How to choose textile bursting strength tester:Pneumatic or hydraulic?

DARONG Company is the initiator of China’s national standard for textile bursting strength testing. DARONG is also the inventor of the first pneumatic bursting strength tester in China. In this article, let’s elaborate on “Choosing between pneumatic or hydraulic textile bursting strength tester”. Hope to help customers make informed choices based on their needs.

Working Principle of Pneumatic and Hydraulic Bursting Strength Tester

The pneumatic tester generates bursting force using compressed air by applying air pressure to the specimen to test its bursting strength and expansion properties. On the other hand, the hydraulic tester utilizes a hydraulic system, typically using glycerin as the working medium, to apply pressure for testing.

Advantages in Bursting Strength Testing Process

Compared to the hydraulic tester, the pneumatic tester offers several advantages during the testing process. As it operates using compressed air instead of hydraulic pressure, the pneumatic tester is easier to maintain and clean. Unlike the hydraulic tester that may experience glycerin leakage after the specimen bursts, the pneumatic tester does not have any liquid leakage, resulting in a cleaner testing environment.

Size and Flexibility

Pneumatic testers are generally designed to be compact and lightweight since they do not require the volume and complexity of a hydraulic system. This makes them more popular in laboratory environments, especially for frequent mobility or limited space situations.

Standards and Selection

Some standards have specific requirements regarding the range of bursting strength testing. Within certain ranges, customers have the option to choose between a pneumatic bursting strength tester or a hydraulic tester. Existing data suggests that there is no significant difference in bursting strength data between hydraulic and pneumatic testers when the pressure does not exceed 800 kPa. This pressure range covers the performance level of most common garments. However, for special textile testing with high-pressure requirements, a hydraulic tester is still necessary.

Therefore, the choice between a hydraulic or pneumatic tester depends on the customer’s individual standards and needs.
