This Technical Specification (CEN/TS) was approved by CEN on 30 May 2004 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This document (CEN/TS 81-29: 2004) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators
and moving walks”, the secretariat of which is held by AFNOR.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and
United Kingdom.
The CEN members are free to choose the way in which they implement this CEN Technical Specification. The CEN
members are asked to inform their national committee(s) about this CEN Technical Specification, and make it
available on request.
This document is a collection of interpretations related to EN 81-20 up to EN 81-28. Since the standards EN 81-1
and EN 81-2 have not yet been incorporated into the group EN 81-20 to EN 81-28 and interpretations to other
standards of this group are not yet available, this issue contains only information about interpretations related to EN
81-1 and EN 81-2. According to the progress in working out interpretations, this document will be amended.
This is the first edition of this CEN Technical Specification.

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:
 answers to questions regarding the understanding of clauses in standards ;
 feedback to the CEN-Committee responsible for a standard about the practical experiences resulting from
the use of the standard ;
 guidance to further development and improvement of standards following :
 experience, especially accidents and incidents ;
 progress in technology ;
 the state of the art.
Information concerning the procedure developed by CEN/TC 10 concerning the elaboration of interpretations is
shown in CEN Technical Report TR 81-10.

1 Scope
This document is a collection of interpretations related to EN 81-20 up to EN 81-28. Since the standards EN 81-1:
1998 and EN 81-2: 1998 have not yet been incorporated into the group EN 81-20 to EN 81-28 and interpretations
to other standards of this group are not yet available, this issue contains only information about interpretations
related to EN 81-1: 1998 and EN 81-2:1998.
Interpretations aim to improve 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.

Key-word(s) : Replacing interpretation No. :

Protection in the well ; rigid screen
QUESTION
In Clause 5.6.1 a rigid screen is required as a separation of the travelling area of the counterweight or
the balancing weight. This screen shall extend from a position of not more than 0. 30 m to a position of
at least 2.50 m. In case of compensating ropes/chains it is not possible to maintain the required 0.30 m
because of the diversion of these elements in the pit.
In those cases the screen can only extend from a higher position, or a slot with sufficient width for the
movement of the compensating means has to be provided. It would also be useful to leave a space for
checking the buffers.


INTERPRETATION
At the next revision of the standard, the following text will be submitted to the voting procedures
according to the internal rules of CEN:
In the case of lifts with compensating means it is regarded as acceptable that the lower end of the
screen is lifted to a height corresponding to the height of the fully compressed buffer(s).
If this additional free height is not sufficient for diverting the compensating means additional slot(s) may
be provided where necessary.

Filters ; hydraulic control and safety devices
QUESTION
According to Clause 12.5.7 a filter shall be installed between the shut-off valve and the down direction
valve.
An inspection body has raised the question whether 12.5.7 requires a filter also in front of the
emergency lowering valve.

INTERPRETATION
In the standard there is no requirement to place a filter in front of the emergency lowering valve.

Fixing of the glass panels ; glass
QUESTION
Contrary to table J.2, there is no indication in table J.1 for which type of fixing of the glass panels (all
sides, 2-side, 4-point) the stated panel dimensions are valid.
Based on our experience the fixing of the glass panels is of great importance.

INTERPRETATION
The values in table J.1 are valid for a 4-side fixing of the glass panels in a metal frame.

Key-word(s) : Replacing interpretation No. :

Dimensions of the glass panels ; glass
QUESTION
In table J.1 the dimensions of the glass panels is indicated by the “diameter of inscribed circle”. Is this
statement valid for square panels only, or can it also be used for rectangular panels, the sides of which
correspond to the “diameter of inscribed circle”?

INTERPRETATION
The values in table J.1 are also valid for rectangular glass panels.
Deviating from the mathematical definition, the wording 'inscribed circle' in this context means the
largest circle which can be placed inside the shape of a glass panel.

Door motor ; overload protection
QUESTION
EN 60204, by Clause 7.3, excludes the necessity of overload protection if the power of the motor is
less or equal to 0,5 kW.
Can the Committee accept the rule according to EN 60204, Clause 7.3, that overload protection is only
necessary with a motor above 0,5 kW for lifts as an exception to Clause 13.3.2 ?

INTERPRETATION
Yes, this rule can be accepted

QUESTION
In the case that more than one entrance to a machine room is arranged, each entrance shall be
provided with a mainline switch in the vicinity of the entrance.
If one of the main switches is “switched off” and “locked out”, than it shall not be possible to switch the
mains on at the other entrance.
Is our interpretation correct ?

INTERPRETATION
Yes, the interpretation is correct.
