This trial measures the number of molten metal drops needed to increase the temperature of the calorimeter behind the sample, 40°K.

The trial will be performed on 10 samples measuring 120 mm x 20 mm.

The composition of the test rods is very important, as it affects the ability to reproduce the results. The composition must abide by standard ISO 636, and linear density must be (0.5 + 0.2) g/cm.

One end of a steel rod is smelted on the flame of an oxyacetylene blowtorch with a diameter of 1.2 mm. The rod will be pushed forward with a variable-speed motor and a pulley system. Prior to performing the test, the speed of the motor must be adjusted so that the steel rod can be fed into it at a speed of 10 g/min. Once all parameters have been adjusted, the test consisting of projecting molten metal drops on the same area of the sample will be performed.


该试验测量了将样品后面的量热计温度升高40°K所需的熔融金属滴数。
试验将在10个尺寸为120 mm x 20 mm的样品上进行。
测试棒的成分非常重要,因为它会影响再现结果的能力。成分必须符合ISO 636标准,线密度必须为(0.5+0.2)g/cm。
钢条的一端在直径为1.2 mm的氧乙炔喷灯的火焰上熔炼。连杆将通过变速电机和皮带轮系统向前推动。在进行试验之前,必须调整电机的速度,以便以10 g/min的速度将钢条送入电机。调整完所有参数后,将进行试验,包括在样品的同一区域投射熔融金属滴。
