• Phase II offers a vast array of different hardness test blocks for Rockwell, Brinell and Vickers scales, as well as Portable hardness testers
• Phase II hardness test blocks are made of high grade materials to insure unmatched accuracy and repeatability throughout the entire block.
• Phase II Hardness test block surfaces are precision ground and lapped to an average finish of less than 2uin.
• Hardness Test blocks always engineered to obtain highly sensitive and accurate readings.
• All Made in the USA hardness test blocks conform to current ASTM specifications
• Traceability to NIST is offered on HRC steel blocks only.
• Prestigious Accredited laboratory by A2LA and NVLA in the USA
