Risk Rating Assessment

Risk ratings and scaling can show where additional resources are required. In our discussion, we'll focus on rating risks using probability of occurrence and severity of consequences scales. Because risk identifiion and rating establish priorities, this assessment should be incorporated early in the experimental process.

Mohs Hardness Scale

 · The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.
