Brinell Hardness test is best for measuring hardness of Grey C.I. casting consisting of soft flake graphite, iron & hard iron carbide. The main drawback of the Brinell test is the need to optically measure the indent size. This requires that the test point be finished well enough to make an ac- curate measurementPrepared by, (1) PATEL SHREY B .The diameter of the indentation left in the test material is measured with a low powered microscope. The diameter of the impression is the average of two readings at right angles. Brinell hardness number table can simplify the determination of the Brinell hardness number.

Shore Hardness Test: Specifically designed for elastomers and plastics, this test measures the material’s resistance to indentation using a standardized . Micro hardness testing involves forcing a diamond indenter with a specific geometry into the surface of a test piece under a small load, then using a microscope to measure the resulting indentation to determine the hardness; there are three main types of tests that differ by the indenter shape and how indentation size is measured; micro hardness testing is useful .
14. Knoop Test (Micro Hardness Test) Various micro hardness tests have been developed for application where it is necessary to determine the hardness of a very precise area of material, or where the material or surface layer is exceptionally thin. Special machine have been developed for this purpose. The location for this test is select in the high magnification. A .
There are several common hardness tests used to measure this property, including Brinell hardness testing, Rockwell hardness testing, and Vickers hardness testing. Brinell hardness testing involves indenting a material's surface with a hard steel or tungsten carbide ball under a heavy load and measuring the diameter of the indentation.

Dissolution testing predicts in vivo drug release profiles using basket or paddle apparatus under set conditions to simulate gastrointestinal fluids. These tests help ensure consistent dosing, sufficient strength, and controlled drug release.
5. Shore Test The Shore hardness is measured with an apparatus known as a Durometer and consequently is also known as “Durometer hardness”. The hardness value is determined by the penetration of the Durometer indenter foot into the sample. Because of the resilience of rubbers and plastics, the hardness reading my change over time - so the . Water Hardness Testing Strip.
