European foreword
This document (CEN/TS 115-4:2015) 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 [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document supersedes CEN/TS 115-4:2014.
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 115:1995
and its amendments and EN 115-1:2008 [Technical Report];
• CEN/TS 115-4, Safety of escalators and moving walks - Part 4: Interpretations related to EN 115
family of standards [Technical specification; this 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 organizations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland,

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 Technical Specification is a collection of interpretations related to the EN 115 series. This
document collects interpretations to EN 115-1:2008+A1:2010. 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 should 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.

Unrestricted area, fixed stairs, building height
QUESTION
At the landings of the escalator, on the unrestricted area of 2,50 m (2,00 m) depth, is the 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.

QUESTION
Are deflectors which correspond to A.2.4 of EN 115-1:2008+A1:2010 permitted to be pendulous, in

INTERPRETATION
Deflectors shall be mounted rigidly in order to meet all requirements. A pendulous deflector can be used
in addition before the mandatory rigid deflector.
The rigid mounting of the deflector 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.

Testing of steps and pallets drive
QUESTION
Regarding the step or pallet chain mentioned in 5.4.3.2:
1. Pallet chains are not mentioned
2. It is not clear, whether every step or pallet chain must be subjected to a tensile test or a type test for
every chain type is sufficient.
INTERPRETATION
1. Pallet chains are missing in the paragraph. This shall be updated during the next revision
2. To fulfil the requirement of EN 115-1 it is sufficient that every design of step or pallet chain has
passed a type tensile test.
Hence, in the next revision, Table 7 will identify this requirement. In addition, the type test report should

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 … “

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.

Measurement of step to step gap
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.
This will be considered in the next revision of EN 115-1.

Fire protection of steps and pallets
QUESTION
“…, pallets/steps, … shall be at least class C according to EN 13501-1:2007+A1:2009, 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.
2 Placement requirements
A) In case of a free-standing guiding barriers or traffic columns, they shall be positioned in a minimum
horizontal distance (radius) of 500 mm from any point of the handrail, and outside of the centre line
of the handrail (see Figures 1 a)/b) on Page 3, Figure 8 on Page 7).
B) This minimum distance may be reduced to 300 mm, provided that the guiding barriers or traffic
columns are positioned outside of the centre lines of the handrails and an additional barrier is
installed between the guiding barriers or traffic columns and the vertical centre line of the
balustrade newel (see Figures 2 a)/b) on Page 3, Figure 8 on Page 7).
The additional barrier shall have a lateral distance between 80 mm to 120 mm of the handrail outer
edge and shall close at least the area between the actual lowest point of the handrail entry into the
newel (h , see 5.6.4.1 of EN 115-1:2008+A1:2010) and the balustrade decking profile and shall have
filled inlets with gaps < 25 mm with no pinching risk (see Figures 6 a)/b)/c)/d) on Page 5).

CEN INTERPRETATION
Page 2 of 7
C) Further reduction to 180 mm is permitted, as long as the guiding barrier or traffic column is
positioned outside of the outer edge of the handrail and an additional barrier is installed between
the guiding barrier or traffic column and the vertical centre line of the balustrade newel
(see Figures 3 a)/b) on Page 4, Figure 8 on Page 7).
The additional barrier shall have a lateral distance between 80 mm to 120 mm of the handrail outer
edge and shall close at least the area between the actual lowest point of handrail entry into the
newel (h ) and the balustrade decking profile and shall have filled inlets with gaps < 25 mm with no
pinching risk (see Figures 6 a)/b)/c)/d) on Page 5).
D) A reduction of the horizontal distance to 100 mm (identical to the minimum value of h ) is
permitted, only if the guiding barrier or traffic column is of a round shape and is positioned outside
of the outer edge of the handrail and an additional barrier is installed between the guiding barrier or
traffic column and the vertical centre line of the balustrade newel (see Figures 4 a)/b) on Page 4,
Figure 8 on Page 7).
The additional barrier shall have a lateral distance between 80 mm to 120 mm of the handrail outer
edge and shall close at least the area between the actual lowest point of handrail entry into the
newel (h ) and the balustrade decking profile and shall have filled inlets with gaps < 25 mm with no
pinching risk (see Figures 6 a)/b)/c)/d) on Page 5).
3 Traffic columns requirements
The height of traffic columns shall be at least the height of the handrail level.
4 Guiding barriers requirements
The height of guiding barriers shall be at least the height of the balustrade decking, that is at least
the vertical distance between floor level and the upper edge of moving handrail minus thickness of
the moving handrail minus at least 25 mm (see b , A.2.2 of EN 115-1:2008+A1:2010).
5 Additional requirements
An arrangement of guiding barriers or traffic columns completely outside of the unrestricted area is
not subject of this interpretation. The safety distances according to EN 349 shall be respected.
If fixed devices are placed inside the unrestricted area, the size of the unrestricted area shall remain
the same and in this case be extended in the length (see Figure 7 a)/b) on Page 6).
