A STUDY OF THE EFFECTS OF CHEMICALS ON THE PROPERTIES OF PARACHUTE FABRICS (SUPPLEMENT I)

Abstract

The results given in the Technical Report WADC TR 55-340 were obtained by determining the percent loss in strength of nylon and Dacron parachute fabrics when the fabric was treated with chemicals under various conditions. Because fabrics are not absolutely uniform and experimental procedures are not perfectly reproducible. the results of breaking strength tests varied. Since each sample consisted of several breaking tests (usually 10), it was possible to estimate the within sample reliability by statistical means. This was done by calculating the 95% confidence limits.
