This test method describes the measurement of the resistance of textile fabrics to bursting using the hydraulic diaphragm bursting tester .This test method is generally applicable to a wide variety of textile products . Principle； S ample is clamped over an expandable diaphragm. T he diaphragm is expanded by fluid pressure to the point of specimen rupture. The difference between the total pressure required to rupture the specimen and the pressure required to inflate the diaphragm is reported as the bursting strength . Significance and use: This method for the determination of diaphragm bursting strength of knitted, non-woven and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses. In cases where test results obtained using the procedures in Test Method D3786 have not been correl...
