What is the name of the scale that measures scratch resistance from 1 to 10?

• A. Brinell hardness scale
• B. Mohs Hardness Scale
• C. Vickers hardness scale
• D. Rockwell hardness scale

Answer: (B)

Scratch resistance is described by the Mohs hardness scale. This scale ranks minerals from 1 to 10 based on which substances can scratch others. A higher number means greater scratch resistance, with diamond at 10 being able to scratch all below it, and talc at 1 being easily scratched by many substances. It’s a qualitative, relative measure used mainly in mineralogy to identify minerals, not a precise engineering hardness value. Other hardness tests like Brinell, Vickers, and Rockwell measure indentation resistance with specific loads and indenter types, giving numerical values for materials such as metals. So the scale that measures scratch resistance from 1 to 10 is the Mohs hardness scale.
