down a toilet"
• "Suitable to flush down a toilet"

These additions support organizations and manufacturers seeking clear, standardized communication on product packaging and in shared facilities. Standardized graphical symbols help overcome language barriers, reduce confusion, and promote environmentally responsible disposal behavior.

Key Topics

Main subjects covered in ISO 7001:2023/Amd 3 include:

• Public Information Symbols: The amendment expands the repertoire of symbols for effective public information.
• Do Not Flush Symbol (PI BP 022): Designates items that should not be disposed of in toilets, assisting in preventing blockages and reducing environmental impact.
• Suitable to Flush Symbol (PI BP 023): Indicates items that are safe to flush, supporting users in making correct disposal choices.
• Intended Users: General population, of any age, using public or shared bathroom facilities.

Benefits of using these public information symbols:

• Reduces risks of plumbing blockages and wastewater system failures
• Helps protect wastewater treatment plants from damage
• Minimizes environmental impact by directing proper disposal behavior
• Delivers clear, language-independent guidance to a diverse user base

Applications

ISO 7001:2023/Amd 3 symbols can be practically applied in various scenarios, including:

• Product Packaging: Manufacturers of wipes, sanitary products, or similar goods can use the symbols on packaging to guide appropriate disposal by end users.
• Restrooms and Public Facilities: Facility managers can display these symbols in restrooms to inform and remind the public about proper flushing behaviors.
• Hotels, Airports, and Transport Hubs: High-traffic venues benefit from consistent symbols to communicate essential disposal instructions to international guests.
• Workplaces and Educational Institutions: Promotes responsible use of sanitary facilities and helps prevent costly damage and maintenance downtime.

By adopting these standardized graphical symbols, organizations play an important role in promoting sustainability, operational efficiency, and clear public information.

Related Standards

Utilizing ISO 7001:2023/Amd 3 alongside related international standards can enhance organisational compliance and communication strategies:

• ISO 7001: The core standard for public information symbols, defining a wide range of graphical symbols for public information purposes.
• ISO/TC 145: Related technical committee overseeing the development of standardized pictograms and graphical symbols.
• Other ISO Amendments: Regular amendments to ISO 7001 ensure the catalogue of symbols remains up to date and relevant.
• Local Wastewater Disposal Regulations: Local standards or regulations regarding appropriate waste disposal may reference or complement ISO 7001 symbols for enhanced alignment.

Incorporating these public information symbols across your organization or product line demonstrates a commitment to international best practices, effective communication, and environmental responsibility. For further guidance on implementation, consult ISO 7001 and relevant national standards organizations.

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.
