Material Testing Machines

material testing to check the durability and integrity

Any successful business organization would have its foundation strong and sound. To ensure that, they check for what they are selling and how solid is the quality of the products. Many rely on material testing to check the durability and integrity of their products. As a result, the material testing industry has been on a hiatus.

Test labs use material testing machines to derive the conclusion whether the products would last or not. Several tests are applied depending on the product, its use and its properties and nature. Bend test, bond test, compression/stress test, fatigue test, tensile test and many among others.

Different types of machines are used for different tests, for instance,

  • To test compression: A compression test machine is used to test a material's reaction when induced with tension, crushing or squashing. The goal of the compression test is to examine the product's behavior when subjected to variables like strain, stress and deformation. The most common machines used are:
  1. ISO 844 Compressive Strength of Rigid Cellular Plastics

  2. ISO 604 Compressive Plastics Testing Equipment

  3. ASTM E9 Compression Testing of Metallic Materials at Room Temperature

  4. ASTM D3574 Testing for Flexible Cellular Urethane Foams

  • To test bending: To test the ductility and resistivity to fracture of a material, it is subjected to a deformation at its core point creating a concave depression in it. Bend testing machines are used for such tasks. Bend tests are usually done to metals and metallic products but on occasion can also be done t plastics. Some standard machines include:

  1. IPC JEDEC 9702 Monotonic Bend Testing Interconnects

  2. ISO 6782 Flexural Strength Dentistry Ceramics

  3. ISO 178 3 Point Bend of Plastics- Flexural Test Machines and Equipments

  • Universal test machines: Providing a modification altogether, certain electromechanical test machines which can perform an array of quasi-static tension are called universal testing machines. These machines are equipped to apply large KiloNeutons of force to test the materials. Certain examples of Universal testing machines are:

  1. 100 Family Single Column Electromechanical Universal test Machine

  2. 110 C Type Electromechanical Universal test Machine

  3. 120 Family Dual Column Electromechanical Universal test Machine and many more

The use of Universal testing machines can vary depending upon the product you are testing. Since it holds a large amount of force within, depending upon the material the required force should be applied, for instance when applying,

  • 0-5 KN: 100 Series Universal Test Machines should be used

  • 0-5 KN with extensive elongation: 200 Series Universal Test Machines should be used

  • 5-600 KN dual column: 300 Series Universal Test Machines should be used

To check for the defects in the materials and the end-product, material testing is very important and plays a vital role in determining the durability, integrity and reliability of the product.
