Bursting strength is an important index of textiles mechanical properties. Some relations c the test parameters were found on the study of GB/T 7742. 1 -2005. Test area and bursting strength hav an inverse relation. For the same sample, the breaking strength of old standard recommended area 7. 3 cm is about 3 times of that of the existing standards recommended area 50 cm 2 . Bursting speed has little effec on the bursting strength. Bursting strength would increase slightly when bursting speed increase. There is certain linear relationship between bursting speed and bursting time in small adjustments arrangement. S bursting speed could be adjusted quickly to the standard bursting time. This test method has goo precision,and the coefficient of variation ( CV) of uniform sample test results is less than 1% . Source
