ISO的钢的Ⅴ型缺口梁式冲击试验,测定所吸收的能量用符号KV表示.在ISO R148规定测定所吸收的能量可不除以试样的堆截面面积;这时,按1kgf·m=9.80665J≈9.807J 来计算;当计算精度要求不高时,亦可取1kgf·m≈10J。ISO的钢的夏比冲击试验(U 形刻槽),测定所吸收的能量用符号KU 表示。本表由冯国光按1kgf·m/cm~2=7.8453J≈7.845J以4舍5入计算(试样截面面积为0.8cm~2)。
ISO Ⅴ notch steel beam impact test, measured by the energy absorbed by the symbol KV. Determination of ISO R148 Determination of energy absorbed by the sample can not be divided by the pile cross-sectional area; at this time, press 1kgf · m = 9.80665 J ≈ 9.807J to calculate; when the calculation accuracy is not high, it can be taken 1kgf · m ≈ 10J. ISO steel Charpy impact test (U-shaped groove), measured by the energy absorbed by the symbol KU said. The table by Feng Guoguang by 1kgf · m / cm ~ 2 = 7.8453J ~ 7.845J to 4 homes 5 into the calculation (sample cross-sectional area of 0.8cm ~ 2).
