Medical vehicles and their equipment - Road ambulances

This European Standard specifies requirements for the design, testing, performance and equipping of road ambulances used for the transport, monitoring, treatment and care of patients. It contains requirements for the patient’s compartment in terms of the working environment, ergonomic design and the safety of the crew and patients.This European Standard does not cover the training of the staff which is the responsibility of the authority/authorities in the country where the ambulance is to be registered.
This European Standard is applicable to road ambulances capable of transporting at least one person on a stretcher and excludes the transportation of hospital beds.
This standard also specifies requirements for ambulances intended to carry transport incubator systems.
The European Standard covers the specific requirements of each type of road ambulance which are
designated according to the patient condition e.g. patient transport road ambulance types A1, A2, B and C.
This European Standard gives general requirements for medical devices carried in road ambulances and used therein and outside hospitals and clinics in situations where the ambient conditions can differ from normal indoor conditions.

systems”, the secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by February 2021, and conflicting national standards

shall be withdrawn at the latest by March 2022.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 1789:2007+A2:2014.

This document has been prepared under a standardization request given to CEN by the European

Commission and the European Free Trade Association, and supports essential requirements of

EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this

document.

Introduction

Road ambulances are subject to a higher risk in use. The exact circumstances of operation cannot

always be planned or anticipated in detail.

Vehicles are designed so as to be safe. Design requirements can be derived from European and national

occupational safety and health legislation.

Under EU law, employers are responsible for carrying out a risk assessment (89/391/EEC, OSH

framework directive) and for provision of safe work equipment (89/655/EEC, use of work equipment

directive) that allows employees to work without their health being at risk.

The document was first developed in the late 1990s to define a common approach to requirements to

enhance patient and crew safety. The document has evolved and matured through several amendments

and revisions.
This latest revision work of EN 1789 has had two key objectives:

— The first objective was to revise the technical side of the document with more manageable

verification in mind, while maintaining the high quality and strict nature of the requirements.

— The second objective was to check all the references and regulations, paying special attention to EU

regulations and updated standardization rules.

Testing of special purpose vehicle, such as an ambulance, is complex. Multiple functions (e.g. fixations,

maintain systems, noise, illumination, heating, cooling etc.) may require numerous tests, which can be

destructive. In this edition, carefully planned tests according to worst-case scenario strategies have

reduced the number of destructive tests without sacrificing test qualities.

The previous edition of this standard (EN 1789:2007+A2:2014) contained a number of direct

references to EU regulations. According to CEN Internal Regulations Part 3:2017 and to avoid

duplication as well as outdated references and to enable use of this standard independently of the ECE

rules, EU regulations and directives, these references have now been removed from the normative

section of the standard.

This document is a reference document which can be used in support of regulations.

For the purpose of verification of an ambulance according to EU vehicle approval process, a section of

EN 1789:2007+A1:2010+A2:2014 (i.e. patient’s compartment) has been referenced directly in

Regulation (EU) 2018/858.

CEN/TC 239 has agreed to a transition period of a maximum of 18 months in order to accommodate the

different organisational structures that are necessary for the transport of patients are responsible for

providing sufficient time for the technical implementation. At the date of publication of EN 1789, the

presumption of conformity of the superseded standard has not yet been established in the Official

Journal of the European Union. Users of the standard are invited to check the date in the Official Journal

of the European Union against the transition period established by CEN/TC 239.

1 Scope

This document specifies requirements for the design, testing, performance and equipping of road

ambulances used for the transport, monitoring, treatment and care of patients. It contains requirements

for the patient’s compartment in terms of the working environment, ergonomic design and the safety of

the crew and patients. This document does not cover the training of the crew, which is the

responsibility of the authority/authorities in the country where the ambulance is to be registered.

This document is applicable to road ambulances capable of transporting at least one patient on a

stretcher and excludes the transportation of hospital beds.

This document also specifies requirements for ambulances intended to carry transport incubator

systems.

This document covers the specific requirements of each type of road ambulance, which are designated

according to the patient condition.

This document gives general requirements for medical devices carried in road ambulances and used

therein and outside hospitals and clinics in situations where the ambient conditions can differ from

normal indoor conditions.
