The wires shall be tested in accordance with the wire tensile test specified in ISO 6892. When this method (i.e., Method 2) is used for the periodic test (see Table 6.1) and the calculated measured (post-spin) breaking force value is less than the intended minimum breaking force value, another lest using Method I shall he carried out.
NOTh: The resuli from this test is known as the cakulaied measured Iposi-spini breaking force’.
If the measured (actual) breaking force in this second test fails to meet the intended minimum breaking force value, the minimum breaking force shall be dc-rated to a value not exceeding the measured (actual) breaking force value and type testing shall be repeated using Method I.
In such cases, the rope grade shall either be dc-rated in line with the dc-rated minimum breaking force value or deleted from the rope designation.
7.4.3 Method 3—Calculated measured (pre-spin) breaking force
Add together the measured breaking forces of all the individual wires before they are laid into the rope and multiply this value by the total spinning loss factor obtained from the results of type testing. The total spinning loss factor used in the calculation shall be the lowest value of the three values obtained from type testing.
The wires shall be tested in accordance with the wire tensile lest specified in ISO 6892.
NOTF: The resull from this test is known as the ‘calculated measured (prc-spinh breaking forcc’.
When this method (i.e., Method 3) is used for the periodic test (see Table 6.1) and the calculated measured (pre-spin) breaking force value is less than the intended minimum breaking three value, another test using Method I shall be carried out.
It the measured breaking force in this second test fails to meet the iiitended minimum breaking force value, the minimum breaking force shall be dc-rated to a value not exceeding the measured breaking force value and type testing shall be repeated using Method I.
In such cases, the rope grade shall either he dc-rated in line with the dc-rated minimum breaking force value or deleted from the rope designation.
7.4.4 Breaking force based on component tests
For six-strand rope (round or triangular strand) and eight-strand rope having a breaking force in excess of 1500 kN, the following method of test is allowed as an additional alternative to the methods of testing referred to above. Each of the component strands and. if applicable, the wire rope core from a sample of the completed rope is tested aiid the rope breaking force is calculated from the component strand and core tests as follows:
