→Used in tensile test for steel wire mesh for elongation measurement.
→Comply with BS EN 10223-3:2013 Steel wire and wire products for fencing and netting Part 3: Hexagonal steel wire mesh products for civil engineering purposes.
→The strain rate during the test shall be 6mm/min.
→A preload of approximately 4000N will 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 displacements 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.
