Mullen bursting strength tester: 12 Interesting Facts

Here are 12 interesting facts about the Mullen bursting strength tester:

1. The Mullen bursting strength tester is a device used to determine the burst resistance of paper, paperboard, and other sheet materials.

2. It measures the maximum pressure or force required to rupture or burst a specimen using a hydraulic system.

3. The Mullen tester is named after its inventor, Stephen Mullen, who developed it in the early 20th century.

4. This testing method is widely used in the packaging industry to ensure the durability and strength of materials used in packaging.

5. The bursting strength is measured in pounds per square inch (psi) or kilopascals (kPa), depending on the region.

6. The Mullen tester consists of a pressure chamber, hydraulic system, pressure gauge, and clamping mechanism to hold the specimen securely.

7. The test procedure involves placing the specimen in the tester, increasing the pressure until it bursts, and recording the maximum pressure sustained.

8. The bursting strength of a material indicates its ability to withstand external forces such as compression, impact, or stacking during transportation and storage.

9. Different types of instruments are available, including analog and digital versions, with varying pressure capacities to accommodate different testing requirements.

10. The results obtained from the tester help manufacturers determine the quality and suitability of materials for specific packaging applications.

11. Bursting strength testing is governed by various international standards, such as ASTM D3786 and ISO 2758, which provide guidelines for performing the test.

12. In addition to burst resistance testing, the Mullen tester can also be used to evaluate the quality of corrugated boards, plastic films, textiles, and other materials.
