NEW NIST PRACTICE GUIDE ON ROCKWELL HARDNESS TESTING AVAILABLE The NIST Recommended Practice Guide: Rockwell Hardness Measurement of Metallic Materials
WANTED: MEASUREMENTS WITH GOOD REFERENCES In nearly all types of activities-be they related to manufacturing, finance, health, regulatory affairs or even sports-people and organizations are becoming sticklers for measurement uncertainty. NIST, the nation’s measurement authority, has responded to this growing customer need for demonstrable uncertainty. It has created an on-line resource— www.nis...
متن کاملCapability in Rockwell C Scale Hardness
A measurement system is capable if it produces measurements with uncertainties small enough for demonstration of compliance with product specifications. To establish the capability of a system for Rock-well C scale hardness, one must assess measurement uncertainty and, when hardness is only an indicator, quantify the relation between hardness and the product property of real interest. The uncer...

15 صفحه اولAnnealing of Co-Cr dental alloy: effects on nanostructure and Rockwell hardness
PURPOSE The aim of the study was to evaluate the effect of annealing on the nanostructure and hardness of Co-Cr metal ceramic samples that were fabricated with a direct metal laser sintering (DMLS) technique. MATERIALS AND METHODS Five groups of Co-Cr dental alloy samples were manufactured in a rectangular form measuring 4 × 2 × 2 mm. Samples fabricated by a conventional casting technique (Gr...
متن کاملDeposition of carbon nanotubes in commonly used sample filter media
There is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes. Existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...
