                     *伸长率的最小值是对250mm标距而言,如果采用其他标距,则这些数值应实用650/(标距+400) 这个系数进行校正。

                        Minimun elongation is based on gauge length l0 = 250mm.

                        **扭转试验试样长度:钢丝直径的100倍。

                        Torsion test is based on a standard length of 100 wire diameters.
