Note: 

*d= nominal diameter of specimen

 

*Test bends 180 unless noted otherwise

Bend Test is performed as per ASTM Standards. The test is conducted for each lot of production frequently to confirm the bend-ability. The test is conducted by the 1000KN UTM from Hungta Instrument Co. Ltd.,Taiwan.
