Abrasives laboratories may also do the following tests:

Hardness Testing: Measures the resistance of the abrasive material to penetration or indentation often using scales such as Mohs for minerals or Rockwell for industrial materials. Testing
Grain Size Analysis: Determines the size distribution of abrasive particles which influences the material removal rate and surface finish. Testing
Friability Testing: Assesses how readily the abrasive grains fracture affecting their cutting efficiency and lifespan. Testing
Shape Analysis: Evaluates the shape and profile of abrasive grains which can impact performance and the finish of the workpiece. Testing
Adhesion Testing for Coated Abrasives: Measures the strength of the bond between the abrasive grains and their backing material. Testing
