(Main)Side curtains ventilation systems - Safety
Side curtains ventilation systems - Safety
This European standard specifies the standardisation of side curtain ventilation systems supplied for environmental control, installed on farm buildings, that use a barrier made from a flexible foil or fabric which move via a rolling or folding action, or rigid panels that slide; as far as safety aspects, performance and sustainebility issues are concerned. Included are machines that operate using the potential energy stored by the earlier application of human or animal force, such as stretched springs.

Introduction
In 2010, there was a fatal accident when a child of a farmer was trapped by an automatic stable display.
This accident happened both in the Netherlands and Belgium.
This accident triggered some Dutch experts to use the existing Dutch Technical Agreement NTA 8344:
2012 “Side curtains – Safety” for the development of the first European Standard “Side systems curtains
ventilation systems – Safety”.
This standard is a type-C standard as specified in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards are covered are indicated in the scope of this
standard. These hazards are specified to the Side curtains ventilation systems.
Where provisions of this type C are different from those which are stated by type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
In order to make the objective of this concept clear and eliminate uncertainties when reading it, the
following assumptions are made:
a) components without specific requirements are components
1) designed according to the common design and calculation methods, including all failure
mechanisms;
2) of a solid mechanical and electrical construction;
3) manufactured from sufficiently strong material with a suitable quality;
4) of which general electrical hazards are dealt with by application of the standards for electrical
installations, such as EN 60204-1:2018;
b) with the exception of the following provisions, is a mechanical supply built according to the
requirements of good craftsmanship and the requirements in this standard concept:
1) agreements between the manufacturer and the buyer about the special conditions of use, and
place where the screen is used in connection with health and safety;
2) the location of the installation will be suitable for this;
3) the place of installation will allow a safe use of the screen.
These assumptions do not limit the need for sufficient information in this concept standard before use.

5 Requirements
5.1 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 to the principles in EN ISO 12100:2010 for
relevant but not significant hazards which are not dealt with by this document.
The manufacturer shall perform a risk analyses, assessment and reduction process. For an example how
to perform such a process, see Annex E.
5.2 Mechanical requirements
5.2.1 General
Side curtain systems shall be designed and constructed so that they are capable of being installed,
maintained, repaired, used and dismantled in a safe manner.
5.2.2 Mechanical strength
The side curtain and its components, including its fixings for attachment to the building, shall be designed
so that, during normal operation, no part of the system, including the fixings, shall be permanently
deformed.
The side curtain shall be designed so that elastic deformations under operational forces or torques which
occur during normal use do not affect the function of the system.
The design shall be in accordance with recognized engineering stress/yield calculations or test methods
using adequate safety factors, see Table 1, taking into account the most unfavourable static and dynamic
forces occurring during the operating cycle or the use of the safety equipment within the side curtain.
Table 1 —Safety factors
Loading conditions Safety factors for calculation Safety factor for testing
purposes purposes
Stress due to differential 1,5 min breaking stress 1,0
pressure
Stress due to other loads 1,5 min breaking stress 1,0
(e.g. dead weight)
5.2.3 Resistance to wind load
The resistance to wind load of a side curtain is its capacity to withstand a specified differential wind
pressure.
NOTE The construction of the side curtain system depends on the pressure of a number of factors including,
e.g. the maximum wind speed anticipated in the area, the location, height, size and shape of the building, and the
position of the side curtain on the building.
When definite wind load classes or pressures are not stated by the specifier, side curtains shall be
designed in order to resist specified differential wind pressure, and shall be classified with the wind load
classes as specified in Annex F. See Figure F.1 for a typical wind map of Europe.
The requirements of this clause apply to the ability of the closed side curtain and not to their ability to be
opened or closed under wind load.

---------------------- Page: 12 ----------------------
SIST EN 17088:2021
EN 17088:2021 (E)
For correct operation of side curtains, the manufacturer shall state the maximum wind speed (within the
operating instructions, 5.9.4) where the system can be operated without risk of failure of the system.
The deflection of the curtain or other elements resulting from the differential pressure specified shall not
cause permanent deformations which will affect the functioning of the system or create any risk of
jamming.
5.2.4 Steel wire ropes, synthetic ropes, and straps
5.2.4.1 General
Steel wire ropes, synthetic ropes, and straps, etc. shall be suitable for the intended application with
regards to strength, durability and corrosion resistance.
For suspension elements, a single wire rope, synthetic rope, or strap, etc. can only be used if a failure of
the element will result in the curtain falling under gravity in a safe manner, i.e. the falling curtain will be
restrained in a controlled manner that would not expose people near to it to increased risk of crushing,
shearing, entanglement, drawing-in or trapping.
Where two or more suspension elements are used, it shall be ensured that the dead loads are shared in a
pre-determined way.
The guaranteed minimum breaking strength of such a suspension element determined by calculations of
the maximum load it has to support, multiplied by the safety factor (Table 1).
All such suspension elements shall have terminations a

Introduction
In 2010, an accident occurred in both the Netherlands and Belgium where the child of a farmer was trapped
by an automatic stable display and later died.
The Dutch Technical Agreement (NTA) 8344 came about upon the initiative of the Labour Inspectorate in the
Netherlands, and this standard was created building on the work carried out by the NTA.
This standard is a type-C standard as specified in EN ISO 12100.
The machinery concerned and the extent to which hazards are covered are indicated in the scope of this
standard. These hazards are specified to the Side curtains ventilation systems.
Where provisions of this type C are different from those which are stated by type A or B standards, the
provisions of this type C standard take precedence over the provisions of th
