Summary:A method of and apparatus for the determination of the standard tensile yield point in which the extension of a test body is monitored, comprises determining in the course of continuous extension within the elastic limit, the ratio of the instantaneous extension and the associated load, storing this ratio and in the course of further continuous extension the ratios of a given residual extension as well as that of the instantaneous extension and the instantaneous load are determined, the stored ratio value is summed with the ratio of the given residual extension and the instantaneous load, and the thus obtained sum is compared with the ratio of the instantaneous load whereby the instantaneous load at which the compared values become substantially equal gives the tensile yield stress at the given residual.
