Elongation Test for 2UEW PT-10 Class 180 AWG 12 Enameled round aluminum wire
LP Industry does elongation test
2UEW PT-10 Class 180 Enameled round aluminum wire
the elongation is qualified about 24% -28% by IEC 60815.
Dimension: AWG12
Elongation is the ratio of the increase in length to the original length, expressed as a percentage. On an extensometer or tensile testing machine, stretch a straightened sample with a free test length of 200mm-250mm to the breaking point of the conductor at a rate of (5+1) mm/s, and calculate the linear increase in length at break and The ratio of the free test length is expressed as a percentage. Three samples are measured, the three test values are recorded, and the average value is taken as the elongation at break.
Enameled wire elongation inspection work instructions
1. Equipment used: elongation testing machine, diagonal pliers
2. Sample preparation: Take a sample with a length of about 400mm, and the wire must not be bent or knotted
3. Test conditions:
3.1 Test environment temperature: general conditions, use temperature: 23±12℃
3.2 Test environment humidity: use humidity 50 ± 20% under general conditions
3.3 Calculation method: automatic calculation of elongation testing machine
4. Test method:
4.1 Manually straighten the sample appropriately, and then clamp it into the tensile tester
4.2 Adjust the tensile range of the tensile tester to be large enough to avoid the narrow range leading to halfway through the test
stop
4.3 Operate strictly in accordance with the operating steps of the tensile test machine
4.4 Record the corresponding results
4.5 When testing the elongation of the enameled wire, pay attention to whether the paint film is cracked, and check its elongation at the same time
5. Elongation:
The elongation at break should not be less than the value specified in the table
