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.
1 Scope

Straps and belt
QUESTION
What is the difference between straps and belt?
Is there a normative reference?
INTERPRETATION
The section is pointing out the hazard zone of the carrying element independent of the specific
technology used. The non-exhaustive list should provide examples for commonly used materials
in the industry.
The main difference between strap and a belt is:
- a belt (band of rubber or metallic) is on its driven side, flat
- a strap (flat woven textile webbing) can have on its driven side teeth
It is up to the manufacturer to evaluate the applicable standard for their equipment / component.
Examples of bibliographic references may include:
• EN ISO 283:2015 Textile conveyor belts – Full thickness tensile strength, elongation at break
and elongation at the reference load – Test method (ISO 283:2015)

Area Concept
QUESTION
If area concept isn´t used, what is the consequence?
INTERPRETATION
No Area Concept would mean from you have only danger area and working place, no exceptions are
allowed for traffic and restricted area via the standard. You are supposed to make a risk assessment
and try to make exceptions from danger area and working place for every detail, means a lot of work
and in relation to the standard, the solution needs to be proven.
Using some of the types of areas defined in EN 619:2022 or using the area concept globally, are not
compulsory.
Other standards give examples, placement of emergency stops, fire protection, escape paths and are
using some kind of concept to define the sufficient method of protection for a certain situation.
See for example the former edition EN 619:2002 + A1:2010, it was already defining requirements
based on an area concept.

5.1.1.1 General
In the working and traffic area danger zones between powered and fixed components of horizontal
or points, feed points, diverting points, horizontal and vertical transfer devices and gates shall be
safeguarded. This shall be achieved e.g. by providing a continuous maximum gap of 5 mm between
moving and fixed components (see Figure D.1).
Alternatively, the danger zones shall be safeguarded e.g. by fences (wire mesh in accordance with EN
294), interlocking doors or gates or trip devices (photo electric devices, pressure sensitive mats). If the
load creates a danger zone, its most unfavourable position shall be taken into account.

Clearance shearing/ crushing points
QUESTION
For clearances a from 120 mm to below 500 mm between conveyed unit loads and fixed adjacent
objects or guards crushing and shearing points are intended to be prevented, …
Is this Key “a” in figure C.19 and C.20?
INTERPRETATION
Since in figures C.19 and C.20 key “a” is related to the clearance between moving load and fixed
nd
part of the installation (guard, any fixed adjacent object), subclause 4.2.1.1.4 (2 paragraph)
defines the applicable requirement when this value “a” varies from 120 mm to below 500 mm.
Currently in figure C.19 key a shows the clearance between the outside of the fence and the side
channel of the conveyor. This has been noted by the working group and will be fixed for the
ongoing revision. The key shall indicate the clearance between the moving load and fixed guard as
depicted in C.20.

QUESTION
7) the access over and between gravity roller conveyors is considered to be prevented, if each of
the following requirements are met over the length “a” of at least 2,0 m (independent from the
height of the conveyor) (see Figure D.10):
b) the frame width “a” of the conveyor shall not exceed 40 mm or the possibility of walking on the
frame of the conveyor is minimized by the design of its surface, e.g. by profiles according 4.2.10
(see Figure D.1);
Is “a” in 7) and 7b) the same? If not, it is not so good to have the same letter for different values.
INTERPRETATION
In 4.2.8 indent 7), the value “a” refers to the length of the separating plate (see Figure D9 [top view]
and not as mentioned by error Figure D10 [front view] that has no key “a”).
In 4.2.8 indent 7) item b) the value “a” refers to the width of the frame (see Figure D1).
The mentioned issue will be raised in CEN/TC 148 /WG2 and will be taken into consideration for
future changes.

Why is there “In addition” instead of “alternative” or “or”? This can be read that it must be used additively.
INTERPRETATION
nd
The standard in 4.2.9 in its 2 section, defines dedicated requirements for roller conveyors,
carrying chain conveyors and twin belt conveyors. These requirements are partially based on
those already defined in 4.2.8.
WG2 intended to provide an alternative access not an additional requirement. WG2 will take the
comment into consideration to improve the wording in the future.

Crushing and shearing points between roller conveyors and
conveyed unit loads
QUESTION
At workplaces, crushing and shearing points on roller conveyors . must be secured. In traffic and
maintenance areas the safeguarding can be omitted.
Why could the safeguarding be omitted in the maintenance area?
INTERPRETATION
“Safeguarding can be omitted” only refers to requirements raised in chapter 4.20.2.1.
The standard does not specify a maintenance area because it may appear in different ways
dependent on the system elements or conveyor types. (e.g. a parking position on a self-propelled
overhead conveyor or a temporary maintenance area for a pallet chain conveyor line.)
Note: The next part on the answer assumes the question is referring to restricted areas as defined
instead of the mentioned maintenance area.
The introduced area concept distinguishes between working place (see 3.1.1), traffic area (see
3.1.2) and restricted area (see 3.1.3). Whilst the restricted area may only be infrequently accessed
by qualified personnel the workplace is frequently accessed by operators working along the
installation. The access to restricted areas may be designed according to chapter 4.1.2, 4.2.8 or
4.2.9.
Additional requirements for specific conveyor types are outlined in subsequent chapters.

Safety distances for overhead conveyors
QUESTION
The overhead conveyors shall be stopped so as to leave a distance “a” in the direction of travel
between two mobile units and/or their loads of at least 0,5 m up to a height “b” of 2,5 m above the
standing surface of persons (see Figure C.3). Swinging of the mobile units shall be taken into
account.
— “a” = 0,5 m, above parts of structures or machines and above other traffic and transport means
which move under overhead conveyors where persons can be injured by crushing hazards (see
Figure C.4).
Why does the text say for distance a at least 0,5 m and the mirror line say “a” = 0,5 m?
INTERPRETATION
The current wording of standard clearly defines, in both requirements in 4.20.8.2, a value for the
distance of at least 0.5m:
4.20.8.2 Safety distances for overhead conveyors
A lateral minimum distance “a” of 0,5 m up to a height b of 2,5 m above the standing surface of persons
shall be maintained between the conveyors, their loads and fixed objects in the surroundings (see
Figure C.2). Where the lateral distance to fixed objects e.g. columns of the building is less than 0,5 m
additional measures shall be fitted, e.g. sloping plates or protective devices.
The overhead conveyors shall be stopped so as to leave a distance “a” in the direction of travel
between two mobile units and/or their loads of at least 0,5 m up to a height “b” of 2,5 m above the
standing surface of persons (see Figure C.3). Swinging of the mobile units shall be taken into account.
The following vertical safety distances under overhead conveyors, including the suspended conveyed
materials, down to the floor or up to fixed objects shall be maintained at least:
— “c” = 0,5 m between the floor and mobile units (see Figure C.3);
— “a” = 0,5 m, above parts of structures or machines and above other traffic and transport means
which move under overhead conveyors where persons can be injured by crushing hazards (see Figure
C.4).
In both cases, the minimum safety distance of 500mm (consideration body part: body) shall be
maintained to avoid crushing of body parts (EN ISO 13854:2019 - 4.2. Values).
Adjacent objects are described in 4.2.1.1.4.

Strength of ropes, chains and belts for lifting purposes
QUESTION
Both chapter has the same text. What is the difference?
This section can be interpreted as requiring 8 times the breaking force for each rope, in which case
it would not be the same as section 4.2.4.2.
Definitions of safety gear, safety brake, safety brake, transmission elements are missing.
Figures C.27/ C.28 are not clearly comprehensible
The value was set down from 10, why?
Insert example calculation, many people do not know how to calculate the redundancy.
4.2.4.2
5000 kg load on belts, 4 belts
5000/4 = 1250 kg load per belt
1250 kg *5 = 6250 kg = 1 x 5 times the safety of one pair of belts
1250 * 2.5 = 3125 kg = 1 * 2.5 times safety with belts
4.20.8.4.2
Each suspension point with 2 independent belts/wire ropes/chains, breaking force for ropes 8
times the maximum static force OR
Independent safety gear and overspeed governor according to EN 81-20
INTERPRETATION
Chapter 4.2.4.2 states general requirements for lifting elements on all type of machines covered
by EN619. Chapter 4.20.8.4.2 emphasizes the requirements for overhead conveyors where the risk
is generally more prominent.
Figures C.27 and C.28 are simplified drive concepts common in vertical transfer devices in
intralogistics. The pictures are required to be non-brand or manufacturer related and therefore
are intentionally abstract.
The changes in EN 619:2022 to the safety factor of carrying elements stem from a harmonization
with requirements stated in EN 528:2021+A1:2022.
The reduction of the safety factor of the carrying element from 10 to 8 has been agreed on since
the connection element from the carrying element to the rope termination (see
EN528:2021+A1:2022 Chapter 4.4.5.2.7) was always required to withstand 80% of the tensile
strength of the carrying element.
With the change the requirement is intended to be the same between anchor points and tensile
strength of the carrying element.
Calculation examples are not provided by CEN TC 148 at the current revision but will be taken as
a note for future publications.

Transfer cars with short distance picking places
QUESTION
What if the pallet is not completely filled? Then you still enter the danger zone.
INTERPRETATION
This standard based on the state of the Art and on the consensus reached by the experts which
aims to address the common hazards for the product group on a general base. If additional hazards
are present in the specific application / situations the manufacturer needs to address these
additional hazards.
The measures proposed in chapter 4.20.9.3.3 considered the situation. Access into the dangerous
area is only permitted when all hazardous movement has stopped aligning with chapter 4.2.1.1.2.
The standard does not offer the presumption of completeness as stated in chapter 4.1.
4.1 General
“Machinery shall comply with the safety requirements and/or protective/risk reduction measures of
this clause. In addition, the machine shall be designed according the principles of EN ISO
12100:2010 for relevant but not significant hazards which are not dealt with by this document.”

What is the definition of intermediate levels?
INTERPRETATION
An intermediate level refers to every level between the highest and lowest level of the vertical
transfer device providing inbound/outbound for loads and additional maintenance point. This
typically refers to all levels, except the floor level, with a pick and drop location but may include
additional points based on the manufacturers guidance for maintenance.
The standard provides clarifications about floor level (see example in Figure D.12) and the upper
level (see example in Figure D.13).

Preventing access from the restricted area to the danger area
of a vertical transfer device
QUESTION
Access from restricted area to danger area shall be safeguarded according either to 4.2.8 or 4.2.9
(see Figure D.13).
Why can you choose? A lifting carriage is a danger area, why is it allowed to safe it as a restricted
area?
INTERPRETATION
Chapter 4.20.11.2 provides requirements for the transitions from traffic area to the danger area of
vertical transfer devices. Chapter 4.20.11.3 provides requirements for the transition from
restricted areas to the danger area of vertical transfer devices.
Why can we choose between safeguarding according to chapter 4.2.8 or 4.2.9?
We are coming from restricted area; here trained operators are aware of potential dangers.
Untrained personnel present in the traffic areas are required to transition protected intersections
designed according to chapter 4.2.8 or 4.2.9 twice. A single malicious transition of these interfaces
is already considered to be malicious intent.
What is the reason?
Chapter 4.20.11 provides measures for vertical lifts on ground floor or mezzanines. Additional
measures include a door in a visible area to safely enter the machine. Therefore, a misuse to
circumvent safety provisions across the conveyor are non-incentivised

INTERPRETATION
The standard in 4.20.11.2 “Preventing access from the working place and traffic area to the danger
area of vertical transfer devices” defines the following requirement “Access from the working
place and traffic area to the danger area shall be safeguarded according to 4.2.8 (see Figure D.12).”
The standard in 4.2.8 lists possible additional requirements like:
The one described into indent 1) “sensitive protective devices according to 4.2.1.1.3 are provided;
the activation of the protective device shall stop the dangerous movement.”
The one described into indent 4) “conveying height is 1,0 m high or more (see Figure D.17);
conveyors and any other installation (e.g. guards) are designed to prevent people climbing to the
aperture. The next crossover passageway shall be at least 2,0 m away from the aperture for
conveyors designed to prevent walking on as described in the second paragraph of 4.2.9. For other
conveyors the distance shall be at least 5,0 m;”
Therefore, Figure D.12 aims to provide clarification for a specific configuration of this subclause
of the installation where the conveyor heigh is lower than 1 m and the preventing measure is an
electro-sensitive protective equipment (ESPE) that stops the movement when actuated.
