According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Cyprus, Den-mark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxem-bourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,

EN 13374:2004 (E) 4 Introduction Temporary edge protection systems are used in construction work, primarily to prevent persons and objects from falling to a lower level from roofs, edges, stairs and other areas where protection is required. In several European countries temporary edge protection, or other types of fall protection devices, are re-quired when the fall height is more than 2 m. In contrast to being secured by a lanyard, greater mobility in the working area is provided when edge protection is in place. The temporary edge protection can in some situa-tions also act as a handrail for people to hold onto when working or walking close to an edge.
While this standard also includes requirements to protect people from falling objects, e.g. by the provision of toeboards, there could be circumstances where this is insufficient and additional measures, which are beyond the scope of this document, will need to be taken. Classes specified in this standard are intended to cater for the varied requirements appropriate for different uses. It is important that the structure to which temporary edge protection is attached can support the forces that the system is designed for. SIST EN 13374:2004

All loads specified in this standard shall be treated as characteristic loads. NOTE Characteristic loads means that partial safety factors shall be applied. SIST EN 13374:2004
EN 13374:2004 (E) 13 The edge protection system, as well as each component, shall fulfil the individual load requirements sepa-rately. When it is not possible
to verify the design assumption adequately by calculation, confirmation testing shall be carried out. Design shall be carried out in accordance with the European Standards for structural engineering. The
stan-dards include: For steel: ENV 1993-1-1 For aluminium: ENV 1999-1-1 For timber: ENV 1995-1-1 For design: EN1990 If there are conflicts between provisions in this standard and other standards, e.g. ENVs, then the provisions in this standard shall have precedence. When using ENV 1995-1-1 the following characteristics shall be used. Load duration: instantaneous for accidental load; short-term duration for other loads. Service class: class 2. Modulus of elasticity: Emean for serviceability limit state; E0,05 for ultimate limit state. 6.2 Partial safety factors 6.2.1 Ultimate limit state For the ultimate limit state, partial safety factors shall be: γF = 0,9 for favourable loads, for example counterweight when calculating the stability of counterweighted protection; γF = 1,5 for all permanent and variable loads; γM = 1,1 for ductile metallic materials ( some ductility limits are given in EN 12811-2); γM = 1,25 for brittle metallic materials; γM = 1,3 for timber. SIST EN 13374:2004
EN 13374:2004 (E) 14 6.2.2 Serviceability limit state For serviceability limit state, partial safety factors shall be: γF = 1,0 for all loads; γM = 1,0 for all materials. 6.2.3 Limit state for accidental actions For the accidental actions given in 6.3.5, partial safety factors shall be:

and each of its components shall severally be capable of

Figure 7 — Loads parallel to the guardrail 6.3.3 Wind forces 6.3.3.1 General The edge protection system shall withstand the force from wind load.
6.3.3.2 Evaluating wind forces
Wind forces, Fw, shall be calculated by assuming a wind velocity pressure to be applied on an effective area of the edge protection system, which is in general the projected area in the wind direction, not taking shielding into account. It shall be determined as follows: Fw = Σ ( cf,i · qi · Ai ) SIST EN 13374:2004
EN 13374:2004 (E) 16 where Fw is the resulting wind force cf,i is the aerodynamic force coefficient for the edge protection components i (cf0 may be used uncor-rected)
cf0
is the force coefficient of a component with infinite slenderness ratio qi is the wind velocity pressure acting on the edge protection components i and shall be taken as 0,6 kN/m2
Ai is the reference area of the edge protection components
NOTE 1 The aerodynamic force coefficient cf,i appropriate to the cross section of the edge protection components in question is given in ENV 1991-2-4.
For any cross-sections, not included in ENV 1991-2-4, the aerodynamic force coefficient may not be assumed to be less than 2,0, unless it has been established by testing. NOTE 2 0,6 kN/m2 covers most wind conditions in Europe. More onerous conditions may occur. The wind velocity pressure is based upon 40 meters height and an exposure period of 6 months and represents a wind speed of approxi-mately 30 m/s. Where wind is shown to be the governing load case, i.e. its effects are greater than the effect of the 0,3 kN specified, the edge protection shall be shown to withstand the wind load by calculation. 6.3.4 Load combinations Load combinations, consisting of the following loads shall be designed for: The horizontal loads according to cl. 6.3.1; Wind load according to cl. 6.3.3, where qi may be taken to the value of 0,2 kN/m2. Only the ultimate limit state has to be considered. 6.3.5 Serviceability limit state The elastic deflection shall not be greater than 55 mm. The elastic deflection specified is defined as the de-flection of the whole assembled system where either the force FT1 or FT2 is applied, at the most unfavourable position, see Figure 6. 6.3.6 Accidental loading Any guardrail or intermediate guardrail or toeboard, regardless of its method of support, shall be capable of resisting a downwards point load FD = 1,25 kN on a length of 100 mm. This also applies to any other compo-nent of the edge protection systems, such as a fencing structure, which has gaps in excess of 100 mm width, see Figure 6. This load shall be applied in the most unfavourable position of the edge protection system in a downward di-rection within a sector of ± 10° from the vertical. SIST EN 13374:2004
EN 13374:2004 (E) 17 6.4 Dynamic load
6.4.1 Edge protection system class A This standard does not specify any dynamic loading . 6.4.2 Edge protection system class B Class B edge protection shall be capable of absorbing a kinetic energy of 1100 J anywhere along the protec-tion up to a height of 200 mm above the working surface and 500 J at all higher parts. The dynamic test specified in 7.5.2.1 shall be carried out. For class B edge protection to comply with the dynamic strength requirements of this standard, the sphericonical bag shall be arrested by the edge protection.
The system does not need to be serviceable after the test. NOTE The intention is to consider a requirement for minimum deflection in a future revision of this standard. A rele-vant value of the minimum deflection may be 100 mm. 6.4.3 Edge protection system class C Class C edge protection shall be capable of absorbing 2200 J of kinetic energy anywhere along the protection up to a height of 200 mm above the working surface. The dynamic load test specified in 7.5.2.2 shall be carried out.
For class C edge protection to comply with the requirements of this standard: a) the cylindrical impactor shall not pass through the edge protection; and
b) the minimum deflection between the posts δmin (at a level 200 mm above the working surface) shall be 200 mm, at the moment when this energy has been absorbed.
The system does not need to be serviceable after the test. NOTE The intention is that the deflection requirement of a minimum 200 mm should be applied to every part of the system (at a level 200 mm above the bottom), once a satisfactory practical solution is available, i. e. also to apply the re-quirements to the supports. At the time of writing this standard the state-of-the-art means that it is not practicable to apply the deflection requirement to the posts or close by. 7
Test methods 7.1 General The test shall be carried out in accordance with the requirements in clause 7 of this standard, and additionally relevant European Standards shall be used. Unless otherwise indicated in the following, testing shall be con-ducted by way of visual examination and measurement.
