How to handle the report of bursting displacement detection? According to the corresponding standards, the 100% inspection team develops relevant plans for top breaking displacement detection, conducts testing and analysis on sample related items, and issues authoritative and effective testing reports

Common bursting test methods:

1. Hydraulic method

The testing principle of hydraulic method is to clamp a certain area of sample onto an extensible membrane and apply liquid pressure below the membrane.

. Then, increase the volume of the liquid at a constant rate, causing the diaphragm and sample to expand until the sample ruptures, and measure the bursting strength and bursting expansion. The commonly used hydraulic bursting strength machines include the MullenC and MullenA bursting strength machines, both of which use the liquid pressure of glycerol to produce a swelling effect through an elastic film to complete the test. Their main difference lies in the different ranges between the MullenC and MullenA models. The MullenC has a range of 2 to 200PSI, while the MullenA model has a range of 10 to 500PSI. But when using, only 15% -75% of the full scale can be tested, otherwise it is easy to compress and explode the elastic film. For some high elastic fabrics, the customer requests to puncture the fabric. If the fabric cannot be punctured on MullenC, it needs to be taken to MullenA for puncture. The commonly used standard methods for Mullen type hydraulic bursting strength machines include American and European standards. The American standard uses ASTMD3786, with the unit being PSI; The European standard uses ISO13938-1, which is measured in KPA

2. Air pressure method

The testing principle of the air pressure method is to clamp the sample onto an extensible membrane and apply gas pressure below the membrane. Then, increase the gas volume at a constant rate to expand the diaphragm and specimen until the specimen ruptures, and measure the bursting strength and bursting expansion. The commonly used pneumatic fabric bursting strength tester is the Truburst pneumatic bursting strength tester, which uses an air pump to provide gas pressure and uses an elastic film to expand and break the fabric. It consists of three main parts: an air pump, a tester, and a printer. The tester also includes a test cup, an elastic film safety cover, and so on. There are two commonly used test cups. A large cup with an area of 50 square centimeters and a permissible displacement of 70.50 millimeters, with a testing time of 20 ± 5 seconds; A small cup with an area of 7.3 square centimeters and an allowable displacement of 22.50 millimeters; The testing time is also 20 ± 5 seconds. There are many standard methods for testing the bursting strength of fabrics using Truburst air pressure, but among the commonly used methods, the American standard uses ASTMD3786, with the unit being PSI; The European standard uses ISO13938-2, with the unit being KPA
