Test Principle of Bursting Strength Tester
Our Fabric Bursting Strength Tester operates by securely fixing the fabric specimen onto a deformable film. The Digital Bursting Strength Tester then applies hydraulic pressure to the film, causing the fabric to expand until it bursts. The Bursting Strength Apparatus calculates the fabric’s expansion strength by measuring the difference between the total pressure required to burst the sample and the pressure needed solely to deform the film. This reliable and precise method ensures accurate assessment of fabric durability and expansion strength, making our tester ideal for professional textile testing applications.
Significance of the bursting strength test of fabric
Tensile strength testing is not as relevant for certain fabrics, such as knitted materials and lace, where bursting strength testing can be more appropriate. When a fabric fails, it typically experiences pressure in the warp, weft, and diagonal directions. For instance, some knitted fabrics, like weft knitted types, stretch in a linear direction while contracting transversely, with these two directions influencing one another. In tensile strength testing, it is necessary to evaluate the warp, weft, and diagonal directions individually, whereas bursting strength testing provides a comprehensive assessment of the fabric’s overall strength in a single evaluation.

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.

A: Test Principles:
Tensile Strength Test: The specimen is clamped in a circular fixture on a fixed base. A spherical plunger moves vertically at a constant speed, pushing the specimen until it ruptures. The force required to break the specimen is measured as the ball burst strength.
Bursting Strength Test: The specimen is clamped onto a stretchable diaphragm, and liquid pressure is applied beneath the diaphragm, causing both the diaphragm and the specimen to expand. The volume of liquid is increased at a constant rate until the specimen ruptures, allowing the measurement of bursting strength and bursting expansion.
Test Instruments:

Pneumatic Burst Testing Machine: Simpler and generally lower in cost.
Q: What factors affect the results of fabric burs strength tests?
A: Fabric thickness, fiber composition, weaving process, moisture content, and test conditions—such as temperature and humidity—each play a significant role in influencing the results.
Q: What issues can arise from using non-standard sample specifications? What are the sampling requirements for different standards?
A: Yes, using non-standard sample specifications can lead to issues. If the sample dimensions, thickness, or cutting do not meet the standard requirements, the test results may be inconsistent. It is essential to ensure that the sample specifications comply with the standards.
GB/T 7742.1—2005: Sample diameter of 30-50 mm, with at least 5 samples.
ASTM D3786/D3786M:2013: Sample diameter of 30-40 mm, with 5-10 samples.
ISO 13938-1:2019: Sample diameter of 50 mm, with at least 5 samples.
Q: Does aging or damage of the test membrane affect the test results?
A: Yes, aging or damaged test membranes cannot distribute pressure evenly, which may lead to inaccurate burst strength test results. The test membrane should be replaced regularly.
Q: Is it necessary to use a Mullen Bursting Tester to measure Mullen Bursting Strength?
A: Yes, using a Mullen Bursting Tester is essential for accurately measuring Mullen Bursting Strength. This tester is specifically designed to apply controlled hydraulic pressure to a material until it bursts, yielding precise data on the force needed for rupture. Without a Mullen Bursting Tester, consistently and reliably measuring the bursting strength of materials would be challenging, making it a crucial tool in industries such as textiles, paper, and packaging.
Q: What factors affect the burst strength of paper?
A: The burst strength of paper is influenced by factors such as fiber composition, density, moisture content, thickness, calendering, additives, and the manufacturing process. Stronger fibers, higher density, and optimal moisture levels increase burst strength, while thicker paper, calendering, and coatings further enhance durability. Variations in production can also impact the overall strength.
