Pneumatic Bursting Tester, to determine the bursting pressure of fabrics using pneumatic test method, including knits, woven fabric, non-woven fabric, laminated fabric and other craft-made fabric.
A test specimen is clamped over an expansive diaphragm by a circular clamping ring; increasing compressed air pressure is applied to the underside of the diaphragm, causing distension of the fabric until the test specimen bursts; the bursting strength and distension are determined.
Real time testing-curve is shown on the Bursting software. The machine can also be controlled easily by the graphics touch-screen without computer.

Why Do We Need to Test the Bursting Strength of the Fabric?
When the fabric is worn, it is often subjected to the concentrated load acting perpendicular on the fabric plane (such as knees, elbows, uppers, gloves, socks, etc.), and it bulges and expands until it is damaged, for example, parachute and filter bag have similar force and damage. This phenomenon is called top break or burst. The ability of the fabric to resist bursting is called resistance to burst strength.
Some knitted fabrics, such as weft-knitted fabrics, which have featured by longitudinal extension and transverse shrinkage and they have a strong effect on each other. If a tensile test is applied to measuring fabric strength, the test must be made in radical, weft and diagonal directions. The test of bursting strength is a comprehensive evaluation of fabric strength, only one test, which can provide information on multiple stretch features of the fabrics.
What is the Fabric Pneumatic Bursting Tester?
The bursting strength tester is suitable for measuring the bursting strength and blasting expansion of textiles. It is used for testing the bursting strength of all kinds of materials with impervious properties such as knitted fabric, non-woven fabric, leather, geosynthetics and so on.
The pneumatic bursting tester uses the computer to automatically control over the bursting return instead of manual control by the mechanical drive to avoid accidental damage to the rubber diaphragm. Automatic data storage, processing, display, and printing, bursting distension measurement by the direct method instead of by the traditional expansion method. By these improvements, the instrument test accuracy and its data reliability are raised.
1 Connect the instrument to mains. Press the power switch and show the interface of the instrument.
2 Open the pump, adjust the pressure regulating valve, so that the pressure on the pressure gauge to a reasonable scope. The pressure adjustment is to ensure that the polymethyl methacrylate cover presses against the sample so that the pressure is sufficient and the fabrics wouldn’t move during the testing process.
3 Remove the polymethyl methacrylate cover first, and then insert the rubber ring into the hole, Next put it on the steel rim of the vent hole.
Note: Steel rim shall vary according to the different sizes of the vent hole, which you shall check before installation. At the same time it needs to be screwed airtight, otherwise, gas leakage may occur and it will be unable to carry out a test.
4 Place the membrane neatly on the lower platen, and at last install the glass cover. Please note that do not fold the membrane during the operating process.
5 Install the specimen according to the relevant standards. Click on the DESCEND key on the touch screen until the polymethyl methacrylate cover descends automatically and presses against the specimens, and meantime the lower contact of the displacement sensor in polymethyl methacrylate cover shall be on the upper surface of the specimen. The test completed and the instrument will be automatically stored display test data.
As a professional supplier of textile instruments, we are committed to continually improve the user experience, TESTEX Textile Testing Equipment is a reliable choice for testing textile quality.
Q: What is the definition of bursting strength?
A: You can know it from wikipedia of bursting strength.
Q: What is bursting strength tester principle?
A: 1. In this test the fabric sample is clamped over a rubber diaphragm by means of an annular clamping ring.
2. An increasing fluid pressure is applied to the underside of the diaphragm until the specimen bursts.
3. The operating fluid may be a liquid or a gas.
Q: What is bursting strength test procedure?
A: 1.The fabric sample is clamped over the rubber diaphragm.
2.The pressure in the fluid increases at such a rate that the specimen bursts within 20 ± 3 sec. (P1).
3.The height (extension) of the diaphragm is noted
4.Another test is carried out without a specimen.
5.The pressure to do this is noted and then deducted from the earlier reading.
6.(P1 – P2) is the actual bursting strength of the specimen.
Q: How do you calculate the bursting strength?
A: Bursting strength formula:
Bursting Strength (Kg / cm2) = Bursting Factor x GSM (gm / m2) / 1000
The bursting factor is proportionality constant and has the same value. To determine the bursting strength of a sample, a testing machine named bursting strength tester can be used. Once you get the bursting strength, the bursting factor can be derived from that.
