4.73 (15 reviews)

The HydroBurst Burst Strength Tester utilizes hydraulic bursting (diaphragm method) to determine the burst strength and expansion of knitted fabric, woven fabric, non-woven fabric, laminated fabric, elastic woven fabric, paper, and other materials when subjected to stress in both warp and weft directions, as well as in all other directions, to get the material’s burst strength.

It is also called a BS tester or Mullen Burst Tester. The HydroBurst Burst Strength Tester is widely used for fabric or paper burst tests.TESTEX is a professional Burst Strength Tester manufacturer.

We provide you with hydraulic bursting strength testers but also pneumatic bursting strength testers. Our Digital Bursting Strength Tester complies with many bursting strength test standards, such as GB∕T7742.1-2005, ISO13938-1-2019, ASTM D3786/D3786M-18, etc.




Smart instrument

This Burst Tester can be connected to a mobile phone, allowing remote control and monitoring of the testing status. The burst strength test results can be obtained directly and printed, and equipment warning reminders can be received. Additionally, this BS tester achieves one-click sharing of the testing status.

Smooth operation, precise and durable

The hydraulic system of this Burst Tester adopts full servo control and precise screw drive, providing smooth operation, precise and durable transmission, and low noise. So it is a user-friendly burst strength tester.

High-precision testing

The pressure measurement part of this BS Tester is equipped with a high-precision pressure sensor, with an accuracy of up to 0.2, which means the burst test deviation is 0.2% of the maximum range.

Longer service life of sensors

The Mullen Burst Tester is equipped with Panasonic laser displacement sensors with no rod, so it is easy to replace testing cups, thus providing sensors with better protection and reducing the risk of damage compared to traditional rod-type sensors.

Automatic testing improves efficiency.

During the burst strength test process, the protective cover automatically descends, and the BS tester cup is pressed for testing. When the burst strength test is completed, the testing cup of this Burst Test Machine automatically lifts, and the protective cover automatically ascends. The burst test process is automated, without manual operation, which improves work efficiency and reduces operation risks.

A smart identification system for testing cups

When changing the BS testing cup, the system can automatically identify the current testing cup model and switch the testing parameters automatically, which also greatly improves work efficiency. In addition, the mechanical shell of HydroBurst BS Tester is made of steel plate with an electrostatic spraying process, which makes the appearance generous. The mechanical interior is mainly composed of a high-quality lightweight aluminum structure, which greatly reduces the weight of the whole machine.

Application of Bursting Strength Tester

Bursting Strength Tester is applicable for truck covers, trampoline fabrics, swimming pool covers, compactor curtains, agricultural bagging applications, etc. We should test the above textiles using a burst tester to ensure the burst strength meets the specified requirements.

The HydroBurst Digital Bursting Strength Tester provides a digital pressure value with a peak hold facility and renewable rubber diaphragms. In addition, an automatic clamping device with a clear acrylic bell and an LED lamp is equipped for easy observation. It is easy for users to burst the strength of the fabric and the burst strength of paper.

Test Principle of Bursting Strength Tester

The specimen is fixed on a deformable film and then the film is hydraulically squeezed until the fabric is swollen. The difference between the total pressure required to expand the sample and the pressure required to squeeze the film is fabric expansion strength. Using our fabric bursting strength tester can do a bursting test of fabric.

Significance of the bursting strength test of fabric

Tensile strength testing is less applicable to certain fabrics (e.g. knitted fabrics and lace) when bursting strength testing is possible. When a fabric breaks it is often subjected to pressure in the warp, weft, and diagonal directions. Some knitted fabrics, such as weft knitted fabrics, stretch in a straight line and shrink in a transverse direction, with the straight and transverse directions interacting with each other. In the case of tensile strength testing, it needs to test the warp, weft, and diagonal directions separately, whereas the bursting strength allows for a one-off evaluation of the fabric strength.

Terminology and definitions

Test area: refers to the area of the specimen in the ring gripper.

Bursting pressure or named pressure at burst: the maximum pressure applied to the specimen held together with the lower gasket diaphragm until the specimen bursts.

Bursting strength, also called strength at burst: the pressure obtained by subtracting the diaphragm pressure from the average bursting pressure.

Diaphragm pressure: the pressure applied to a diaphragm to achieve the average bursting expansion of a specimen in the absence of a specimen.

Bursting distension also named distension at burst: the degree of expansion of the specimen under the bursting pressure, shown in the form of the bursting height or bursting volume.

Height at burst:  the distance between the upper surface of the specimen before expansion and the top of the specimen at the bursting pressure.

volume at burst: the required liquid volume when it reaches the bursting pressure.

time to burst: the time when the fabric sample expands to burst out

Test principle

The specimen is clamped on the extendable diaphragm under which liquid pressure is applied so as to expand the diaphragm and the specimen. The volume of liquid will be increased at a constant rate until the specimen ruptures, and the bursting strength and bursting expansion can be measured.

The sampling

The sample should be taken in accordance with the standard of products or the relevant agreement. Folds, creases, fabric edges, or areas that are not representative of the fabric are not allowed to appear on the surface of the sample. The test can be carried out by working the clamping system without the requirement of cutting the sample generally.

Test procedure

Before the test, the sample should undergo conditioning in a relaxed state in accordance with related standards. During the test, keep the specimen in the specified conditioning and the atmosphere needed for the test.

Note 1: The test area should be 50c㎡ for most fabrics, especially knitted fabrics. However, the test area should be at least 100c㎡ for the fabric with low elongation based on the experience and pre-testing, such as the industrial fabrics.

Note 2: The comparative experiment should be carried out at the same increasing rate of the test area and the volume.

Set a constant volume growth rate at between 100 cm3/min and 500 cm㎡3/mimin. Or conduct a pre-test and adjust the bursting time of the test to 20s±5s.

Place the specimen on the diaphragm in a flat and tension-free state to avoid deformation in its plane. Clamp the specimen with the clamping ring to avoid damage and prevent it from slipping during the test. Adjust the dilatancy recording device to zero and tighten the safety cover according to the requirements of the instrument. Apply pressure to the specimen until it is destroyed.

Immediately reset the instrument after the destruction of the specimen, and then record the bursting pressure, bursting height or bursting volume. If the damaged area of the specimen is close to the edge of the clamping ring, the fact should be recorded.

Next repeat the test on different parts of the fabric. At least 5 test samples should be taken. If the buyer and seller make a consensus, the test sample can be increased.

Determination of Diaphragm Pressure

The diaphragm keeps expanding until it reaches the average bursting height or volume under the above-mentioned experimental condition.

Wetting test

In the wetting test, specimens should be impregnated in the water at third level with a temperature of 18 or 22℃. Take the specimen from the liquid and use the absorbent paper to absorb excess water.
