Abstract

This Japanese Industrial Standard 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 107 up to and including 109 , for the base material and junction of structural aluminium alloys and structural magnesium alloys used for rolling stock, marine vessels, automobiles, etc. The high -speed test method specified in this Standard is applicable to the tests in which the number of cycles is 107 or under.
