Test Blocks and Indenters

Wilson^® Hardness provides a comprehensive range of hardness test blocks and indenters for Rockwell, Vickers, Knoop, and Brinell applications. Certified to a range of international standards including ASTM and ISO, we manufacture test blocks in-house to ensure the highest quality test reference standards available. Test blocks and indenters are certified using the latest standardization and optical measuring technology. We operate our own calibration laboratory, traceable to NIST and are accredited to ISO/IEC 17025 by NVLAP^®.

Rockwell hardness test blocks have a certified nominal hardness value, and can quickly identify an out-of-tolerance condition during daily verifications. Best practices recommend that high, middle and low range of the given scale be verified. A comprehensive selection of certified Rockwell diamond and ball indenters is also available to meet a wide range of application and testing needs.	Standardized reference test blocks and certified carbide ball indenters provide a relatively easy and inexpensive means of verifying tester, indenter and total Brinell system performance. We offer a comprehensive selection of standard nominal hardness ranges and gram load configurations, as well as custom Brinell test blocks calibrated to your test specifications.	Daily indirect block verification is recommended as a means of validating tester performance and compliance with standards, as well as accuracy of the total system. Testing should be performed throughout the working range of the tester at the nominal hardness value ranges and forces which are utilized.
