Vickers hardness of ceramics and hardmetals

Description

• General description: Each unit of SRM 2831 contains 25 mm D × 9.5 mm disk with a nominal hardness of ~15.0 GPa (1530kgf/mm2), packaged in a wooden box. Every unit is certified individually and features a unique serial number, which is inscribed on the opposite (bottom)face of the disk in the format of the letter W followed by a hyphen and the disk number.SRM 2831_certSRM 2831_SDS
• Application: Vickers hardness of ceramicsand hard metals standard reference material (SRM) is intended for calibrating all hardness and microhardness testing machines. It involves creating a Vickers indentation and subsequently measuring it using a microscope.
• Features and Benefits: Accompanied with certified values for individual diagonal lengths, average diagonal length, and average Vickers hardness are provided.The NIST certificate is provided with expiration certificate, storage, handling,use, and maintenance instructions.
• Other Notes: Example analytes are listed below as a reference. Please download a current certificate at nist.gov/SRM for current analytes and certified values.
