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.
The other parts of this European Standard are:
Part 1 Slings for general lifting service

Introduction
This Part of the standard has been prepared to provide a means of complying with the essential safety
requirements of the Machinery Directive and associated EFTA regulations.
Purchasers are advised to specify in their purchasing contract that the supplier operates a quality management
system applicable to this standard (e.g. ISO EN 9001) to ensure that products claimed to comply consistently
achieve the required level of quality.
The coefficient of utilization (Z ) used in this standard for slings with a diameter greater than 60 mm is lower than
p
that normally used for general service wire rope slings. This is justified for the following reasons.
a) Sl ings over 60 mm diameter are not intended for general service and are subjected to special conditions
relating to design, construction, frequency of use, service and discard.
b) T he mass of the load is generally calculated or measured with considerable accuracy and as such slings
are usually specially manufactured for one or a limited number of special lifts.
c) T he lifting operation is controlled and supervised.
d) T he dynamic factors, e.g. shock loading, are limited.
These factors reduce the unknown aspects which dictate that slings in general service require a higher coefficient
of utilization; lower coefficients have been and are used with confidence.
1 Scope

steel wire rope grommets, cable-laid grommets and cable-laid slings using strand and wire rope conforming to

4 Hazards
Accidental release of a load, or release of a load due to failure of a sling or a component puts at risk, either directly
or indirectly, the safety or health of those persons within the danger zone.
These aspects of safe use associated with good practice are given in prEN 13414-2.
Table 1 contains all the hazards which require action to reduce risk identified by risk assessment as being specific
and significant for slings and their components.

5.1 Grommets
5.1.1 Production of grommets
During the production of grommets a temporary rigid core shall be used. Grommets and cable-laid ropes shall be
produced using a method which ensures that the rope or strand tensions are equalized and that the finished
product is free from visible waviness.
5.1.2 Construction of wire rope grommet
The strand used to form the wire rope grommet shall be one of those used to form ropes specified in table 2, 4, 6,
8, 11, 12 and 13 of EN 12385-4:2000.
The length of the circumference shall be at least five times the grommet lay length. The core butt position shall be
clearly marked by red paint applied over any serving.
5.1.3 Construction of cable-laid grommet
Cable-laid grommets shall be constructed in accordance with A.1. The unit ropes shall be of 6- or 8-strand
construction selected from those specified in tables 2, 3, 4, 5, 6, 7, 8, 11, 12 and 13 of EN 12385-4:2000. Ropes
over 60 mm diameter shall have steel rope cores.
The length of the circumference shall be at least five times the grommet lay length.
The core butt position shall be clearly marked by red paint applied over any servings.
NOTE The grommet should never be bent at this marked position.

5.1.4 Length of grommet
The length of a grommet shall be the length of its circumference, measured along its centreline (see fig 1).
For wire rope grommets the tolerance shall be 1d or 1% of the nominal length whichever is the greater.
For cable-laid grommets constructed from unit ropes with a fibre core of 24mm d 60mm the tolerance shall be
1d or 1% of the nominal length whichever is the greater.
For cable-laid grommets constructed from unit ropes with a steel core of 24mm d 60mm the tolerance shall be
1d or 1% of the nominal length whichever is the greater.
For cable-laid grommets constructed from unit ropes with a steel core of 66mm d 696mm the tolerance shall be
0,5d or 0,5% of the nominal length whichever is the greater.
NOTE Two methods of determination of the length of grommets, either by measuring the distance of the bearing points or,
more accurately, by measurement of the circumference are described in annex B.
For the measurement process pin sizes shall conform to annex C.

5.2 Cable-laid slings
5.2.1 Construction of cable-laid sling
Cable-laid slings shall be constructed in accordance with A.2.
The unit ropes used shall be of 6- or 8-strand construction selected from those specified in tables, 2, 3, 4, 5, 6, 7, 8,
11, 12 and 13 of EN 12385-4:2000.
Cable-laid ropes over 60 mm diameter shall have steel rope cores.

5.2.2 Length of cable-laid slings
The length, L, of a sling, shall be the internal length between the bearing points of each termination whether they
are soft eyes, thimbles, or hooks or links, as appropriate (see figure 2).
NOTE 1 When measuring the actual length of a sling with soft eyes, dimension w should be approximately ½h (see figure 2)
with h being approximately 15d.
The tolerance of length of ferrule-secured and spliced cable-laid slings shall be ±2d or ±1% of the nominal length,
whichever is the greater. This applies for diameters 24mm
When measuring length under load, for instance when two or more slings are required to be accurately matched for
length, this shall be undertaken at 3 % of the calculated sling breaking force using pins having diameters
conforming to Annex C.
NOTE 2 The dimensions of the eye should be selected so that h is approximately 15d.
5.2.3 Length of matched sets
Where single leg cable-laid slings are intended to be used as matched sets, the difference in length shall not
exceed 2d.
