3 Terms and definitions
There are no terms or definitions that require definition in this document:
4 Test method 6: Elongation
4:1 Elongation at break
Elongation is the ratio of the increase in length to the original length, expressed as a percentage:
On an extensometer or tensile testing machine, extend a calibrated wire with a free test length of:200 mm to 250 mm at a rate of (5 ± 1) mm/s:
The straight specimen is stretched to the conductor breaking point, and the ratio of the linear length increment at the time of breaking to the free test length is calculated and expressed as a percentage:
Test three specimens, record three test values, and take the average value as the elongation at break:
4:2 Tensile strength
Tensile strength is the ratio of the breaking force of a conductor to its original cross-sectional area:
On a tensile testing machine, pull a straightened specimen with a free test length of:200 mm to 250 mm at a rate of (5 ± 1) mm/s:
Extend it to the breaking point of the conductor and record the breaking force:
Test three specimens, record the original cross-sectional area and three breaking force test values, and take the average value of the ratio of breaking force to original cross-sectional area as the resistance value:
