Auto Bursting Strength Tester Test Method
What is bursting strength tester:
The definition of bursting machine is a kind of textile testing instrument to determine the bursting strength of paper, fabric, knitted fabric, and so on, this is also the reason why it has appeared. In order to provide customers with simple and understandable operation method, bursting strength tester manual is enclosed.
(For more information in detail, please see bursting strength tester Wikipedia)
Bursting strength test principle:
The bursting strength can be measured when the specific test piece is pressed by hydrostatic pressure continuously until the test piece has sudden burst.
Bursting strength test procedure:
- Turn on the power.
- Turn on the air pump and adjust the air pressure governor to ensure that air pressure in a reasonable range.
- Taking down the glass cover and loosening the diaphragm pressure plate, we should put the diaphragm into the plate and tighten it up, after that, putting the glass cover. (Attention: Don’t fold the diaphragm.)
- According to the standard to prepare the specific test piece and put the test piece on the plate, we click the “down” button on the touchscreen.
- We settle the parameter on the bursting strength testing machine.
- Choose a way to burst, we set both “P” and “EXP” to be zero. We need to click the “start” button and wait for the finish of the test. (Attention: If the material of test piece is different to the last one, it needs to be carried out a preliminary experiment less than 3 times.)
- When the burst testing time of test piece up to standard, we need to start the no-load test of the diaphragm and record its pressure automatically until it is stopped by itself.
- The data is displayed on the screen, but the calculated result is only shown in the printing report.
Bursting strength formula:
Bursting strength: (kN/m2)= A-B
(Attention: 1Mpa=1000kN/m2; Bursting strength unit: kN/m2)
In the equation:
A – The average of burst strength, kN/m2
B – The number of diaphragm calibration, kN/m2
Bursting strength tester calibration:
- Doing the first test with the sample, and doing another test with calibration plate, we should set the same parameters in order to compare both results of them.
- In analyzing two results, if they are the same, the bursting machine needn’t calibrate. On the contrary, it needs a calibration.
- If the first test result displays 70kPa, but the second one displays 60kPa, there is 10kPa difference between two test results.
- Adjusting the 10kPa calibration pressure, and then touch “enter” button, it will display the pressure as 70kPa, and the calibration is finished.

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: What is bursting strength units?
A: The unit of bursting strength is “kN/m^2”.
Q:What’s the bursting strength formula and how to 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.
