The Burst burst strength tester uses hydraulic blasting (diaphragm method) to determine the bursting strength and expansion of knitted fabrics, woven fabrics, non-woven fabrics, laminated fabrics, elastic woven fabrics, paper and other materials under warp stress

Product Detail

Application

Used for measuring the performance of burst strength and burst expansion of various knitted fabrics, woven fabrics, non-woven fabrics, paper, leather, plastics, and other materials when subjected to simultaneous forces in warp and weft directions.

Existing data indicates that there is no significant difference in the bursting strength results obtained using hydraulic and pneumatic bursting instruments when the pressure does not exceed 800kPa. This pressure includes the performance level of most ordinary clothing. For special textiles that require high bursting pressure, hydraulic method is more suitable

Features

1. Adopting industrial grade color touch screen display and control, the user-friendly human-machine interface is simple and easy to understand, and the operation is more convenient. Chinese and English display can be converted.

2. The expansion height adopts non-contact laser ranging technology, which has high measurement accuracy, stability, and reliability.

3. It has four testing methods: constant rate expansion, constant pressure cycling, constant expansion degree, and timed expansion. Multiple testing methods meet the requirements of different industries.

4. The units of bursting strength can be selected (kPa, bar, psi), and the units of bursting height can be selected (mm, cm, inch) to meet the requirements of different standards.

5. Equipped with various sample holders and automatic recognition function of sample fixtures.

6. The sample is clamped using a pneumatic gripper, and the slow pressing method ensures that the sample is not damaged and does not slip.

7. It has a pressure over range protection function to prevent damage to the instrument.

8. The high transparency organic glass sample holder cover is equipped with an embedded LED lighting, which can clearly observe the test process.

9. An external organic glass safety cover is installed to prevent pinching and ensure safer use.

10. It has the function of storing experimental data and printing test reports

Principle of Burst Strength Testing

The burst strength tester evaluates a fabric’s resistance to rupture under pressure. In this method, the fabric sample is clamped securely over a deformable diaphragm. The testing device—typically a hydraulic burst strength tester—then applies fluid pressure beneath the diaphragm. As pressure increases, the fabric expands until it ultimately ruptures.

The burst strength is calculated by subtracting the pressure required to deform the diaphragm alone from the total pressure required to burst the fabric sample. This provides a highly accurate measure of the fabric’s structural integrity and overall strength.

This method is particularly well-suited for testing materials where force may be applied in multiple directions simultaneously, making it a preferred technique in professional textile laboratories.

Why Burst Strength Testing Matters

For certain textiles such as knit fabrics, lace, and nonwovens, traditional tensile strength testing (which measures strength along specific axes—warp, weft, or bias) may not accurately reflect real-world performance. These materials often undergo multi-directional stress during use, especially in garments, upholstery, or industrial applications.

For example, weft-knitted fabrics stretch lengthwise and contract widthwise, creating complex interactions. A burst strength test, by applying uniform pressure in all directions, gives a comprehensive assessment of a fabric’s resistance to rupture. This makes it an indispensable tool in quality control, research and development, and compliance testing.

How to Choose the Right Burst Strength Tester: A Step-by-Step Guide

1. Define Your Application Requirements

Start by clarifying:

What type of material you’re testing (e.g., woven, knitted, paper, leather, carton)
Testing frequency (lab R&D vs. production line QC)
Required performance parameters (e.g., bursting strength in kPa or psi)

This ensures the equipment you select aligns with your operational and technical needs.

2. Select the Right Type of Tester

Hydraulic Burst Strength Tester: Offers high precision and consistency. Ideal for laboratory environments or high-end quality control setups. Suitable for fabrics, leather, paper, and packaging materials.
Pneumatic Burst Strength Tester: More portable and budget-friendly. Appropriate for basic applications or field inspections where ease of use is a priority.

3. Evaluate Operation and Maintenance Requirements

Hydraulic Systems: Deliver superior control and accuracy but may require trained personnel and regular maintenance.
Pneumatic Systems: Simpler in design, easier to operate, and require less maintenance. A good option for users with minimal technical expertise.

Choose equipment from a reliable manufacturer known for durable construction and after-sales support.

4. Consider Automation and Data Integration

Modern burst testers come with features like:

Touchscreen interfaces
Automated clamping and pressure application
Real-time test result output
USB or LAN connectivity for exporting data

These features can streamline testing workflows and improve traceability.

5. Set a Realistic Budget

Hydraulic burst testers are typically more expensive due to their precision and durability.
Pneumatic testers are cost-effective but may offer limited features.

Balance your budget with your operational priorities, and always prioritize long-term value over initial cost.
