Foreword
This document (EN 1492-4:2004) has been prepared by Technical Committee CEN/TC 168 “Chains, ropes,
webbing, slings and accessories - Safety”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by 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text or by endorsement, at the latest by December 2004 and conflicting national standards shall be withdrawn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.
This document has been prepared 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 integral part of this document.
This European Standard is one of a series of standards related to safety for textile slings as listed below:
Part 1: Specification for flat woven webbing slings, made of man-made fibres, for general purpose use
Part 2: Specification for roundslings, made of man-made fibres, for general purpose
Part 4: Specification for lifting slings for general service made from natural and man-made fibre rope

This is the first edition of this part of EN 1492.
In this standard:
Annex A is normative, and gives the requirements for information on use and maintenance to be provided by
the manufacturer with fibre rope slings conforming to this standard.
Annex B is informative, and gives the working load limits for different configurations and types of material for
fibre rope slings to this standard.
Annex C is informative, and provides some detailed information for use and maintenance which may be
appropriate in compiling the information in accordance with annex A.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,

and United Kingdom.
Introduction
This European Standard has been prepared to be a harmonized standard providing one means of complying
with the essential safety requirements of the Machinery Directive and associated EFTA regulations.
This European Standard is a type C standard as specified in EN ISO 12100-2. The lifting accessories
concerned and the extent to which hazards are covered is indicated in the scope of this standard.
NOTE For hazards that are not covered by this standard, lifting accessories should be in accordance with EN ISO
12100-2.
1 Scope
This European Standard specifies the requirements related to safety, including methods of rating and testing
single-, two-, three-, four-leg and endless slings, with or without fittings, made of sisal, hemp and manila 3-
and 4-strand laid construction natural fibre ropes and polyamide, polyester and polypropylene 3- and 4-strand
laid construction and 8-strand plaited construction man-made fibre ropes having a reference number in the
range of 16 to 48 inclusive.
The fibre rope slings covered by this part of EN 1492 are intended for general purpose lifting operations, i.e.
when used for lifting objects, materials or goods which require no deviations from the requirements, safety
factors or working load limits specified. Lifting operations not covered by this standard would include the lifting
of persons, potentially dangerous materials such as molten metal and acids, glass sheets, fissile materials,
nuclear reactors and where special conditions apply.
Fibre rope slings conforming to this European Standard are suitable for use and storage in the following
temperature ranges:
a) polyester and polyamide -40°C to 100°C,
b) manila, sisal, hemp and polypropylene -40°C to 80°C.
This European Standard does not apply to fibre rope sling assemblies rated by the trigonometric method.
This European Standard deals with the technical requirements to minimize the hazards listed in clause 4
which can arise during the use of fibre rope slings when carried out in accordance with the instructions and
specification given by the manufacturer or authorized representative.
2 Normative references
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).

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN ISO 1968:2004 and the
following apply.
3.1
fibre rope sling
flexible sling comprising one or more parts of identical fibre rope, terminating in spliced eyes with or without
thimbles and fittings, or in the case of an endless sling, joined to itself with a splice

3.2
multi-leg sling
fibre rope sling assembly, consisting of two, three or four identical legs attached to a master link

3.3
splice
specified method of laying the tail end strands of the rope into the strands of the standing part of the rope to
form an eye or join the ends of the rope together

3.4
soft eye
eye made by forming the end of the rope into a loop and by splicing the free end to the standing part

3.5
thimbled or hard eye
spliced eye containing a rigid thimble
3.6
thimble
rigid, shaped component for insertion into an eye for the purpose of protecting the eye from contact damage,
abrasion and deformation, see Figure 1

a) Heart shaped b) Reeving
Figure 1 — Thimble
3.7
fitting
loadbearing metal component, designed to be fitted and supplied as part of the sling, so as to permit the sling
to be attached to other lifting accessories or connected to the load
NOTE Thimbles are not included within the term ‘fitting’.
3.8
master link
link, or link assembly, forming the upper terminal fitting of a multi-leg sling assembly by means of which the
sling assembly is attached to the hook of a crane, other lifting machine or accessory

3.9
reference number
number quoted in documentation which specifies the mass/metre, breaking force and other parameters of the
fibre rope. The reference number corresponds to the approximate diameter in millimetres; minimum breaking
force in daN.
NOTE See EN 696, 697, 698, 699 and 1261.
3.10
nominal diameter
specified diameter of the rope, which is usually used as the reference value for a given product

3.11
nominal length
specified length of the sling, inclusive of fittings, from bearing point to bearing point
NOTE See figures 2 to 5.
3.12
effective working length (EWL)
actual finished length of the fibre rope sling, inclusive of fittings, from bearing point to bearing point
3.13
coefficient of utilization
ratio of the specified tensile strength of the rope to the WLL of the single part of spliced rope, taking into
account the acceleration due to gravity (9,80665 m/s ) and is equal to 7
NOTE 1 Fittings may have a different coefficient of utilization from that of the rope to which they are connected.
NOTE 2 This term has the same meaning as the term ‘working coefficient’ used in the Machinery Directive.
3.14
Assembly Factor (A)
factor used in the calculation of the WLL of the sling assembly that takes into account the assembly of the
sling, the number of legs and the inclination angles (β), see Figure 10

3.15
Mode Factor (M)
factor to be applied by the user to the WLL of a fibre rope sling in order to arrive at the maximum load that
maybe lifted for a given mode of use
3.16
Working load limit (WLL)
maximum mass which a fibre rope sling is designed to sustain in straight pull or at the rated angle, in general
service
