Bursting Strength Tester – Precision Fabric Testing Equipment for Textile Quality Control
When a fabric tears, rips, or gives way under pressure, it is not just a product failure — it is a trust failure. The Bursting Strength Tester from Amith Garment Services is engineered to prevent exactly that. This precision fabric testing instrument measures the force required to rupture a fabric specimen, giving textile manufacturers, quality control labs, and export houses verifiable data to ensure their fabrics meet industry benchmarks before a single metre leaves the floor.
Amith Garment Services has been supplying certified textile testing instruments to India's garment and fabric industry since 1999. Our Bursting Strength Tester Machine is built for durability, accuracy, and compliance — ready for use on day one.

What Is a Bursting Strength Tester?
A Bursting Strength Tester is a specialised fabric testing instrument that quantifies the maximum pressure or force a fabric can withstand before it ruptures. Unlike tensile testing — which applies force in a single direction — bursting strength testing applies omnidirectional force through a diaphragm, balloon, or steel ball, replicating real-world stress conditions such as elbow pressure on a sleeve or knee pressure on denim.
The result, expressed in kPa (kilopascals) or kgf/cm², gives manufacturers a single, standardised value to compare fabrics, validate suppliers, and confirm that finished goods meet specified strength thresholds before shipment or retail.
- Diaphragm (Pneumatic/Hydraulic) Method: A rubber diaphragm is inflated against the fabric until it bursts. Preferred for lightweight and stretch fabrics.
- Ball Burst (Steel Ball) Method: A steel ball is pressed through a clamped fabric specimen at a constant speed. More suitable for heavy-weight wovens and nonwovens.
Our Fabric Bursting Strength Tester supports both methods, making it a versatile addition to any textile quality control lab.
Why Is Bursting Strength Testing Important?
- Ensures consumer safety by verifying that fabrics will not fail prematurely under physical stress.
- Supports buyer compliance requirements for export-ready garments and industrial textiles.
- Provides objective data to resolve supplier disputes or quality rejection claims.
- Enables R&D teams to benchmark new fabric constructions against existing standards.
- Prevents costly product recalls by identifying weak fabrics early in the production cycle.
- Helps quality control labs issue third-party test reports that buyers and auditors accept.
How a Bursting Strength Tester Works – Step-by-Step
- Sample Preparation: Cut the fabric specimen to the required size and condition at standard atmospheric conditions.
- Clamping: Place the specimen centrally over the test aperture and clamp firmly.
- Diaphragm Inflation / Ball Loading: Inflate diaphragm or drive steel ball through specimen at constant speed.
- Force Application: Apply pressure/load until fabric ruptures.
- Automatic Stop: Machine stops automatically when burst is detected.
- Data Recording: Display peak bursting strength in kPa or kgf/cm².
- Multiple Tests: Repeat on minimum five specimens per sample.
- Report Generation: Compile results; export data via USB or PC interface.

Frequently Asked Questions:
What is a Bursting Strength Tester used for?
A Bursting Strength Tester measures the maximum pressure or force a fabric can withstand before it ruptures. It is widely used in textile testing laboratories, garment factories, and quality control departments to ensure fabrics meet required strength standards and buyer specifications.
What is the difference between the diaphragm method and the ball burst method?
The diaphragm method inflates a rubber diaphragm beneath the clamped fabric using pneumatic or hydraulic pressure, making it ideal for lightweight, stretch, and knitted fabrics. The ball burst method pushes a steel ball through the specimen at a controlled speed and is generally preferred for heavier woven fabrics and nonwovens.
Which standards does your Bursting Strength Tester comply with?
Our Bursting Strength Tester complies with international standards including ISO 13938-1, ISO 13938-2, ASTM D3786, BS EN ISO 13938, and IS 1966. Each machine is supplied with a calibration certificate traceable to national standards.
In what unit is bursting strength measured?
Bursting strength is commonly measured in kilopascals (kPa). Depending on the instrument, results can also be displayed in kgf/cm² or psi (pounds per square inch). Our digital models allow users to select their preferred unit of measurement.
How often does the rubber diaphragm need to be replaced?
The rubber diaphragm should be inspected regularly based on testing frequency and fabric type. For laboratories performing approximately 20–30 tests per day, replacement is generally recommended every 3–6 months or immediately if cracks, stiffness, or wear are observed.
Can I connect the Bursting Strength Tester to a computer for data logging?
Yes. Our digital Bursting Strength Tester models feature USB or RS232 connectivity, allowing test data to be exported directly to a computer for quality management systems, spreadsheets, or automated report generation.
Does Amith Garment Services provide installation and training?
Yes. Our Bangalore-based service team provides complete on-site installation, commissioning, operator training, and guidance to ensure your staff can confidently operate and maintain the Bursting Strength Tester from day one.
Do you offer calibration services for existing Bursting Strength Testers?
Yes. Amith Garment Services offers professional annual calibration services for Bursting Strength Testers, including equipment purchased from other suppliers. Our calibration services help maintain testing accuracy and compliance with industry standards.
What fabrics can be tested with this equipment?
The Bursting Strength Tester is suitable for testing woven fabrics, knitted fabrics, nonwovens, technical textiles, geotextiles, denim, medical textiles, filter media, and other engineered textile materials. The appropriate model depends on the fabric weight and construction.
