Wilson® UH4000 Universal Hardness Tester
Hardness Test Blocks
Wilson sets the industry standard for hardness test blocks-crafted from top-quality materials for unmatched uniformity and repeatability. Our wide range includes scales for Rockwell®, Brinell, Knoop, and Vickers testing, all calibrated in our accredited ISO-IEC 17025 lab in Binghamton, NY. Calibration sets are available for most Rockwell scales, ensuring ultimate accuracy and performance. We collaborate directly with mills to specify chemical composition, and perform all machining processes in-house, guaranteeing 100% inspection for ASTM compliance in thickness, flatness, parallelism, and surface roughness.
Wilson® Vickers Knoop Hardness Test Blocks
Available in a range of HV and HK scales in accordance with ASTM E92, ISO 6507-3 (Vickers), JIS B 7737 (Vickers), ISO 4545-3 (Knoop), and JIS B 7734 (Knoop).

Hardness Testing Fundamentals
Vickers
Knoop
Similar to Vickers hardness testing, Knoop uses a diamond indenter. However, instead of square indents, Knoop indenters are rhombohedral-shaped, creating an elongated indent, with the longer diagonal seven times the shorter. Unlike Vickers, only the long diagonal is measured, saving time. Knoop indents can be placed closer together, advantageous for testing thin layers. However, HK varies with load, and conversions to other scales are reliable only at the standard load (500gf).
Rockwell
Brinell
Brinell hardness testing is widely used for large parts like engine castings and piping, where high loads and large indents offer precise hardness determination. The method’s versatility is constrained by the indenter ball’s deformation with harder materials, and the importance of load and ball diameter ratios for accurate results.
