Introduction
This document specifies health and safety requirements, as well as some functional and performance
requirements, for passenger boarding bridges (PBB) intended for passenger embarking/disembarking
of all aircraft types commonly in service in civil air transport.
The minimum essential criteria are considered to be of primary importance in providing safe,
serviceable, economical and practical PBB. Deviations from the recommended criteria should occur only
after careful consideration, extensive testing, risk assessment and thorough service evaluation have
shown alternative methods or conditions to be satisfactory. Such deviations are outside the Scope of
this document and a manufacturer should be able to demonstrate an equivalent level of protection.
The machinery concerned and the extent to which hazards, hazardous situations and events are
covered are indicated in the Scope of this document.
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 at 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.

5 Safety requirements and/or measures
5.1 General requirements
5.1.1 PBBs shall conform to the relevant requirements of EN 1915-1:2013, EN 1915-2:2001+A1:2009
and EN 1915-4:2004+A1:2009 unless otherwise specified in this document.
PBBs shall comply with the safety requirements and/or protective measures of this clause. In addition,
the PBBs shall be designed according to the principles of EN ISO 12100:2010 for relevant but not
significant hazards, which are not dealt with by this document.
5.1.2 Stability and strength calculations shall be carried out in accordance with
EN 1915-2:2001+A1:2009. Resonance shall be taken into account.

oSIST prEN 12312-4:2021
prEN 12312-4:2020 (E)
5.1.3 PBB shall be designed so that the stability and strength are ensured during intended use. The
basis for calculation shall be the most unfavourable combination of static and dynamic loads defined
according to EN 1915-2:2001+A1:2009 except as provided in 5.1.5 for the most unfavourable PBB
situation.
5.1.4 The lower parts of drive units of bridges with drive units shall be fitted with a device/devices to
prevent the running over of persons and contact with dangerous parts of machinery. This is achieved if
the protective device fulfils the following requirements:
a) the protective device shall prevent access to dangerous parts of the drive unit, e.g. wheels and belt
chain driven transmission;
b) the protective device shall be designed so as to prevent persons from reaching over the protective
device into the danger zone when the device is touching persons. This can be achieved e.g. if the
protective device has a minimum height above ground level of 1 000 mm;
c) the distance of the protective device from ground level shall not exceed 200 mm at all positions and
under all operating conditions;
d) the distance between protective device and parts of the wheels or drive unit shall be at least
200 mm;
e) the protective device shall be equipped with at least one trip (switch) bar at the bottom;
f) the bar shall detect the presence of a person in all directions of movement of the PBB and stop
movement before the danger zone is reached;
g) the safety related parts of the interlocking system shall achieve Performance Level “c” according to
EN ISO 13849-1:2015;
As an alternative to a physical barrier and trip bar, contactless protective devices may be used.
These devices shall meet the following requirements:
h) they shall ensure the detection of a person at a minimum distance of 0,5 m from any point of the
drive unit;
i) when moving at maximum speed in any direction, detection of a person shall stop the movement of
the PBB before contact is achieved between any point of the drive unit and the person;
j) access to dangerous parts of the drive unit shall be prevented unless other protective devices have
been fitted to achieve this;
k) detection and interlocking systems shall achieve Performance Level “d” according to
EN ISO 13849-1:2015.
5.1.5 As an exception from EN 1915-2:2001+A1:2009, 5.2.2.7, the following minimum wind speeds
shall be taken into account for stability and strength calculations:
a) PBB operation under rated load, fully erected and extended under the most unfavourable
combination of loads: 27,8 m/s (100 km/h, 54 kn);
b) PBB in parking position without rated load: 41,7 m/s (150 km/h, 80 kn).

NOTE As far as the aircraft is concerned, embarkation and disembarkation of passengers are allowed up to
30,6 m/s (110 km/h, 60 kn) or 33,2 m/s (120 km/h, 65 kn) depending on aircraft type. See ISO 11995:1996.
Where, based on local weather records, the wind speed defined in (b) can exceptionally be exceeded,
the PBB shall include provisions to tie it down to the ground up to a wind speed determined by the local
authorities.
Tie-down provisions should also be needed on the ground in the immediate vicinity of the PBB, with
their number, geometry and strength sufficient to guarantee PBB restraint up to the same wind speed.
5.1.6 Protrusions such as hydraulic tank, service access wheel trolley, and auxiliary equipment hang
on the PBB such as PCA, GPU, hose basket shall be covered with protective cushion and/or marked in
red and white to warn ground staff.
5.1.7 Drive unit in apron drive bridges shall be fitted with solid tyres. Pneumatic tyres are strictly
prohibited.
5.2 Controls, monitoring and warning devices
5.2.1 Positioning controls shall be provided to control the movement and speed of the PBB. The
control devices shall ensure that appropriate approach/docking speeds and direction of travel can be
maintained by the operator, e.g. marking of joy stick position, switch speed selector, separate control
devices. In automatic mode it shall not be possible to modify PBB speed or PBB movements.
Remote multi control panels shall control not more than one PBB simultaneously.
The communication channel for movement orders between the remote multi control panels and the
PBB shall achieve a performance level “D” according to EN ISO 13849-1:2015.
The remote multi control panels shall include an emergency stop button which, when the remote multi
control panel is connected to a PBB, stops it and achieves a performance level “D” according to
EN ISO 13849-1:2015.
5.2.2 An emergency stop shall be provided in each control panel. Emergency stops shall meet the
requirements of EN ISO 13850:2015, 4.1.4. The emergency stop shall not de-activate the braking
system. In addition, at least two emergency stops on opposite sides of the elevating system traverse in a
safe position and easily accessible from the apron, e.g. between 1,0 m and 1,5 m high and maximum
0,5 m from the outer contour shall be provided on the drive unit of apron-drive PBBs. In case of remote
multi control panel emergency stop shall act only on the selected PBB.
5.2.3 Emergency stops shall achieve a performance level according to EN ISO 13849-1:2015 equal or
greater than the most critical PLr provided in any safety control of the PBB.
5.2.4 For apron-drive PBBs, a monitoring system, e.g. camera, monitor display at the control panel
allowing visibility of the area surrounding the drive unit and bottom of the service access and
stabilizers, where installed, shall be provided.
