5 Access, egress and doors
5.1 General
5.1.1 External steps and handrails
For external steps and handrails, EN 16116-1 shall apply.
5.1.2 Access and security

Access to the driver’s cab shall be from the exterior via a direct external door, and/or through a door from

an adjacent compartment or area behind the cab.

These doors shall be designed to have an operational envelope that does not conflict with the envelope

of another cab access door.

The driver’s cab and its access shall be designed so that the staff are able to prevent the cab being accessed

by non-authorized persons, whether the cab is occupied or not. This requirement is deemed to be fulfilled

by a locking system.

An emergency escape device shall permit to open any cab door from inside the cab without using any tool

or key.

Egress and access to the driver’s cab shall be possible without any energy supply.

5.1.3 Door handles

Driver’s cab internal door handles which are intended to be operated from a standing position shall be

located at a height between 820 mm and 1 200 mm (distance between the rotation point of the handle

and the cab floor). The recommended value for the height of the door handles is 850 mm.

5.1.4 Threshold
The height of door threshold shall not be more than:
— 20 mm from the floor adjacent to the door, for interior doors;
— 60 mm from the floor adjacent to the door, for exterior doors.
5.1.5 Ergonomics

For interior handles in regular use at least 40 mm clearance to surrounding surfaces shall be provided.

5.1.6 External doors

External cab doors when opened shall not infringe the intended maximal construction gauge defined from

gauge rules of the vehicle.

Driver’s cab external doors shall have a rectangular-like shape with a minimum unobstructed passage of

1 850 mm (height) × 550 mm (width) in accordance with Figure 1 (recommended minimum 1

900 mm × 600 mm).
NOTE The width value is based on anthropometric data (shoulder breadth).

Dimension r shall have a maximum value of 20 % of the width.

Cab external doors shall not open unintentionally. External cab doors should have at least two stable

positions: Fully opened and closed.
5.1.7 Internal doors giving access to the driver's cab

If internal doors lead directly to the passenger area, a device to observe this area from inside the cab shall

be provided, (e.g. by a spy hole or a transparent partition wall).

If direct view from passenger area into cab is possible, the driver should be able to prevent such view, e.g.

by blinds.

Internal doors shall have a rectangular-like minimum unobstructed passage height and width of 1

850 mm × 550 mm (recommended 1900 mm × 600 mm). Internal doors which are positioned left or

right of the vehicle's longitudinal axis and open in longitudinal direction may have a trapezium shaped

upper area with an angle of the top outer side (see Figure 2).

6 Floor and flooring
6.1 Floor surface criteria
Walkable flooring and steps shall be slip resistant.

This is deemed to be fulfilled by applying the requirements of CEN/TS 16165:2016, α (shod) ≥ 9°.

NOTE 1 CEN/TS 16165 is currently being converted into an EN.

For minimizing the tripping hazard, the walkable floor of the cab shall be level (with a tolerance of ± 2°).

Exceptions are allowed in the following areas:
— area up to a maximum of 25 mm from the walls;
— the space under the desk;
— the area adjacent to doors (if there is a step).
No irregularity on the walkable floor shall protrude by more than 2 mm.

Sealing plates of door frames (door thresholds) and maintenance openings are not considered as being a

floor irregularity, but shall not exceed 5 mm in height.

After application of a vertical load of 1300 N on a surface of 300 mm × 200 mm, no distortion of more

than 10 mm in direction of the load shall be observed in the walkable floor, over the whole flooring area.

This can be demonstrated by calculation or by test.

NOTE 2 No reference to EN 15663 is given, because the load is associated to the stiffness of the floor and not to

the load calculation for the vehicle.
6.2 Inclination, steps and slopes

The walkable floor of the driver's cab (access to the cab and foot rest excluded) shall be without any steps.

They are permitted between the cab and adjacent passenger area, as well as for accessing the cab from

the exterior.

Steps shall have a maximum height h of 250 mm and a depth of ≥ 210 mm. If more than one step is used

their height shall be identical. If there are two or more steps, a handhold (e.g. a handrail or a single handle)

should be provided.
7 Windows and glazing
7.1 Mechanical characteristics of glass
Glazing in cab windows shall be in accordance with EN 15152.
7.2 .Operation of opening windows
Three types of windows are considered in this standard:
— sliding horizontal;
— sliding vertical;
— hinged;

For all types of cab windows assembled but not mounted on the vehicle, the operating force shall not be

higher than 80 N (recommended value < 50 N).
---------------------- Page: 11 ----------------------
oSIST prEN 16186-8:2020
prEN 16186-8:2020 (E)

Vertically sliding windows shall not be capable of operating under their own weight.

8 Emergency
8.1 Driver's cab emergency exits
8.1.1 General

Driver's cab emergency exit and emergency exit clearance shall comply with the requirements of

EN 45545-4:2013, 4.3.1.2.
8.1.2 Minimum escape route

The escape route shall have a minimum clearance of height 1 850 mm x width 430 mm (if possible, width

should be 600 mm). This clearance is measured from the seat to the exit. The starting position is beside

the seat (driver has both feet on the cab floor and no part of the body still in touch with the seat). This

escape route and its floor shall be free of any obstruction. Steps are not considered as an obstruction.

8.1.3 Emergency exit opening

For opening emergency exits, no equipment shall be required with the exception of an emergency

hammer if a non-opening window is used as an emergency exit.
A cabinet below an emergency exit window is not considered as an obstruction.

Driver’s cabs should have at least one interior exit opening door. If there is any risk of obstruction

(baggage, passengers), the door should be of the swing type (opening outwards and/or inwards) or of

the sliding type.

The emergency escape device shall always function, irrespective of whether the door is unlocked or

locked.

In all positions of the door and the emergency escape device, there shall be a minimum clearance of

50 mm between the emergency escape device and surrounding objects in order to prevent a

contusion/injury risk for the hand.

When the door is open, the minimum escape route shall be respected, even when the emergency escape

device is in a normal (unpressed) position.
8.2 Emergency egress from seat
8.2.1 Seat design for escape

The driver's seat and the additional seat(s) in upright position shall not constitute an obstacle to escape

in case of emergency.

The driver's seat is not regarded as an obstacle, as long as the requirements of 5.4.2.2 can be achieved.

8.2.2 Escape from seat assessment criteria

Escape from the seat to a position beside the seat (both feet on the cab floor and no part of the body still

in touch with the seat) should be possible within 3 s after the requirement (e.g. a verbal command) to

leave the seat and it should be assessed with the following start conditions:
— at vehicle standstill;
— driver in driving and seated position (hand on the master controller);
— both feet of the driver on the foot rest;
---------------------- Page: 12 ----------------------
oSIST prEN 16186-8:2020
prEN 16186-8:2020 (E)
— by a small seated person with body height in the range of 1,55 m to 1,65 m;

— with arm rests, if provided, in their functional position at the beginning of assessment.

Then this test should be repeated for a tall seated person with a body height in the range of 1,81 m to

1,91 m.
9 Layout
9.1 General

The layout of the cab shall consider the anthropometric data as set out in prEN 16186-5:2019.

The cab should be designed in a way that it enables the driver to carry out his tasks efficiently and safely.

For all assessments, the driver is represented by the two driver dummies (see prEN 16186-5:2019).

The driver shall be able to operate all the driving controls (see prEN 16186-6:201X, definition 3.6) from

a normal driving position, according to the comfort angles defined in 6.3. The driver shall be able to

respect all the visibility requirements defined in prEN 16186-5:2019.

The anthropometric data defined in prEN 16186-5:2019 shall be used to define the arrangement of the

driver's seat to allow driving from a seated position.
9.2 Prevention of occupational injuries
9.2.1 General

In the accessible areas of the driver's cab, the internal fittings shall be designed to prevent occupational

injuries, e.g. by sharp edges, moving parts, protruding objects, etc.

Only exposed rigid edges which can be contacted by a 100 mm diameter sphere shall be considered.

Edges of components which are not directly exposed (for example sheet metal fabrications beneath

seats) shall be de-burred or chamfered to give smooth edge profiles.
9.2.2 Exposed edges

In differentiating between an external and an internal edge, where a panel edge fits up against

another element to form astep or a recess that edge shall be considered to be internal (for example

where rebated panel joints are used).

A rigid edge shall be considered to be one using material with a Shore A hardness greater than 50.

With the exception of glass edges, in the accessible areas of the driver's cab, there shall be no exposed

rigid external edges where the predominant radii (i.e. ignoring transition and blending radii) are less

than 3 mm or without a chamfer of at least 3 mm × 3 mm.

For exposed rigid external edges, where the edge projects not more than 3,2 mm from the adjacent

surfaces, the requirements for minimum radii shall not apply, provided that the height of the projection

is not more than half its width and its edges are blunted.

All exposed glass edges shall be arrissed or bevelled to give smooth edge profiles.

There is no restriction on the use of alternatives to the specified or recommended dimensions

where evidence of their suitability can be presented in terms of injury potential. The specified

dimensions may be used as the basis for comparison.
9.2.3 Formulae for exposed edge radii for obtuse included angles

Requirements or recommendations for minimum edge radii assume 90 degree external corners. In cases

where a minimum radius is specified and the included angle between surfaces is greater than 90 degrees,

---------------------- Page: 13 ----------------------
oSIST prEN 16186-8:2020

the minimum radius may be reduced according the method shown in Figure 3 and taking values

according to Table 1.
Key
α included angle between surfaces
Figure 3 — Examples of external edge radii for obtuse included angles

For external edges or corners which are partially exposed, only the parts of the edge surface that can be

contacted by a 100 mm diameter sphere are considered. The effective included angle for determining the

minimum edge radius shall be determined with a 100 mm diameter sphere positioned on the

adjacent lower surface or surfaces and taking the included angle between the tangent to the sphere at

the point of contact with the edge of the upper surface assuming there is no radius (See Figure 4).

NOTE Upper and lower surfaces are relative to the assumed direction of approach by the sphere.
