Auto Bursting Strength Test Procedure

What is bursting strength tester:

Bursting strength tester principle: the tensile strength of fabric can be measured when the sample is under continuous pressure until suddenly burst. The definition of bursting machine is a kind of textile burst testing equipment to determine the bursting strength of knitted fabric, fabric, paper, and so on. It can accurately control the burst time by intelligent algorithm and support PC control software. We can calculation of bursting strength by the test results according to bursting strength calculation formula and print it to meet the requirements of different standards. In order to provide customers with simple and understandable operation method, bursting strength tester manual is enclosed, the detailed burst pressure test procedure and burst test specification are provided.

(For more information in detail, please see bursting strength tester Wikipedia)

Bursting strength calculation formula:

Bursting strength: (kN/m2)= A-B

(Attention: 1Mpa=1000kN/m2; Bursting strength unit: kN/m2)

In the equation:

A – The average of burst strength, kN/m2

B – The number of diaphragm calibration, kN/m2

Bursting strength tester calibration:

  1. Doing the first test with the sample, and doing another test with calibration plate, we should set the same parameters in order to compare both results of them.
  2. In analyzing two results, if they are the same, the burst test machine needn’t calibrate. On the contrary, it needs a calibration.
  3. If the first test result displays 70kPa, but the second one displays 60kPa, there is 10kPa difference between two test results.
  4. Adjusting the 10kPa calibration pressure, and then touch “enter” button, it will display the pressure as 70kPa, and the calibration is finished.


Effect and classification of Mullen burst strength machine

Mullen bursting strength definition: Bursting strength refers to the strength when the sample is destroyed under the external pressure. When the sample is damaged, the pressure of transverse and longitudinal is often received at the same time, especially for some knitwear, the pressure in each direction affects each other. The bursting strength testing machine can test the bursting strength for fabric in an all-round way and get the bursting strength fabric we need.

Bursting strength test is mainly used in the textile industry and carton packaging. The common burst pressure testing machines are bursting strength tester of a corrugated box for testing the bursting strength of paper or carboard, hydraulic burst strength tester, barometric bursting strength tester, and Mullen bursting strength tester. Different types of bursting strength machine price are also different.
