This paper deals with a statistical data pooling method for two different fatigue life data and its application to multiple samples from the data base. The proposed data pooling method is based on the statistical tests of significant difference between regression curves fitted to S-N data. Those treated in this paper are: (a) for inclined parts, (1)test of linearity, (2)test of equality of residual squares and (3) test of equality of regressive coefficients,and (b) for horizontal parts, (4) test of equality of mean and (5) test of equality of variances. As an extension of the method, the algorithm of pooling multiple samples is also developed. The proposed method is applied to the fatigue life data base of metallic materials compiled by the Society of Materials Science,Japan,as an illustrative example.
