identical text or by endorsement, at the latest by June 2026, and conflicting national standards shall be
withdrawn at the latest by December 2027.
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 has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
This document is part of the EN 81 series of standards. The structure of the EN 81 series is described in
CEN/TR 81-10:2008.
Any feedback and questions on this document should be directed to the users’ national standards body.

Introduction
0.1 General
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.)
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
0.2 General remarks
0.2.1 The object of this document is to define safety rules related to passenger lifting appliances with
a view to safeguarding persons and objects against the risk of accidents associated with the normal use,
maintenance and emergency operation of lifting appliances.
a) Persons to be safeguarded:
1) users, including passengers, persons waiting at the landings, maintenance and inspection
personnel (see EN 13015:2001+A1:2008);
2) persons at the landings and outside of the well, or any machinery spaces, who can be affected by
the lifting appliance.
b) Property to be safeguarded:
1) loads in carrier;
2) components of the lifting appliance installation;
3) building in which the lifting appliance is installed.
0.2.2 A study has been made of the various possible hazards with lifting appliances (see Annex I).
0.3 Principles
0.3.1 In drawing up this document the following principles have been used.
0.3.2 This document does not repeat all the general technical rules applicable to every electrical,
mechanical, or building construction including the protection of building elements against fire.
It has, however, been necessary to establish certain requirements of good construction, either because
they are peculiar to lifting appliance manufacture or because in the case of lifting appliance utilization
the requirements can be more stringent than elsewhere.
0.3.3 As far as possible this document sets out only the requirements that materials and equipment
have to meet in the interests of safe operation of lifting appliances.
0.3.4 Risk assessment, terminology and technical solutions have been considered taking into account
the methods of EN ISO 12100:2010, EN ISO 14798:2013 and the EN 61508:2010 series of standards.
0.3.5 In order for EN 81-42 to be a widely applicable standard the average mass of a person has been
determined to be 75 kg.
0.4 Assumptions
0.4.1 In drawing up this document the following assumptions have been made.
0.4.2 Users have to be safeguarded against their own negligence and unwitting carelessness when
using the lifting appliance in the intended way.
A user can, in certain cases, make one imprudent act. The possibility of two simultaneous acts of
imprudence and/or the abuse of instructions for use is not considered in this document.
0.4.3 With the exception of the items listed below which have been given special consideration, a
mechanical device built according to good practice and the requirements of this document, including
uncontrolled slipping of the suspension means on the traction sheave, will not deteriorate to a point of
creating hazard without the possibility of detection provided that all of the instructions given by the
manufacturer have been duly applied:
a) breakage of the suspension;
b) breakage and slackening of all linkage by auxiliary ropes, chains and belts;
c) failure of one of the mechanical components of the machine brake which take part in the application
of the braking action on the drum or disk;
d) failure of a component associated with the main drive elements and the traction sheave;
e) rupture in the hydraulic system (jack excluded);
f) small leakage in the hydraulic system (jack included).
0.4.4 The possibility of the safety gear not engaging, should the carrier free fall from a stationary
position at the lowest landing, before the carrier strikes the end stop(s) or buffer(s), if any, is considered
acceptable.
0.4.5 The requirements of this document are such that the possibility of a failure of an electric safety
device or a safety component complying with all the requirements of this document needs not to be taken
into consideration.
1 Scope
1.1 This document specifies safety requirements for design, construction and manufacturing of
permanently installed electrically powered vertical lifting appliances affixed to a building structure
intended for use by persons, including persons with disability:
— travelling vertically between predefined levels along a guided path whose inclination to the vertical
does not exceed 15°;
— supported or sustained by rack and pinion, rope traction drive, noncircular elastomeric-coated
suspension means (hereafter called traction belts) traction drive, rope positive drive, chains, timing
belts, screw and nut, guided chain or hydraulic jack (direct or indirect);
— with enclosed wells;
— with a rated speed not greater than 0,15 m/s;
— with the carrier completely enclosed;
— with a temperature in the well and in the machinery spaces between +5 °C and +40 °C.
1.2 This document does not specify additional requirements for:
— lightning protection;
— operation subject to ATEX rules;
— lifting appliances whose primary function is the transportation of goods;
— earthquakes, flooding;
— firefighting and evacuation;
— noise and vibrations;
— the transport of type-C wheelchairs as defined in EN 12183:2022 and/or EN 12184:2022;
— vertically sliding doors.
1.3 Components incorporated in a lifting appliance installation are:
a) designed in accordance with usual engineering practice and calculation codes, taking into account all
failure modes;
b) of sound mechanical and electrical construction;
c) free of defects.
1.4 This document is not applicable to lifting appliances manufactured before the date of its
publication.

3.1
design working load
rated load + overload of one person (equivalent to 75 kg)
3.2
end stop
element of the lifting appliance (i.e. the ram comes into contact with its cushioned stop) or of the well (i.e.
the floor of the pit) to prevent the lifting appliance to be driven beyond the extremes of travel
3.3
full travel
