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. 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. SIST EN 13411-3:2004+A1:2008

EN 13411-3:2004+A1:2008 (E) 9 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.
