JIS Z 3147:2017规定了在室温下，以超过5000次循环/分钟的频率进行高速旋转杆弯曲疲劳试验（以下简称高速试验），以获得高循环范围内的疲劳寿命，其中循环次数超过10（7）次，达到并包括10（9）次，用于机车车辆、船舶、汽车等结构铝合金和结构镁合金的基材和接头。

JIS Z 3147:2017 specifies the method of high-speed rotating bar bending fatigue testing at room temperature and at a frequency of over 5 000 cycles/min up to and including 8 000 cycles/min (hereafter referred to as high-speed test) for obtaining the fatigue life in the high cycle range, in which the number of cycles is over 10(7) up to and including 10(9), for the base material and junction of structural aluminium alloys and structural magnesium alloys used for rolling stock, marine vessels, automobiles, etc.
