Hardness Test Block - 15Y Superficial Rockwell (HR15Y)

Hardness Test Block - 15Y Superficial Rockwell (HR15Y)

For the precise hardness characterization of exceptionally soft materials, the Rockwell hardness HR15Y scale is the designated standard. It is specifically designed for applications where even traditional Rockwell scales would produce invalid results due to excessive indentation or material breakthrough. This method employs a 15 Kg load with a large 1/2 inch ball penetrator, making it the ideal choice for testing soft bearing metals like brass and certain dense polymers where measurement integrity is paramount.

Validating the consistency of these soft materials is critical for their functional performance. Therefore, obtaining accurate HR15Y hardness data is fundamental to any rigorous quality assurance program for these specialized products. Confidence in these measurements is established through the use of certified reference blocks. A fully traceable HR15Y hardness block ensures your superficial hardness tester is calibrated correctly, providing the metrological assurance required to verify that your materials meet strict engineering specifications.
