Abstract
When all experimental errors of testing are adequately minimized, cellulose ester sheets show a dispersion of tensile strength values higher than that found for metal strips and wires. The dispersion of “yield point” values is much less than that of tensile strength. It is suggested that the lowest value (or, at any rate, the bracket of values lower than the average) of tensile strength for a number of tests equivalent to a given film length is a better measure of the probability of failure in performance than the average value. However, for comparative rating, it appears that generally the ratio of lowest to average is fairly constant.
