What is the Fabric Pneumatic Bursting Strength Tester?

The pneumatic Bursting Tester also named the pneumatic Bursting Strength Tester, is to determine the bursting pressure of fabrics, such as knits, woven fabric, non-woven fabric, laminated fabric, and other craft-made fabric. Besides, compared with the Digital Bursting Strength Tester, the pneumatic bursting strength apparatus enjoys a wider market. TESTEX is one of the Pneumatic Bursting Strength Tester Manufacturers, providing them at reasonable prices.

The pneumatic bursting tester controls the bursting return automatically instead of manual control by the mechanical drive. As a result, this bursting tester can avoid accidental damage to the rubber diaphragm. Besides, automatic data storage, processing, display, and printing, bursting distension measurement by the direct method rather than the traditional expansion method. With these improvements, the instrument test accuracy and its data reliability go to a higher level.

It can also measure the specimen extension prior to bursting. When testing, the instrument applies the pneumatic test method. In addition, the instrument can display the test curve in real time via the software during the test. Moreover, there is no worry about operation safety as the device owns a transparent acrylic cover. And the operation is easy since there are four most commonly applied test areas available.

What is fabric bursting strength?

In the process of use, the fabric is constantly subjected to a concentrated load of bursting, which causes the fabric to expand until it is damaged. For example, the elbows, knees and other parts of the clothing, this damage is called bursting strength.

fabric bursting strength

As the fabric is subjected to bursting during use, the fabric extends longitudinally and shrinks horizontally. If only the tensile breaking strength of the fabric is tested, a single directional break does not actually reflect the wearing situation, so it must be tested in three directions: longitudinal, transverse and oblique. This problem can be solved by using a fabric bursting strength tester.

Fabric Bursting Strength Test Standard

  • ISO 13938-1: Textiles – Bursting strength testing – Hydraulic method for determination of bursting strength and bursting distension
  • ISO 13938-2: Textiles – Bursting strength testing – Pneumatic method for determination of bursting strength and bursting distension
  • GB/T 7742: Textiles – Hydraulic method & Pneumatic method for determination of bursting strength and bursting distension

How to test the bursting strength of fabric?

Test principle

Clamp the test specimen to the expanding diaphragm with a circular clamping ring and apply air pressure to the underside of the diaphragm. As the air pressure increases, the fabric expands until it bursts, thus determining the bursting strength and expansion rate of the specimen.

Test process

  1. Before testing, prepare the fabric bursting strength tester, cut the specimen as required and conditioning it for use.
  2. Select a suitable test area according to requirements. 50 cm² is suitable for most fabrics.
  3. Set the test parameters for the fabric bursting strength tester.
  4. Place the specimen on the diaphragm and clamp the specimen to prevent slippage.
  5. Apply pressure and start the test. At the end of the test, record the relevant data and write a test report.

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 a 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, have featured 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.

    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.
