EN 13411-3:2022 (E)
In the particular case of oval ferrules with tapered ends used in the securing of the turn-back eye or
endless loop where the rope end is contained within the ferrule, the ferrule-secured system designer shall
provide means whereby the position of the rope end before and after pressing can be ascertained. This
shall not include verification by marking the rope. Only the parallel portion of a ferrule shall be
considered load bearing.
5.1.2 Type testing
5.1.2.1 Sampling
Where the ferrule design follows a mathematical progression throughout a given size range, rope
diameter shall be selected for testing to represent the lower and upper quartiles of that range.
Where the ferrule design does not follow a mathematical progression throughout a given size range, each
rope diameter within that range for which the system is designed shall be selected for testing.
For each rope diameter selected as above, the rope grade shall be the highest for which the system is
designed and at least three FSETs or three ferrule secured endless loops, whichever is the case, shall be
tested.
NOTE 1 In the case of the FSET, the number of tests is regarded as two when the test lengths have a FSET at both
ends.
Additionally, sampling shall take into account whether the type of ferrule-secured termination is a turn-
back eye or Flemish eye or whether it is an endless loop, as follows:
a) Turn-back eye ferrule secured-termination
Testing shall be carried out on each of the basic rope types for which the system is designed. For each
basic rope type, testing shall be carried out on ropes having the lowest and highest metallic cross-
sectional area factors for which the system is designed.
NOTE 2 For the purposes of this document there are four basic rope types, namely single layer rope,
rotation-resistant rope, parallel-closed rope, and spiral strand rope, refer to EN 12385-2 for definitions.
b) Flemish-eye ferrule-secured termination
Testing shall be carried out on single layer rope having the lowest and highest metallic cross-
sectional area factors for which the system is designed.
c) Ferule-secured endless loop
Testing shall be carried out on single layer rope having the lowest and highest metallic cross-
sectional factor for which the system is designed.
5.1.2.2 Tensile test
When tested in accordance with 6.2, the FSET shall sustain a force of at least 90 % of the minimum
breaking force of the rope.
NOTE A terminal efficiency of 90 % is equivalent to a termination efficiency factor, K , of 0,9 which is used in
T
the calculation of WLL for slings.
When tested in accordance with 6.2, the ferrule-secured endless loop shall sustain a force of at least 90 %
of twice the minimum breaking force of the rope.

5.1.2 Type testing
5.1.2.1 Sampling
Where the ferrule design follows a mathematical progression throughout a given size range, rope diameter
shall be selected for testing to represent the lower and upper quartiles of that range.
Where the ferrule design does not follow a mathematical progression throughout a given size range, each
rope diameter within that range for which the system is designed shall be selected for testing.
For each rope diameter selected as above, the rope grade shall be the highest for which the system is
designed and at least three FSETs or three ferrule secured endless loops, whichever is the case, shall be
tested.
NOTE 1 In the case of the FSET the number of tests is regarded as two when the test lengths have a FSET at both
ends.
Additionally, sampling shall take into account whether the type of ferrule-secured termination is a turn-back
eye or Flemish eye or whether it is an endless loop, as follows:
a) Turn-back eye ferrule secured-termination
Testing shall be carried out on each of the basic rope types for which the system is designed. For each
basic rope type, testing shall be carried out on ropes having the lowest and highest metallic cross-
sectional area factors for which the system is designed.
NOTE 2 For the purposes of this standard there are four basic rope types, namely single layer rope, rotation-
resistant rope, parallel-closed rope, and spiral strand rope, refer EN 12385-2 for definitions.
b) Flemish-eye ferrule-secured termination
Testing shall be carried out on single layer rope having the lowest and highest metallic cross-sectional
area factors for which the system is designed.
c) Ferule-secured endless loop
Testing shall be carried out on single layer rope having the lowest and highest metallic cross-sectional
factor for which the system is designed.
5.1.2.2 Tensile test
When tested in accordance with 6.2 the FSET shall sustain a force of at least 90 % of the minimum breaking
force of the rope.
NOTE A terminal efficiency of 90 % is equivalent to a termination efficiency factor, K , of 0,9 which is used in the
T
calculation of WLL for slings
When tested in accordance with 6.2 the ferrule-secured endless loop shall sustain a force of at least 90 % of
twice the minimum breaking force of the rope.
5.1.2.3 Fatigue test
When tested in accordance with 6.3 for 75 000 cycles followed by a tensile test in accordance with 6.2 the
FSET and endless loop shall sustain a force of at least 80 % of the minimum breaking force of the rope.
Additionally for Flemish eye ferrule-secured terminations of crane hoist ropes a further fatigue test shall be
performed on an assembly comprising a solid thimble having a peripheral length equivalent to at least four
rope lay lengths. When tested in accordance with 6.4 the ferrule-secured termination shall withstand a
6
minimum of 1x10 cycles and not exhibit a complete strand fracture.
