Buehler obtains ISO certification for Vickers and Knoop reference hardness testing blocks

The Buehler Wilson® Reference Block Laboratory in Binghamton, N.Y., has achieved accreditation to ISO/IEC 17025 by American Association for Laboratory Accreditation (A2LA) for Rockwell, Knoop, Vickers, and Brinell hardness test blocks and indenters. A2LA is in full conformance with ISO and IEC standards, including ISO/IEC 17025.

The testers used in the calibration process undergo a stringent monitoring process using NIST-traceable devices, and Buehler conducts 100 percent inspection to ensure that every test block meets the physical requirements of ASTM. The laboratory then calibrates the blocks according to Rockwell, Vickers, and Brinell scales, complying with ASTM and ISO calibration standards.
