Foreword<\/strong><\/h4>\n\n

This document EN 13374:2004 has been prepared by Technical Committee CEN\/TC 53 \u201cTemporary works
equipment\u201d, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by the publication of an identical
text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn
at the latest by December 2004.
The standard is intended to cover equipment for temporary edge protection<\/a><\/span> appropriate for use throughout Europe.
Annex A is normative. Annex B is informative.
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, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, and the United Kingdom<\/p>\n\n

Introduction <\/strong><\/h4>\n\n

Temporary edge protection systems are used in construction work, primarily to prevent persons and objects from falling to a lower level from roofs<\/a><\/span>, edges, stairs<\/a><\/span>, and other areas where protection is required. In several European countries temporary edge protection, or other types of fall protection<\/a><\/span> devices, are required 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 situations also act as a handrail<\/a><\/span> 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 to 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.<\/p>\n\n

1. Scope<\/h4>\n\n

This European Standard specifies the requirements and test methods for temporary edge protection systems for use during the construction or maintenance of buildings and other structures.
This standard applies to edge protection systems for flat and inclined surfaces and specifies the requirements for three classes of temporary edge protection.
For edge protection systems with an arrest function (e.g. falling or sliding down a sloping roof) this standard specifies requirements for energy absorption.
This standard includes edge protection systems, some of which are fixed to the structure, and others, which rely on gravity and friction on flat surfaces.
This standard does not provide requirements for edge protection systems intended for:
\uf8e7 Protection against impact from vehicles or from other mobile equipment,
\uf8e7 Protection from sliding down of bulk loose materials, snow, etc.,
\uf8e7 Protection of the general public from falling.
This standard does not apply to side protection systems on scaffolds.<\/p>\n\n

2. Normative references<\/h4>\n\n

This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies (including amendments).

<\/p>\n

\u00a0<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

6.3.2 Loads parallel to the guardrail
Each edge protection and each of its components shall severally be capable of withstanding a horizontal
force of 0,2 kNat the most onerous point, see Figure 7.<\/p>\n

<\/p>\n

\"\"<\/figure>\n

<\/p>\n

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 = \u03a3 ( cf,i \u00b7 qi \u00b7 Ai )<\/p>\n

<\/p>\n

where Fw is the resulting wind force
cf,i is the aerodynamic force coefficient for the edge protection components i (cf0 may be used uncorrected)
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<\/p>\n

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.<\/p>\n

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 approximately 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:
\uf8e7 The horizontal loads according to cl. 6.3.1;
\uf8e7 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 deflection of the whole assembled system where either the force FT1 or FT2 is applied, at the most unfavorable 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 component 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 unfavorable position of the edge protection system in a downward direction within a sector of \u00b1 10\u00b0 from the vertical.<\/p>\n

<\/p>\n

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 the kinetic energy of 1100 J anywhere along with the protection 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 relevant value of the minimum deflection is maybe 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 with 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 \u03b4min (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 of 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 requirements 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.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

7.4.2.4 Evaluation of test records
The deflection at the maximum test load, \u03b4, shall be adjusted, using statistical methods, which comply with
EN 12811-3.
7.4.3 Test for strength
7.4.3.1 Procedure for strength test
The loads shall be applied at the most adverse positions.
Establish the datum position of the edge protection, \u03b41.
The system shall be loaded in ten regular increments up to the maximum test load, Fmax (= \u03b3M x \u03b3F x QK),
where \u03b3M and \u03b3F are partial safety factors, see 6.2.1, and QK is the characteristic load for the case being considered, see 6.3.1.
This maximum test load shall be held for one minute. The instantaneous deflection of the edge protection, \u03b42
at this maximum load shall be measured.
During this period of maximum load, there should be no identifiable yielding, fracture, or separation of any part of the assembly.
The test load shall be removed and the residual deformation on the removal of the test load shall be measured.
This residual deflection shall not exceed 10 % of the deflection at maximum load.
The system should then be loaded in the same increments as up to the ultimate load, Ru, where there is an identifiable failure in either the system as a whole or in one of its component parts.<\/p>\n\n

7.4.3.2 Records
Record the following:
a) datum position deflection \u03b41,
b) the instantaneous deflection at maximum load \u03b42.;
c) The residual deflection \u03b43;
d) The ultimate load RU;
e) Any observations relating to yielding, fracture, or separation of any part of the test assembly.<\/p>\n\n

7.4.3.3 Evaluation of recorded results
Calculate the maximum deflection, \u03b4max = \u03b42 – \u03b41
The ultimate load RU shall be adjusted, using statistical methods, which comply with EN 12811-3.

<\/p>\n

Annex A
(normative)
Test to establish the coefficient of friction
A.1 Principle of the Test
A horizontal force is applied to a specified weight resting on a level platform \u2013 see Figure A.1. The applied
force is steadily increased until the specified weight starts to move. The horizontal force required to initiate
movement is used in calculating the coefficient of static friction between the weight and the level platform.
A.2 Apparatus
A plate A: 300 mm long \u00d7 100 mm wide and with the necessary thickness to be representative of the material
to be tested.
A block of mass 50 kg which can be supported on the plate A.
A platform surfaced with the material B with the necessary thickness to be representative of the material to be
tested.
A.3 Procedure
Support the platform surfaced with B horizontally and level to within \u00b1 0,5 degrees. Prevent movement of the
platform in the direction of the applied force. Place the plate A on the platform and load it with the 50 kg block.
Apply the horizontal force F to the 50 kg block in increments of 50 N (see Figure A.1) as close as possible to
the underside of the plate A.
A.4 Test records
Record the force at which the specified weight moves at least 10 mm along the platform.
A.5 Evaluation of test records
The coefficient of static friction, \u00b5, shall be calculated for each test using equation [A.1] given below:
Coefficient of static friction,
\u00b5 = F \/ (M + m) \u00d7 g (A.1)
where
F = force in Newton
M = mass 50 kg
m = mass of the plate
g = 9,81 ms\u20132
Calculate the arithmetic average of \u00b5 from a minimum of four tests. This average value shall be taken as the
characteristic coefficient of static friction, \u00b5, between the plate A and the surface B.<\/p>\n

<\/p>\n

<\/p>\n

Annex B
(informative)
Appropriate classes for the use at different inclinations and falling
heights
The edge protection specified in this standard is for three different classes. This annex gives advice on which
class to use depending on the angle of the working surface from the horizontal and the possible falling height.
Class A should not be used if the angle of the working surface is more than 10o.
Class B may be used if the angle is less than:
\uf8e7 30\u00b0 without limitation of the falling height, or;
\uf8e7 60\u00b0 and the falling height is less than 2 m.
Class C may be used if the angle is between:
\uf8e7 30\u00b0 and 45\u00b0 without limitation of the falling height, or;
\uf8e7 45\u00b0 and 60\u00b0 and the falling height is less than 5 m.
If the angle is more than 60\u00b0 or more than 45\u00b0 and the falling height is more than 5 m, edge protection systems are not appropriate as protection. At greater falling heights the system can be placed higher on the sloping area, for example, every 2 m and 5 m of falling height for system class B and C respectively.<\/p>\n
