Apparatus: 1.The penetration test can also monitor hardness over temperatures that the soap may be subjected to during transportation and storage. Test temperatures must therefore be reported in the results. The soap penetration test can also indicate whether there are trapped air bubbles or a grainy texture seen as fluctuations in force as the probe comes .Leeb Hardness Test. The Leeb hardness test is a non-destructive and portable method used primarily for metals. It involves a spring-loaded end with a spherical or conical indenter. The end that makes contact with the material is released, and the rebound velocity is measured after striking the material's surface.
Brinell Hardness Test. Similar to the Rockwell hardness test, a Brinell hardness test uses a heavier test metal and creates a larger indentation in the sample material, and measures only the indentation. .
