Bursting and Grab Tests for Knit Fabrics Compared

Abstract

Publication of important textile research work previously unpublished is one of the functions of this magazine. The accompanying paper was presented by the author before Committee D-13 of the American Society for Testing Materials, February, 1925, but only excerpts therefrom have been published heretofore.

In 1925 Committee D-13 of the A. S. T. M. adopted tentatively the 1 × 1 × 1" Grab Test,² and at that time the Burcau of Standards recommended, ³ and the Associated Knit Underwear Manufacturers of America generally adopted this test method. In 1928, however, the A. S. T. M. revised the tentative specifications in favor of a bursting test. ⁵
