European foreword
This document (prEN 13814-1:2026) has been prepared by Technical Committee CEN/TC 152
“Fairground and amusement park machinery and structures - Safety”, the secretariat of which is held by
UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13814-1:2019+A1:2024.
EN 13814-1:2026 includes the following significant technical changes with respect to
EN 13814-1:2019+A1:2024.
This revision was initiated to incorporate the responses to the questions raised during the 2019 enquiry.
A complete review of rider loads to be used in design, testing and operation has been made. The section
regarding safety envelope definition has been completely reviewed. The introduction of the term
“retention device” helps to clarify the requirements for locking and latching systems. The overall section
has also been streamlined to facilitate reading. The accelerations section has been completely reviewed.
There are additional paragraphs to cover acceleration limits for children. The previous Annex H entitled
Safety Envelopes for Passengers in EN13914-2019 has been removed. The content of the table of hazards
has been integrated into Annex E. Clause 4.4 has been restructured and some further alignment with
Eurocode has been made. A new section provides a more precise way to define how fatigue load cycles
are counted. A new section has been added to explain how components that have reached their
theoretical design fatigue life can continue operation by defining initial and subsequent periodic
inspections that are required. An additional Annex for high speed go karts has been added. A review of
the terms for persons in the park or fairground has also been made.
EN 13814 consists of the following parts, under the general title Safety of amusement rides and
amusement devices:
— Part 1: Design and manufacture;
— Part 2: Operation, maintenance and use;
— Part 3: Requirements for inspection during design, manufacture, operation and use.
Introduction
The object of this document is to define safety rules related to structures and machinery, which are either
an integral part of, or constitute the amusement device itself. The safety rules are intended to safeguard
persons against the risk of accidents caused by deficiencies in design, manufacture and operation of such
structures and machinery.
Annex A (normative) provides guidance on electrical equipment and control systems.
Annex B (informative) provides control systems – best practices.
Annex C (informative) provides guidance of rider containment.
Annex D (informative) shows a typical layout of a device log for an amusement device.
Annex E (informative) lists hazards pertaining to amusement rides.
Annex F (informative) provides guidance on guest behaviour.
Annex G (informative) provides guidance on the limited accessibility to amusement devices.
Annex H (informative) explains acceleration effects on riders.
Annex I (informative) provides requirements for high speed go karts.
This revision was initiated to incorporate the responses to the questions raised during the 2019 enquiry.
For reference the initial replies were provided in document CEN/TR 18042. A complete review of rider
loads to be used in design, testing and operation has been made. The section regarding safety envelope
definition has been completely reviewed. The introduction of the term “retention device” helps to clarify
the requirements for locking and latching systems. The overall section has also been streamlined to
facilitate reading. The accelerations section has been completely reviewed. There are additional
paragraphs to cover acceleration limits for children. The previous annex H entitled Safety Envelopes for
Passengers in EN 13914-2019 has been removed. The annex has been removed and the table of hazards
has been integrated into Annex E. Sub-clause 4.4 has been restructured with some further alignment with
Eurocode has been made. As part of the fatigue analysis it is important to define how fatigue load cycles
are defined. The new section provides a more precise definition. A new section has been added to explain
how components that have reached their theoretical design fatigue life by defining initial and subsequent
periodic inspections that are required to be able to continue operation. An additional Annex for high
speed go karts has been added.
Terms used for the persons in the park of fairground was made. The aim was to standardize terms and
provide a logical set of definitions. Words for guest, participant, user, passenger and rider have been
reviewed and revised as necessary.
