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.

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.

Number of inspection control on site
QUESTION

For the inspection control for 2 parallel or criss-cross escalators, shall we have 2 portable control

devices or is it sufficient to have one control device for both?

According to the Machinery Directive, each escalator/moving walk shall be equipped with a

permanent available portable control device.

The wording of the standard (5.12.2.5) will be improved in the next revision of the standard.

Rigid deflectors
QUESTION

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

in order to prevent vandalism?
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.
