6.4.1.2    Method of test

Mount and secure the test piece in the machine so as to ensure that all the wires in the rope are subjected to the force during the test. If sockets or cones are used, the method of socketing shall be in accordance with EN 13411-4.

After 80 % of the minimum breaking force F_min has been applied, the force shall be increased at a rate of not more than 0,5 % of the minimum breaking force per second.

NOTE Cyclic loading can be applied up to 40 % of the minimum breaking force of the rope. This should be recorded in the technical file.

The measured breaking force value F_m is reached when no further increase in applied force is possible and the rope is broken.

The test may be terminated without breaking the rope when the minimum breaking force value is achieved or exceeded.

The test may be discounted where the rope fracture occurs within a distance of six rope diameters from the base of the grip or the termination and the minimum breaking force has not been achieved.

6.4.2    Method 2 - Measured aggregate breaking force F_em

Unless specified otherwise in the appropriate part of this standard, the measured aggregate breaking force F_{e m} shall be determined by adding together the breaking forces of all the individual wires from the rope after they have been tested in accordance with the wire tensile test specified in EN 10264-1.

6.4.3    Method 3 - Calculated measured (post-spin) breaking force Fm._c

aggregate breaking force F_em in accordance with Method 2, and multiply this value by either a) the spinning loss factor k, as given in the other parts of this standard or b) the partial spinning loss factor obtained from the results of type testing.

When the calculated measured (post spin) breaking force F_{m c} fails to meet the minimum breaking force value F_min another test, using Method 1, shall be carried out.

In the case of failure to meet the intended minimum breaking force value when tested in accordance with method 1, type testing in accordance with annex A shall be repeated.

-    over 12 mm up to and including 24 mm;

-    over 24 mm up to and including 48 mm;

-    over 48 mm up to and including 60 mm.

For each of the sub groups representing the intended size range and having the same construction, grade and minimum breaking force factor, the manufacturer shall perform a breaking force test in accordance with 6.4.1 on a sample from each of three separate production lengths of rope of different nominal diameters.

If all three samples pass the test, all rope sizes within that sub group of that particular rope construction, grade and minimum breaking force factor shall be deemed to have satisfied the type testing requirements; otherwise, breaking force testing shall continue on a sample from each consecutive production length of rope within that sub-group until the above requirements are met.

A.1.2 Ropes having different minimum breaking force factors throughout a sub-group of rope diameters

The manufacturer shall perform a breaking force test in accordance with 6.4.1 on a sample from each of three separate production lengths of rope of the same nominal diameter.

If all three samples pass the test, that rope diameter and constmction having that particular minimum breaking force factor shall be deemed to have satisfied the breaking force type testing requirements.

If one of the samples fails the test, the tests shall be repeated until the measured breaking forces F_m of three consecutive production lengths of that rope diameter and construction meet or exceed the minimum breaking force value F_min.

For each rope of a given diameter, construction and minimum breaking force or minimum aggregate breaking force, the manufacturer shall perform a breaking force test in accordance with 6.4.1 or 6.4.2 respectively, on a sample from each of three separate production lengths.

If all samples pass the test, that rope diameter and construction having that particular minimum breaking force or minimum aggregate breaking force shall be deemed to have satisfied the breaking force type testing requirements.

If one sample fails the test, the tests shall be repeated until the measured breaking forces or measured aggregate breaking forces of three consecutive production lengths of that rope diameter and construction meet or exceed the minimum breaking force or minimum aggregate breaking force value respectively.

Alternatively, where the manufacturer intends to produce multiple production lengths of the same rope on the same closing machine with the same machine settings to the same rope design, sampling and breaking force testing may be in accordance with the following:

■Jn- 1 rounded down to the next whole number with a minimum of 1

where N - number of production lengths (i.e. closer loadings)

The ropes shall be deemed to comply if the measured breaking force(s), or measured aggregate breaking force(s), when tested in accordance with 6.4.1 or 6.4.2 respectively, meet or exceed the minimum value.

If one of the samples fails the test, tests shall be carried out on a sample from each of the remaining production lengths.

Only those ropes that pass the test shall be deemed to have satisfied the breaking force requirement.

5.3.2    Tolerances

When measured in accordance with 6.3 the measured diameter or the measured width and thickness shall not vary from the nominal by more than the tolerance(s) specified in the appropriate part of this standard.

5.4    Breaking force

5.4.1 General

The minimum breaking force F_min or, where specified in the other parts of this standard, the minimum aggregate breaking force F_{e min} for a given size, grade (where applicable) and construction or class of rope shall be either,

a)    in accordance with the value or calculation given in the appropriate part of this standard; or

b)    as stated by the manufacturer.

When tested in accordance with Method 1 as described in 6.4.1 the measured breaking force F_m shall be equal to or greater than the minimum breaking force F_min.

When tested in accordance with Method 2 as described in 6.4.2 the measured aggregate breaking force F_{e m} shall be equal to or greater than the minimum aggregate breaking force F_{e min}

When tested in accordance with Method 3 as described in 6.4.3 the calculated measured (post-spin) breaking force F_{m c} shall be equal to or greater than the minimum breaking force F_min.

Unless specified otherwise in the appropriate part of this standard, breaking force testing shall be in accordance with Table 1.

NOTE The requirements for breaking force testing take into account (i) the rope size, (ii) whether or not ropes are produced in series i.e. repeatedly produced, (iii) whether or not the minimum breaking force factor is consistent throughout a sub-group of rope diameters and (iv) whether or not the manufacturer is operating a quality system in accordance with EN ISO 9001 certified by an accredited third party certification body, see 5.4.2.
