Definitions for "Hardness test"
Hardness test: A test designed to assess the resistance to penetration from a load. Typically used a quality control test for thermal spray coatings.
A test used to determine the relative resistance to indentation or displacement of metals by pressure, or by resistance to abrasion. Common methods of testing include Brinell, Rockwell, and Vickers tests.
A test to measure a particular material's resistance to indentation. Tests for sheet metal include Rockwell, Rockwell Superficial, Tukon and Vickers.
