My hardness test requires 25mL of water, to which 5 drops of hardness indicator (isopropanol 23% w/w, triethanolamine 77% w/2) are added. This is supposed to turn the water red, and then a titrant is added drop by drop until it turns blue. This .
Hardness testing within the realm of materials testing. Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find qualitative relations to other material properties (e.g., strength, stiffness, density) or to the material behavior under certain stresses (e.g., abrasion .
