Introduction
This document is a Type C standard as stated in EN ISO 12100:2010.

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are

indicated in the scope of this document.

It is understood that type testing of a ferrule-secured eye termination system is the responsibility of the

ferrule-secured eye termination system designer.

It is also understood that the ferrule supplier is responsible for ensuring that the material, design, and

quality of the ferrule is in accordance with the ferrule-secured eye system designer’s specification.

Ferrule-secured eyes manufactured by the ferrule-secured eye termination producer in accordance with this

document are permitted for use as rope terminations in the production of steel wire rope slings. They are

also used as terminations for steel wire rope assemblies for raising, lowering, and supporting loads.

The steel wire rope terminations concerned and the extent to which hazards, hazardous situations and

events are covered are indicated in the scope of this document.

When provisions of this type C standard are different from those which are stated in type A or B standards,

the provisions of this type C standard take precedence over the provisions of the other standards, for steel

wire rope terminations that have been designed and produced according to the provisions of this type C

standard.

4 List of hazards

This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with

in this standard, identified by risk assessment as significant for this type of steel wire rope termination and

which require action to eliminate or reduce the risk.

5 Safety requirements and/or measures
5.1 Ferrule-secured system
5.1.1 General

The ferrule-secured system shall comply with the safety requirements and/or protection measures of this

clause.

In addition, the ferrule-secured systems shall be designed according to the principles of EN ISO 12100 for

relevant hazards but not significant, which are not dealt with in this document.

The ferrule-secured system designer shall carry out type testing in accordance with 5.1.2.

The ferrule-secured termination system designer shall provide instructions on how to produce the ferrule-

secured termination and/or the ferrule-secured endless loop.

The instructions shall at least cover those items given in 5.1.3 and be supported with a written declaration

that the system has passed the type testing requirements of 5.1.2.

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.
---------------------- Page: 10 ----------------------
oSIST prEN 13411-3:2022
prEN 13411-3:2022 (E)
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

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

minimum of 1x10 cycles and not exhibit a complete strand fracture.

5.1.3 Instructions to be provided by the ferrule-secured system designer

The ferrule-secured system designer shall provide instructions on at least the following:

a) preparation of the rope end;
b) details of the rope(s) for which the system is designed;
c) matching of the ferrule material and size to the rope diameter and type;
d) positioning of the rope end;
e) procedure for ferrule-securing, i.e. pressing the ferrule;
f) alignment, condition and maintenance of the tooling;
g) procedure for removal of fins;
h) dimensional requirements of the pressed ferrule;
i) marking limitations of the ferrule; and
j) temperature limits of the ferrule secured system.
5.2 Ferrules
5.2.1 Material

The material selected by the ferrule manufacturer shall be non-alloy carbon steel or aluminium and shall

conform to the same specification as that used by the ferrule-secured system designer when satisfying the

type tests.
Non-alloy carbon steel shall be a fully-killed non-ageing normalized steel.
Aluminium shall be in condition ‘F’ according to EN 515.
5.2.2 Dimensions

The dimensions of the ferrule shall be in accordance with those used by the ferrule-secured system designer

when satisfying the type tests.
5.2.3 Manufacture and quality control of ferrule

The tube from which ferrules are made shall be free from any cracks, folds and surface defects.

With the exception of steel ferrules for Flemish eyes, ferrules shall be produced to provide a seam-free

hollow product. Extrusion over mandrels with a bridge shall not be used. Electric resistance welding of steel

tubes may only take place steel ferrules for Flemish eyes and shall be carried out prior to the tube drawing

and normalizing processes.

For each batch of steel ferrules produced from the same cast of steel and heat treatment a sample ferrule

shall be selected and close flattened at ambient temperature, see Figure 1. If the sample fails this test a

further ten (10) or 3 % of the batch of ferrules, whichever is the greater, shall be randomly selected, and all

shall pass the flattening test otherwise the whole batch shall be rejected.
