Testing method

Two connection plates, as shown in Figure 11 to Figure 14, are securely attached to a standard tensile

For the tensile test, the sample shall be placed as shown in Figure 11, 12, 13, and 14.

The four lateral hooks on the side of the clamp (two at the bottom and two at the top) will restrain the sample lateral and facilitate elongation measurement during testing.

The strain rate during the test shall be 6mm/min.

A preload of approximately 4000 N will then be applied to adjust the specimen so that each wire will be properly and slightly tensioned.

The test ends when the first wire breaks.

The elongation is calculated by measuring the vertical displacement at the beginning and at the end of the test (left and right readings). The average value of the difference between initial and final displacement (normally obtained when the first wire breaks) will provide the elongation at rupture.

The test will be considered satisfactory when ruptures in a serious of samples will be at different locations and not always close to the hooks. In the latter case, the test could be considered non-satisfactory.

Samples should be manually selvedged on both cross ends to the weave length, in order to guarantee a uniform and full locking effect on the double twists that will be directly solicited.

An example of a manual selvedge consists of manually inserting an additional rob by twisting and bending the wire mesh around it.

The number of samples shall be agreed between supplier and purchaser at the time of enquiry and order. The test report is required after ending the test.
