European foreword
This document (CEN/TS 115-4:2020) has been prepared by Technical Committee CEN/TC 10 “Lifts,
escalators and moving walks”, the secretariat of which is held by AFNOR.
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 CEN/TS 115-4:2015.
Interpretations 138 till 150 are added in this edition compared to CEN/TS 115-4:2015.
EN 115 is divided into the following parts:
— EN 115-1, Safety of escalators and moving walks - Part 1: Construction and installation;
— EN 115-2, Safety of escalators and moving walks - Part 2: Rules for the improvement of safety of existing
escalators and moving walks;
— CEN/TR 115-3, Safety of escalators and moving walks - Part 3: Correlation between EN 115-
1:2008+A1:2010 and EN 115-1:2017 [Technical Report];
— CEN/TS 115-4, Safety of escalators and moving walks - Part 4: Interpretations related to EN 115 family
of standards [Technical specification; the present document].
This document is a collection of interpretations related to the EN 115 series. For the time being, this
collection of interpretations relates to EN 115-1. According to the progress in working out
interpretations, this document will be amended and/or completed.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
Introduction
Standards reflect the consensus of the best European expertise and are prepared with highest care.
Product standards cannot be formulated in such a way that they describe all possible technical solutions
and therefore exclude all uncertainties regarding the understanding of the required provisions. On the
other hand, technology is in a permanent evolution, the progress of which cannot be incorporated into
standards quickly enough.
Interpretations are a practical way to give:
a) answers to questions regarding the understanding of clauses in standards;
b) feedback to the CEN-Committee responsible for a standard about the practical experiences resulting
from the use of the standard;
c) guidance to further development and improvement of standards following:
1) experience, especially accidents and incidents;
2) progress in technology;
3) state of the art.
1 Scope
This document is a collection of interpretations related to the EN 115 series. This document collects
interpretations to EN 115-1:2008+A1:2010 and EN 115-1:2017. Interpretations to other standards of the
EN 115 series will be added when they are available.
Interpretations aim to improve the understanding of the clause(s) they are referring to and by that
facilitating common understanding between manufacturers, lift installers, notified bodies, inspection
bodies and national authorities.
Interpretations do not have the same status as the European standards to which they are related.
However, the application of interpretations give to the interested parties confidence that the relevant
European standard has not been wrongly applied.

Increased height of the web on step treads side
QUESTION
Is it permitted to have an increased height of the web at both sides of the step tread (demarcation
lines opposite to the skirt panels)?
INTERPRETATION
Increased height of the rib (web) is permitted as long as the same safety level as for a totally flat
step/pallet will be ensured. This shall be proofed in detail by risk analysis.

Form of 25 cm area
QUESTION
5.5.2.4 and 5.5.3.3 specify an area of 25 cm on to which the force shall be applied.
Which form (square, circle, rectangle) shall this area have?
INTERPRETATION
With the definition of 25 cm , it was intended to precise the term “lump load” used in former
codes.
Normally, the equipment for such tests has a circular or square surface so that such formed areas
will be the practice in general.
This will be considered in the next revision of the standard.

Load on skirting
QUESTION
1.   5.5.3.3 defines the load carrying ability of the skirting and deformation. Does this apply to
the whole skirting or only to the area of 25 mm according to 5.5.3.2?
2.   If the whole skirting has to be dimensioned for the test load, shall then also the comb plate
lighting, if installed in the skirting, withstand this load?

INTERPRETATION
1.   The load and deflection requirements of 5.3.3.3 shall be met up to a height of 25 mm above
the line of the step nose or the tread surface of the pallets or belt where the risk of
entrapment exists. Above the height of 25 mm, the force requirements of the balustrade of
500 N (see 5.5.2.4) shall be fulfilled.
2.   The comb plate lighting has to withstand the test load according to 5.5.3.3 if the lighting or
part of it is arranged within the area of skirting of 25 mm above the tread surface.
All other requirements of the skirting according to 5.5.3 are still valid. This includes that under
the force requirements above the skirting shall remain plain and butt-joined according to 5.5.3.1.
At the next revision of EN 115-1:2008+A1:2010, 5.5.3 has to be amended accordingly.

Automatic start in two-direction mode
QUESTION
Is it allowed to make an arrangement as follows:
The escalator can start automatically in both directions by a user passing a light barrel depending
on the direction from which the user is coming. Both directions can be predetermined directions
at the same time.
When the escalator has stopped after a sufficient time (5.12.2.2.2), the signal lights show “green”
light in both landings.
However, when a user comes to the end of a running escalator by passing the “red” signal light
and stays near to the comb waiting till the escalator has stopped, there is another light barrel
installed in the skirting above the comb and when the user passes this light barrel, the escalator
stops and can be re-started only with a key.
INTERPRETATION
Operation in “two direction mode” for escalators with automatic start is permitted under the
following conditions:
a)  On escalators which can start automatically in either direction (“two direction mode”) by the
entering of a user, the “two direction mode” and the momentary capable direction of travel
shall be clearly visible to the user and marked distinctly on the escalator (see 7.2.2 plus “two
direction mode” sign). They shall start in the direction determined by the user entering first.
When the escalator is started by a user from either direction, the indicator opposite from the
initiated starting side shall automatically indicate “no entry” (see 7.2.2).
b)  Measures for control and/or monitoring function shall prevent:
–   failures of the control elements actuating the automatic start at the entries (e.g. no or
partly no detection of users);
–   a restart of the step band when a user has entered the area between the control element
and the comb intersection line and the step band is stopped.
c)  Control and monitoring function shall be regarded as electric safety devices and shall be
applied as safety switches (5.12.1.2.2), fail safe circuits (5.12.1.2.3) or SIL 1 according to
PESSRAE (5.12.1.2.6).
The application of “two direction mode” is not permitted for moving walks.
This will be considered in the next revision of the standard.

existence of fixed stairs forbidden?
The height on the unrestricted area shall be not less than 2,30 m, if the building's regulation does
not impose more?
INTERPRETATION
The existence of fixed stairs is forbidden in the unrestricted area. The area shall be flat. A
maximum inclination of 6° is permissible.
In A.2.1, a building height is stated for the unrestricted area which is necessary from the view of
machinery safety. National authorities are free to request more.
This will be considered in the next revision of the standard.

Barrier to prevent access of shopping trolleys and baggage carts
QUESTION
In EN 115-1:2008+A1:2010, I.1 requires suitable barriers to prevent access of shopping trolleys
and baggage carts.
Is the former interpretation related to EN 115:1995 still valid? What are the requirements for a
“suitable” barrier?
INTERPRETATION
The old interpretation is referring to EN 115:1995 including Amendments 1 and 2 and is not
valid for EN 115-1:2008+A1:2010.
To protect the use of shopping trolleys and baggage carts on escalators resp. moving walks, the
requirements concerning the barriers are as follows:
–  The barrier shall be installed at the entrance only. An installation at the exit is not permitted
in the unrestricted area.
–  The design of the barrier shall not create another risk.
–  The free entrance width between ends of the newels and barriers – and between barriers
itself - shall be at least 500 mm (see EN 349) and less than the width of the type of shopping
trolley or baggage cart which will be used.
–  The height of the barrier shall be between 900 mm and 1 100 mm.
–  The load the barrier and its fixation has to withstand: At a height of 200 mm a horizontal
force of 3 000 N applies. This force results from an impact of a chassis of a loaded shopping
trolley (according to EN 1929-1) / baggage cart loaded with 160 kg moving with a speed of
1 m/s.
–  The fixation of the barrier shall preferably be done at the building structures. It is also
permitted to fix it at the floor plate. In that case, when the defined forces apply, there shall
be no permanent deformation and increased/additional gaps.
–  If the escalator/moving walk is dedicated to work in both directions, the presence of the
removable barrier shall be electrically monitored preventing wrong positioning of the
barrier, except when under maintenance condition.

Stiffness of exterior panel
QUESTION
5.2.1.2 defines the stiffness of the exterior panels as follows:
5.2.1.2 The exterior panels shall withstand a force of 250 N at any point at right angles on an
area of 25 cm without breakage or deflection resulting in any gap. The fixing shall be designed
in that way to carry at least twice the dead load of the enclosure.
When we have 2 panels side by side we have automatically a small gap between them. How can
we fulfil then 5.2.1.2?
INTERPRETATION
5.2.1.2 is a new requirement in EN 115-1 ensuring that exterior panels will be rigid enough to
protect from contact with moving parts inside the escalator/moving walk and/or creation of
points of entrapment. The requirement derives from the balustrade requirement and is similar
to the interior panel.
In 5.5.2.4, the 3rd paragraph states, “gaps between the interior panels of the balustrade shall be
not wider than 4 mm.”
The same applies also to the exterior panels as long as movable parts are reachable.
This paragraph will be updated in the next revision of this standard as follows:
“5.2.1.2 The exterior panels shall withstand a force of 250 N at any point at right angles on an
area of 25 cm without breakage. Any gaps or openings are restricted to 4 mm where there is a
risk of contact with moving parts. The fixing …”

Nr.:
Stopping of succeeding escalators
QUESTION
Item h) in Table 6 indicates requirement of “stopping of a succeeding escalator or moving walk
where an intermediate exit does not exist….” especially for successive escalators, as shown in
A.2.6 of EN 115-1:2008+A1:2010.
In our opinion, this should read as 'stopping of a preceding escalator'.
Key
1   defective escalator
2   preceding escalator
3   STOP THIS!
4   No exit
5   side view
Figure 1
Definitely, shutting down all the successive escalators on the same route will be helpful.
However, stopping a “preceding escalator” is relatively more important because this will prevent
feeding more passengers in front of the defective escalator “which does not have intermediate
exit” (see Figure 1 above).
If the preceding escalator is not stopped, more number of passengers will arrive in front of the
defective escalator and there will not be enough space. Since there is no intermediate exit, the
passengers cannot move out of the escalators path. There will be overcrowding, tripping, falling
over, etc. which will be a dangerous situation.
INTERPRETATION
The intention of the code is exactly as described in the question. The requirement is to stop the
escalator, if the succeeding escalator will stop where no exit exists. Table 6 is related to the
escalators where the action has to be taken and where the requirements are listed.
So the heading of the table and the paragraph has to be read together which means
“Requirements for monitoring …. (h) …. of a succeeding escalator stopping…”.
That means when travelling on the preceding escalator and the succeeding one will stop, the
preceding one also shall stop. The table is listing the events when the escalator is stopping.

QUESTION
The edge, along the nose line of the steps, has a radius as shown in EN 115-1:2008+A1:2010,
Figure 2. The measurement of the maximum allowable gap of 6 mm shown on the drawing is
taken at a point below the tread surface where the radius ends.
5.3.5 states, “The clearance between two consecutive steps or pallets in any usable position
measured at the tread surface shall not exceed 6 mm.”
Can the committee confirm that location for measurement is as shown on the drawing and the
drawing can be considered as a correct interpretation of 5.3.5?
INTERPRETATION
The measurement shall be carried out as the dimensions of the gaps are indicated in Figure 2.
For pallets, the measurements have to be done according Figures 6 and 7.

Fire protection of steps and pallets
QUESTION
“…, pallets/steps, … shall be at least class C according to EN 13501-1:2007, 11.5.”
In the past, steps with demarcation parts as plastic inserts were used and they never caused any
fire hazard.
Does this requirement include parts like plastic inserts on the tread surface?
INTERPRETATION
Yes, this requirement applies also for the plastic inserts. The compliance test according to
EN 13501-1 (SBI Test according EN 13823) shall be carried out in the vertical position where the
tread surfaces are forming the test surface. This test is applicable for steps where the plastic
inserts are on the tread surface only because in this configuration, a flame spread over the
complete step band is not possible.
In a configuration where plastic inserts are used in the step tread AND the step riser, a flame
spread over the complete step band is possible. In this case the test according EN 13501-1 (SBI
Test according to EN 13823) has to be done solely with plastic insert material forming the whole
test surface.
This will be taken into account in the next revision of the standard.

Additional stop switch at handrail level - Building interfaces to
Nr.:
escalator/moving walk
QUESTION
–   What are the definition of the term “at handrail level” and the position of the stop button?
–   Is this requirement related to the stop button or to the entire installation (e.g. including
housing)?
–   Are installations slightly above or below the handrail permitted, avoiding hidden installation
or conflict with installations close to the handrail?
The intention of this requirement is quite clearly defined in A.2.5. A more precise specification of
the requirements related to handrail and stop switch or stop switch housing would be
appreciated.
INTERPRETATION
–   The intention of the wording “at handrail level” is to point out an installation of the stop
switch close to the handrails within the reach for the passengers with a distance from the
comb intersection line in the range of 2 000 to 3 000 mm (see Figure 1 below).
–   The installation can be regarded within a vertical range of 200 mm below and 400 mm above
the handrails (see Figures 2 and 3 below). Within that range, the stop button can be
considered as “not hidden”.
–   Assemblies in the inside of the balustrade are permitted when they are arranged and formed
in such a manner as to eliminate any risk of harm caused by trapping.
–   The vertical limitations are related to the middle of the actuator (e.g. push button or handle).

Fixed devices in unrestricted areas
QUESTION
Fixed devices like guiding barriers for improving the traffic flow or traffic columns, especially in
the unrestricted area, are not clearly defined in EN 115-1. What are the requirements on these
devices?
INTERPRETATION
Where fixed devices such as guiding barriers and/or traffic columns are necessary in the
unrestricted area, the following requirements, to avoid any additional risk, shall be met. The
safety distances are defined according to EN 349.
1   General requirements
–   The devices shall have no sharp or cutting edges.
–   There shall be no pinching hazard, especially with the moving handrail.
–   The devices and its fixation shall withstand a horizontal force of 1 kN/m applied to the top
of the device. This force results from EN 1991-1-1, Category C2-C4 and D
NOTE Guiding barriers and traffic columns are not intended as safeguards against falling down,
for which higher forces and further regulations are applicable.

–   The devices shall preferably be affixed to the building structure or the escalator/moving
walk structure. If affixed to a fixed part of the floor plate, when the defined forces are
applied, there shall be no permanent deformation and no increased/additional gaps.
–   A further improvement of the level of safety is accomplished by attachment of caution
markings to the columns to improve the visual recognition of the obstruction, or by
installing round columns resp. columns with diagonal deflectors in front of the columns, to
eliminate the risk of getting stuck with e.g. luggage.
