Bursting Strength Tester Manufacturer: Everything You Need to Know

Bursting Strength Tester Manufacturer: Regarding quality testing of packaging, paper, and textiles, there is one particular instrument that cannot be omitted under any circumstances – the bursting strength tester. As a manufacturer, quality engineer, or purchaser, knowledge of this device is crucial for the effectiveness of your manufacturing process and compliance with requirements. This detailed guide will introduce you to everything concerning the Bursting Strength Tester: definition, mechanism of operation, cost, specifications, and more.

What is Bursting Strength? Definition, Standards, and Real-World Applications

Bursting strength refers to the highest hydrostatic pressure that a substance can endure without rupturing or bursting. This is an important characteristic in mechanics that helps determine the durability and resilience of substances like paper, cardboard, corrugated boards, textiles, and geotextiles.
Bursting strength is measured in units of kilopascals (kPa) or kg per cm². In certain sectors, pounds per square inch (psi) is also employed for this measurement.
The bursting strength calculation is pretty simple:

• Bursting Strength = Force Applied / Area of Diaphragm

More precisely, it’s the pressure level at which the tested sample ruptures when subjected to a constant pressure load using a rubber diaphragm.
Some examples of bursting strength testing include:

• Testing corrugated box containers used in e-commerce logistics
• Checking paper and paperboard used for food-grade packaging products or pharmaceuticals
• Measuring the robustness of woven sacks used in the agriculture and chemical sectors
• Determining whether geotextiles and other technical fabrics are suitable for construction purposes

Bursting strength information guarantees that your packing material won’t break in transit or during storage.

Burst Test – Definition with Industry Examples

The Burst Test is a standard lab method used to measure the pressure at which a material will fail. Following is the process involved in conducting a burst test, along with industry examples.

• Sample Preparation – A piece of the material (such as paper, cloth, or board) is cut into standard dimensions and exposed to specific temperature and moisture conditions.
• Clamping – The material is tightly held in place over a rubber membrane by means of a clamp in the test head of the burst tester apparatus.
• Pressure Generation – The hydraulic fluid or glycerin is continuously supplied below the membrane to exert equal pressure over the material.
• Rupture – Pressure on the material continues to increase until it breaks open. The maximum pressure is recorded as the bursting strength of the material.

Examples in Industries:

• A box-making company conducts a burst test on each batch of raw boards before processing.
• A weaving plant conducts a burst test on polypropylene bags to ensure that they meet government-mandated bursting strength criteria to be used in packaging fertilizers.
• A paper company carries out burst tests on its products to meet export documentation requirements.

How Does a Burst Test Machine Work? Technical Overview with Testing Principles

The principle behind which the burst test machine works is based on the hydraulic pressure test method. The basic principle of work of this type of machine is the application of an evenly increasing hydraulic pressure to a clamped test material via a rubber membrane, up to its rupture.
Technical characteristics:

• This method of testing is performed with the use of a rubber membrane that expands under pressure evenly, creating the same stress on the tested materials, just like in reality.
• Hydraulic pressure is generated by a hydraulic pump, a manual or motorized one.
• The used rubber membrane is subject to constant monitoring, thanks to a pressure gauge or sensor.
• The pump is stopped automatically as soon as the material breaks, providing the exact result of the pressure achieved.

Modern models of burst test machines are fitted with microprocessors that help manage the test, storing and analyzing several results.

Bursting Strength Machine: Key Components, Features, and Working Mechanism

The essential components of a typical bursting strength tester include:

• Test Head with Rubber Diaphragm – The point of contact between the hydraulic system and the specimen under test
• Clamping Ring – Keeps the specimen secured in position without any sliding during the test process
• Hydraulic Cylinder and Pump – Creates and transfers pressure to the diaphragm
• Digital Readout – Displays instantaneous pressure readings and bursting values
• Control Panel – Permits user choice of test methods, units, and data storage options
• Printer Interface or Data Output Facility – Facilitates outputting results or connecting to a computer for data recording

Important considerations when selecting a bursting strength tester include:

• Large operating pressure range (can handle lightweight paper to dense corrugated board)
• Automatic zeroing and calibration capabilities
• Several measurement unit modes (kPa, kgf/cm², pounds per square inch)
• Conformity with global test specifications
• Robust construction of the instrument body

Industry Applications of Bursting Strength Testers (Packaging, Paper, Textile & More)

The application of the Bursting Strength Tester is quite common in many industries:

• Package Industries – Testing of corrugated boxes, cartons, and Kraft paper
• Paper & Pulp Industries – Raw Paper, newsprint, and other types of specialty papers
• Textile Industries – Fabric testing and testing of geotextiles and technical textiles
• Flexible Packaging – Burst test on pouches, laminate, and BOPP films
• Bags for Cement and Fertilizers – Compliance with BIS specification requirements
• Pharmaceutical Packaging – Blister pack material and secondary packaging validation

In whatever field the tester is being used, the application remains equally important from all aspects.

Q2. What is the Working of a Burst Tester? Explanation with Testing Mechanisms

Ans. At Effective Lab India, our burst tester machines operate using the tried and tested method of hydraulic pressure testing. With the help of our machine, the specimen material is securely mounted over the precisely designed rubber membrane that exists within the test head. Our machine’s internal hydraulic pump begins to apply constant increasing pressure against the underside of the membrane, causing it to inflate and exert equal pressure across the surface of the specimen — replicating the stress environment that the packaging/fabric material would be subjected to under normal circumstances. The process is continued until there is a rupture of the specimen material. The exact point of rupture is where the machine automatically shuts down the hydraulic pump and records the maximum pressure achieved at this particular moment as the bursting strength of the material.
