Foreword

This document EN 355:2002 has been pref.}ared by Technical Committee CENfTC .60 "ProtecUon against fall$
irom a height including working belts", the secretariat of which is held by DIN.

ThiS European Standard sha!l be given the status of a national standard, either b}1publir;ation of an identical text or
by endorsE::ment, at the latest by November 2002, 2nd conflicting national siandards shall be withdrawn at the latest
by November 2002.

This dccument supersedes EN 355: 1992. This new edition contains the old text of the standard and inccrporatcs
wme urgent amendments thc:t are irotended to give additional infonnation and clarify inconsistencies. A
comprehensive revision of the standard will follow at a later stage.

This document has been prepar~d under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex ZA, which is an intogral part of this document.

According to the CEN/CENELEC Internal Regulations, the national stal"\dards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, DE::nm8rX,Finl::md.
France, Germany, Greece, Icelano, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland aild the United Kingdom.

1 Scope f
This European Standard spAcifies the requirements. test mE:thods, marking, information supplied by the manufacturer
and packaging for energy absorbers. Energy absorhers confomling to this European Standard are used as elements
or compo!1~mts either integiated in a lanyard, an anchor line or a full body hamess or in combination with one of them.

Combinations of an energy absorber and d lanyard are s~b-systems constituting one o~ the fall arrest systems
covered by EN 363. when combined with a full body harness specified in EN 361.

Fall alTesters are specitied in EN 353-1, EN 353-2 and EN 36Q.

2 Normative ieferences

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 tefersr.ces, subsequent amendments to or rev:sions of any of these publications apply to this F.uropean
Standard only when incorporated in it by amendment or revision. For undated.references, the latest edition of the
publicationreferredto applies(includingamendments). .

3 Terms and definitions

For the purposes of this European Standard. the following terms and defii1itioi1s apply.

3.1
energy absorber
element or a component of a fall arrest system. which is designed to dissipate the kinetic energy developed during a
fall from a height [EN 363]

3.2
lanyard
connecting element or component of a fall arrest sys~em.A lanyard may be of synthetic fibre rope. wire rope, webbing
or chain [EN 363] . \.

3.3 \
length of energy absorber including a lanyard
totai length 4 in metres from one load bearing point to the other load bearing point. measured in an unloaded but taut (
condition of the energy absorber including lanyard [EN 363]
\
3.4 -
braking force
maximum force Fmax in kilonewtons, measured at the anchor point or the anchor line during the braking period of the
dynamic performance test fEN 363] f'

( arrest distance
vertical distance H in metr~s, meJsured at the nlobi:e 10nd bearing point of the connscting sub-~ystem from the initial
(
position (onset of the free fall) to the final position (equilibrium after the arrest), exciuding the displacements of the full
body harness and its attachment element [EN 363]

4 Requirements

4.1 Design and crgonomir.s

The general requirements for the design and ergonomics are specified in 4.1 of EN 363:2002.

4.2 Mat~rials and construction

\. .

If an energy absorber is incorporated in a lanyard (Le. the energy absorber cannot be removedwithout mutilating the
lanyc::rd,or without the use of a special dedicated tool),the lanyard shall conform to 4.2 and 4.3 of EN 354:2002.

Connectors for energy absorbers shall conform to EN 362.

4.3 Static preloading

When tested as describad in 5.1 the pe:manent extension caused by 3ctivation of the ellergy abs,:xber after
preloading with 2 kN shall nqt be greater than 50 mm.

4.4 Dynamic performance

vVhe!1tested as described in 5.2 with a rigid steel mass of 100 kg or a torso dummy of 100 kg mass, the braking force
Fmz:xshall not exceed 6 kN and the arrest distance H shall be H < 2 4 + 1,7f>m, dependingon the total length 4 of the
energy absorber inciuding lanyard. '
