Overview

EN ISO 23402-1:2026, issued by CEN, defines the general requirements and test methods for portable dental equipment used in non-permanent healthcare environments. This standard sets out essential criteria for devices intended to be transported and operated outside permanent dental clinics, including temporary field clinics, outreach programs, and other non-traditional healthcare settings. Adhering to EN ISO 23402-1:2026 ensures portable dental units, patient chairs, operator stools, lights, suction equipment, air compressors, and related devices are safe, reliable, and suitable for versatile deployment where fixed installations are not feasible.

Key Topics

• Scope of Application

  • Applies exclusively to portable dental equipment designed for disassembly, folding, or packaging for human transport.
  • Does not cover stationary dental devices, mobile dental clinics (vehicular/shelter-based), wearable devices (headlamps, loupes), or equipment not intended for portable, non-permanent healthcare environments.

• Classification

  • Equipment is classified by electrical operation, intended use environment (indoor vs. outdoor), utility supply type (external vs. self-contained), and transport exposure (limited or rugged).
  • Safety and performance depend on matching equipment design to its classification, particularly regarding exposure during transport and use.

• General and Transport Requirements

  • Specifies maximum modular weight and size for ease of manual transport.
  • Requires design for ruggedness, including resistance to impact, drop, vibration, and ingress of dust or liquids (IP protection) per IEC 60529.
  • Equipment must be simple to assemble/disassemble to ensure efficiency and safety during rapid deployment.

• Operational and Safety Requirements

  • Mandates usability engineering, cleaning and disinfection capability, and operational reliability under a wide range of environmental conditions.
  • Addresses instruction durability and clarity, proper marking on both equipment and packaging, and conformance with referenced standards for medical electrical safety.

Applications

EN ISO 23402-1:2026 adds value by enabling:

• Military and Humanitarian Dental Care: Portable dental equipment is essential for providing urgent dental services in field hospitals, disaster response zones, and remote areas.
• Public Health and Outreach Clinics: Supports dental programs for schools, elderly homes, correctional facilities, and underserved communities.
• Home and Long-Term Care: Makes it feasible for clinicians to offer high-quality dental care at patient residences or within long-term care institutions.
• Academic and Research Activities: Facilitates off-site educational workshops and research programs requiring flexible, robust dental setups.

By following this standard, manufacturers, healthcare organizations, and procurement authorities can be confident that equipment will perform safely and effectively in dynamic, challenging environments.

Related Standards

EN ISO 23402-1:2026 references and is harmonized with several key international standards, including:

• IEC 60601-1: General requirements for basic safety and essential performance of medical electrical equipment.
• IEC 60529: Degrees of protection provided by enclosures (IP code).
• ISO 4180: Testing transport packages for performance.
• ISO 21530: Chemical resistance for dental equipment surfaces.
• IEC 62366-1: Usability engineering in medical devices.
• IEC 80601-2-60: Particular safety requirements for dental equipment.
• ISO 9687: Graphical symbols for dental equipment.
• ISO 15223-1: Symbols for information provided by manufacturers on medical devices.

These standards ensure a consistent, high-quality approach to safety, usability, and durability in portable dental equipment across different healthcare settings.

Introduction
Transportable dental equipment is used by dental professionals to provide care to patients in a variety of
settings. Because the intended use applications and intended means for transporting such equipment vary
considerably, a wide variety of transportable dental equipment is commercially available. For example,
certain transportable equipment is designed and constructed to be carried or rolled on its own wheels
between rooms within a healthcare facility, while other transportable dental equipment is made to be folded
and packed to carry over terrain which can be rugged and used in transient dental care settings which can
have only limited shelter and utility services.
Transportable equipment that can be moved from one location to another while being carried by one or
more persons is referred to as portable equipment. The term "portable equipment" applies to equipment
that can be carried from room to room in a given facility or to remote parts of the world. This document
focuses on portable dental equipment which is specifically designed and constructed to be transported
between non-clinical environments and used by dental professionals to provide dental care in such settings,
including temporary field clinics.
Such portable dental equipment for use in non-permanent healthcare environments enables dental
professionals to provide a high standard of care to patients who do not have access to, or are not able
to, travel to traditional health care facilities. Settings in which this equipment is commonly used include
military field environments, humanitarian aid field clinics, public health outreach clinics, patient residences,
long-term care facilities, prisons, schools and workplaces.
A number of trends in health care have driven increased utilization of portable dental equipment in non-
permanent healthcare environments. Military forces use portable dental equipment in support of mobilized
forces or for humanitarian outreach. A variety of government and non-government organizations are
increasingly providing humanitarian dental care to underserved populations and populations affected
by disasters. Civilian health care workers are also increasingly providing dental services to a growing
population who are simply unable to visit traditional dental clinics due to age, disability or income. Academic
and research bodies regularly conduct dental education programmes (e.g. dentistry, dental hygiene and
dental assisting), particularly at external/off-site locations.
The transport and end-use conditions for portable dental equipment used in non-permanent healthcare
environments drive certain unique requirements which generally do not apply to portable, mobile or
stationary dental equipment used in traditional dental clinics or hospitals. Because portable equipment
used in non-permanent healthcare environments is intended to be moved between venues, and in some
cases carried over rugged terrain or in inclement conditions, it needs to be designed and constructed to
be safely transported by humans without damage, be efficiently assembled and disassembled, and deliver
reliable service at the point of use. Special consideration is given to the austerity of the environment in which
the equipment can be used and the availability and quality of utility supplies (e.g. electrical power, water,
compressed air). In order for the equipment to be sufficiently portable and capable of operating in extreme
conditions, certain requirements for dental equipment intended for use in traditional clinical settings can be
impractical and should be reconsidered for portable dental equipment for use in non-permanent healthcare
environments. There can also be unique safety and infection control concerns to consider.
The ISO 23402 series aims to standardize requirements for portable dental equipment for use in non-
permanent healthcare environments.
