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.
This is the first edition of this CEN Technical Specification.
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,

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 standards to which they are related. However, the
application of interpretations should give to the interested parties confidence that the relevant standard has
not been wrongly applied.

Form of 25 cm area
QUESTION
Above paragraphs 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 practise in general.
This will be considered in the next revision of the standard.

Load on skirting
QUESTION
1. Subclause 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 stops the escalator 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 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°degree 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.

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 115–1:2010, 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.
