Correct Procedure to Conduct Bursting Strength Test
Bursting Strength is one of the most important indicators for strength of different materials such as paper, fabric, and cardboard. In any industry, the strength of materials is a vital factor that is required for the better quality of the products. The manufacturers of products such as fabrics, packaging materials etc. need to ensure that they are providing the products with proper strength so that they could ensure the best quality of the products. When it comes to ensuring the best strength of products and materials, the manufacturers need to run various tests that can help them analyse their behaviour when the strength of such materials is being tested. Bursting strength test is one such test conducted in industrial laboratories to study the strength of various materials.
Bursting Strength Test
Bursting strength test or Mullen test is a widely conducted test that is conducted to determine the maximum amount of force that a material can bear without rupture and damage. The direction of the application of the force is perpendicular to the plane of the material. Generally, the force is applied on the specimen using hydraulic arrangement and a diaphragm. The bursting strength of the materials gives an idea of the amount of force that it can bear without facing failure.
Procedure to Conduct Bursting Strength Test
The Bursting strength test is conducted through a testing instrument called bursting strength tester. Bursting strength tester uses rubber diaphragm and lab grade glycerine to exert the bursting pressure on the specimen.
To conduct the tests, first of all, a circular disc of the specimen is to cut out of the sample. Typically, the diameter of the circular disc is supposed to be bigger than the clamp so that the specimen is properly clamped. The clamps are also serrated with bevelled grooves to prevent any chances of slippage.
Once the specimen is placed and clamped properly, the test procedure is started. The force is applied on the specimen by the diaphragm and the amount of force applied is shown on the digital display. As soon as the specimen ruptures, the application of force is stopped. The reading on the screen gives the actual bursting strength of the specimen. This bursting strength tells about the ability of the material to bear the impact that will be exerted on them.
The manufacturers in industries such as packaging industries need this bursting strength to estimate the strength and efficiency of the packaging containers that they will be providing their clients.
