The bursting strength of fabric and other related products is an important property that must be tested thoroughly. It is the measure of the maximum force needed to rupture a material. Bursting strength is essential for determining the ability of material against bursting forces.

Paper and cardboard products must be able to withstand the force exerted on them during use, such as when it is folded, bent, compressed, or handled. Testing the bursting strength of these products can help identify potential issues before they become problems and costly mistakes. To ensure that your materials can withstand the bursting forces, we at Presto have designed one of the high-quality lab testing instruments known as a bursting strength testerWe offer different models of bursting strength testers and one of the widely used is the bursting tester digital model.  

This is one of the high-quality laboratory testing equipment that has been designed to test the strength of materials against bursting forces. However, in order to get accurate results from a bursting strength tester, there are certain tips and techniques you should follow. In this blog, we’ll be discussing how to ensure you get the most accurate results when using a bursting strength tester. But before that, let’s focus on the factors that may influence the accuracy of bursting strength results.

Factors influencing the accuracy of bursting strength test results

The bursting strength machine is an important testing instrument for the paper & packaging industry, as it is used to evaluate the integrity and durability of the material used in corrugated boxes. The Presto bursting strength tester works by applying hydraulic pressure onto a circular area of the sample of the corrugated board under test, with a digital indicator measuring the force needed to burst the board.

This pressure can range from 0 to 40 kg/square cm. Since burst strength testing provides a measure of the maximum stress a package can withstand, it is a great tool to ensure that the packages used in shipping and storing products are of the highest quality, as they need to be able to withstand any bumps and bruises they may encounter during transportation.

By testing the strength of the corrugated boxes, manufacturers can make sure the boxes are strong enough to protect their products from damage and meet the expectations of their customers.

But there are certain factors that may affect the accuracy of the testing results. Below we have mentioned them:

  • Inaccurate placement of the sample is one of the most important factors influencing testing results when it comes to a bursting strength tester. If the sample is placed incorrectly on the machine platen, then the results will be inaccurate due to incorrect pressure distribution over the surface of the sample. Thus, it is important for the manufacturers to place the specimen accurately to get highly accurate lab testing results.
  • Glycerin leakage is an important factor that can influence the results of the bursting strength test procedure of the materials. The leakage may be caused due to the loosening of the lower jaw, the diaphragm displaced or busted. Thus, it is important for manufacturers to test the glycerin leakage to avoid inaccuracy of testing results.
  • Obstructions at the testing area are another important factor that can influence the results of testing the bursting strength of the materials. This can cause the pressure to be uneven and the results of the test will not be accurate. It is important to make sure that there are no obstructions that could affect the accuracy of the test in any way.

These are some of the factors that may affect the bursting strength of the materials. Keep these factors in mind when conducting your next bursting strength test and you’ll be sure to get the most accurate results possible. Presto ASTM D 3786 Burst Strength Tester for paper and fiberboard material provides accuracy in testing results in every time. Now, let us discuss more Presto bursting strength tester machine.
