Standards fabrication to providing metrological traceability in micromass and nanoforce measurements results
Abstract
Some of the more sensitive weighing equipment available nowadays has its repeatability close to tenth of microgram. OIML characterize mass standards bigger them 1 mg, so in this range doesn’t exist direct traceability to the kg prototype. The ASTM has a characterization of mass standard 50, 100, 200 e 500 micrograms. This work have a purpose of providing traceability to mass measurement in microgram scale (nanonewton scale in force) with the confection and calibration of a standard weights collection. At this time were studied two materials, Tungsten and MetGlass2705M (MetGlass), and produced 12 mass standards.
