The object of this study is to measure tension of the netting cord by impact test using strain gauge. The netting cords composed of short fibers and of endless filaments were used. The results obtained were as follows: 1) The breaking strength of the netting cord obtained by impact test is constant independent with the impact force. Regarding to the short fibers cord, breaking strength obtained by impact test are larger than those obtained by static test, respectively. For the endless filaments cord, it is whether same tendency or the formers are smaller than the latters. 2) The breaking elongation obtained by impact test are smaller than those obtained by static test. 3) The breaking energy of the short fibers cord obtained by impact test are larger than those obtained by static test. For the endless filaments cord, it is whether same tendency or the formers are smaller than the latters.
