European foreword
This document (CEN/TR 18042:2024) 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.
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.
Any feedback and questions on this document should be directed to the users’ national standards body.

Introduction
Interpretations and no-action decisions
This document contains replies to requests for interpretations concerning the understanding of clauses
in EN 13814:2019 and its parts. The replies concern those requests that have resulted in an
interpretation or a decision that no action is required as the standard is sufficiently clear.
An interpretation does not have the same status as the text of the standard. However, following an
interpretation gives assurance that the relevant clause of the standard has been correctly applied. An
interpretation is a clarification of the meaning of the standard.
Disclaimer
The interpretations have been derived by expert groups of CEN/TC 152/WG 1 and have been circulated
to National Standards Bodies for approval. The information contained herein does not reflect the full
formal approval by CEN or CEN member bodies. It should be noted that the interpretations are neither
part of any standard nor have been referenced in the Official Journal of the European Union.
Requests for interpretations may be submitted by a CEN member body through its national committee
or by a CEN/TC 152 liaison (but not directly by an individual or a company) – in accordance with the
interpretation protocols agreed by CEN/TC 152/WG 1. The requests are then channelled to the
CEN/TC 152/WG 1 interpretation panel, which will then deal with the request.
A request for an interpretation may lead to:
a) an interpretation of the standard with no action to the standard (no revision and no amendment)
This should reflect a reasonable interpretation of how the standard should be used, taking into
account:
— the wording of the standard;
— the rationale of the standard;
— the history of the standard.
This is also applicable when it is agreed that the standard appropriately specifies how amusement
rides and amusement devices shall be assessed.
b) a proposal for an amendment of the standard
This is applicable when it is agreed that the standard is deficient in some way.
NOTE Interpretation and no-action decisions are published in EN 13814-1:2019/prA1:2023, which will be
updated on a regular basis
Proposals for amendments will be progressed as new work item proposals in accordance with
CEN rules.
c) a future revision
This is applicable when the standard is not clear and a suitable amendment cannot be found to fully
clarify the question. It is also a case when an opportunity was identified to further add to the
content. Further work is needed on existing requirements or new requirements may need to be
drafted.
Proposals for a revision will be progressed as a new work item proposal in accordance with CEN
rules.
Answers to requests for interpretations
Since requests for interpretations are submitted through a CEN member body, it is assumed that the
member body will keep itself informed about decisions concerning the request and its progress and will
itself inform the originator of the request as appropriate.

Part 1: Design and manufacture
4.1 General. Interpretation request – ESMA
Question
I am contacting you following a visit to your website and reading about EN 13814.
We are in the Leisure Karting industry and we often face national administrations referring to
EN 13814 when it comes to certification and applicable norms to our activities when we claim
EN 16230-1 and EN 16230-2 is better adapted.
However, the answer I always get is the same and is: We don’t know about EN 16230-1 and −2, we
always worked with EN 13814, why should be apply one instead of the other? Is there a clear line of
where one applies versus the other?
Initially, my understanding was that EN 13814 was only applying to mobile temporary rides but it also
looks like it applies to permanently installed rides. In our industry, we only refer to permanent venues
dedicated to Karting (or sometimes part of multi entertainment venues) and we can’t figure out how to
justify application of 1 norm versus the other.
Could you help with this?
Reply
No action/Clarification
EN 13814 is applicable only to “go karts” installation which are part of amusement parks and
fairgrounds:
“5.2.5 Speedways/Go-karts
5.2.5.1 General
These requirements are specific to amusement parks and fairground go-karts.”

4.2.1 1. Scope (interpretation request – SII)
Question
SII expert committee is adopting the EN 13814: May 19 standards with national modifications.
In the scope of EN 13814-1, the rides that are not covered by the standard are specified, and then it is
mentioned that “for all the equipment not covered by the requirements of EN 13814-1, the relevant
standards apply”.
However, the next line of the scope states that the standard can be used in the design of any similar
device not explicitly mentioned.
Our question is what standard applies in the case of such similar device if it is covered by a relevant
standard. Does the relevant standard apply, does this standard apply, or both? Or was this line intended
only for devices without relevant standards?
Furthermore, it would be helpful to learn whether the rides that are not included in the scope do have
relevant standards that apply.

If applicable standards exist for particular equipment, they should be applied. EN 13814 can be applied
in the absence of any applicable standards.
4.2.2 1. Scope (interpretation requests – UNI 002-013, 001-086)
Question
“This document is applicable to manufacturing and major modification of amusement devices and rides
for designs after the effective date of publication”.
How it shall be interpreted, that it’s applicable only to new Design developed after the date of
publication of EN 13814:2019?
What about the ride manufactured in compliance with existing design but built after the date of
publication of EN 13814-1:2019?

From November 2019 till May 2022 the versions EN 13814:2004 and EN 13814:2019 were valid.
The current version in force is 2019.
National regulation bodies and/or contractual agreement may decide which version they accept.
4.3 3. Terms and definitions
4.3.1 3.4 Barrier (interpretation request – UNI 003-015)
Question
What is it in practice the difference between 3.4 Barrier and 3.15 Guardrail?
Reply
Clarification
A guardrail does not prevent a person for passing beneath it, whereas a barrier does.
Revision
Discuss the definitions of Barrier/Guardrail/Fence.
4.3.2 3.5 Closed restraint (interpretation request – DIN X5)
Question
The term “closed restraint” should be rephrased because of distinction to “minimum closed restraint
position” and also due to the missing information of the body-fitted requirement.
Explain what closed restraint in relation to restraint position means.
Suggestion for new revision:
Change the term 3.5 body-fitted restraint position: the restraint position in which the restraint (3.37) is
closed tight to the individual body of the passenger and intended to remain during the operation of the
device in order to restrain the passenger (3.28).

Revision
An improvement for the definition of “closed restraint” will be proposed for the next revision.
4.3.3 3.23 Machinery component (interpretation request – UNI 004-014)
Question
“machinery component
component which form part of an assembly in which at least one component moves (excluding
vibration and deformation)”
Is it the complete definition or are there other requirements?

No action/Clarification
At this stage this is the complete definition.
4.3.4 3.41 Safety-related part or component (interpretation request – UNI 005-016)
Question
“safety-related part or component
part or component of an amusement device (3.1) on which the safety of the passengers (3.28) is
dependent as identified in the design risk assessment (3.9) and/or the operation and use risk
assessment (3.26)
Seems that take in consideration passenger safety only.
What about public, spectators and operators (including attendants and staff)?
Reply
This is true.
Revision
For discussion during next revision.
4.3.5 3.XX (interpretation request – DIN X4)
Question
The term “minimum closed restraint position” should be defined in Clause 3.
Plain Speak: The “minimum closed restraint position” of a restraint is a dedicated restraint position
which limits the acceptable corpulence of a rider.
Add the term: 3.xx minimum closed restraint position: The restraint position in relation to the seat
which defines together with the seat the range of acceptable application of the restraint system.
NOTE 1 to 3.xx: The monitoring of the minimum closed restraint position limits the acceptable
corpulence of a rider and ensures the area of locking has been reached. If a tight to the body closed
restraint would not reach the minimum closed position the passenger would not be allowed to ride.
NOTE 2 to 3.xx: Regardless of the minimum closed restraint position safe retention of the passenger
requires in any case the restraint is reaching the body-fitted restraint position (3.5).
Reply
Clarification
A commonly used term in the industry is “minimum closed restraint position”. This position is defined
as the position of the restraint with the respect to the seat which is considered as a minimum closed
position in order to guarantee the acceptable range of body dimensions. Any technical monitoring of
restraint position is related to the “minimum closed restraint position” (see Table 12 and Table A.2) and
as such there is no guarantee that the restraint is fully restraining the passenger (tight to the body). The
responsibility of checking that the restraint is tight to the passengers’ body remains with the attendant
(3.3) A.2.5.2.

For discussion during next revision.
4.4 4. Requirements for design analysis
4.4.1 4. Requirements for design analysis (interpretation request – UNI 092)
Question
With reference to EN 1993-1-1, Eurocode 3: Design of steel structures — Part 1-1: General rules and
rules for buildings, as mentioned in the chapter “Clause 2 Normative references” of EN 13814-1:2019,
related to the following condition in paragraph “Subclause 1.1.2 Purpose and field of application of
Part 1-1 of Eurocode 3” where it is mentioned that “EN 1993-1-1 provides general design rules for steel
structures with thickness of the material t > = 3 mm. It also provides additional provisions for the
structural design of steel buildings.”.
Does it mean that there mustn’t be structural elements duly calculated and verified with thicknesses
less than 3 mm?
In addition, the object specifies the term “buildings”, but it is clear that a tourist train is not a building:
so, are there margins of applicability of the aforementioned regulation? The decision and discretion are
delegated to the builder/structural engineer of the product or to whom?

Elements below 3 mm which are not covered by Eurocode, can be treated as machinery components
and calculated accordingly.
4.4.2 4. Requirements for design analysis (interpretation request – UNI 093)
Question
With reference to EN 1993-1-8, Eurocode 3: Design of steel structures — Part 1-8: Design of joints, in
the paragraph “Clause 4 Welded connections – Subclause 4.1 General” it says that “(1) The indications
of this section apply to weldable structural steels conforming to EN 1993-1-1 and to material
thicknesses of 4 mm and higher” and also “For welding on thinner material thicknesses it is
recommended to refer to EN 1993 part 1.3, while for welding in hollow structural sections with a
thickness of 2,5 mm and higher, the indications are provided in Clause 7 of this standard.”.
In addition, in the paragraph “Clause 7 Connections of hollow sections – Subclause 7.1 General –
Subclause 7.1.1 Purpose” of the same standard, it is reported that “(5) It is recommended that the
nominal wall thickness of hollow sections is not less than 2,5 mm.”.
So, which is the interpretation of all these restrictions? In our opinion, there is a clear contrast with
what declared in the scope of the EN 1993-1-1, isn’t it?

Question
With reference to EN 1993-1-3, Eurocode 3 — Design of steel structures — Part 1-3: General rules —
Supplementary rules for cold-formed members and sheeting:
Why this regulation cannot fall within the scope of application of EN 13814-1:2019 (due to existing and
already approved uses in the amusement ride sector)?

Clarification
This standard can be used for static loading conditions. Any dynamic loading conditions (more than
10 000 load cycles in total or if the stress is below the endurance limit) need to be evaluated by other
means.
