    A method of deciding whether an article filled with a feather and down mixture is properly labeled was published in 1971. It required the calculation of three factors: the mean, the standard deviation, and the t statistic. The present paper presents tables of acceptance values for various combinations of producer risk and consumer risk, eliminating the need for the calculation of the t statistic. The previous paper required a minimum sample of four specimens, while the present paper provides an opportunity for reduced sampling and testing by presenting acceptance values for n = 2 and n = 3, which can be used in routine quality control work. Finally, operating characteristic curves, showing how the probability of acceptance varies with the percentage of down in the finished product, are given for several different plans.
