Contemporary x-ray wavelength metrology and traceability [PDF]

Radiation Physics and Chemistry, 2020
We report recent advances in absolute x-ray wavelength metrology in the context of producing modern standard reference data. Primary x-ray wavelength standards are produced today using diffraction spectrometers using crystal optics arranged to be operated in dispersive and non-dispersive geometries, giving natural-line-width limited profiles with high ...

Role and responsibilities of laboratory medicine specialists in the verification of metrological traceability of in vitro medical diagnostics [PDF]

Journal of Medical Biochemistry, 2015
To be accurate and equivalent, laboratory results should be traceable to higher-order references. Furthermore, their quality should fulfill acceptable measurement uncertainty as defined to fit the intended clinical use.

Traceable 3D imaging metrology

SPIE Proceedings, 2007
This paper summarizes the causes of uncertainty in 3D data measurement, some basic theory of 3D imaging that explains the origin of some of these causes, and, describes the properties and performances of a 100 square meter facility to perform research in traceable 3D imaging metrology. Built in 2006, the laboratory space allows accurate measurements of

Analysis of Metrological Requirements in Occupational Health and Safety Regulations Related to the Emerging Risk of Exposure to Vibrations

Applied Sciences, 2020
In occupational exposure to vibration, the risk assessment process is defined through a regulatory framework that presents some relevant metrological problems. This framework considers methods based on estimation and on measurements.

Metrological traceability in clinical laboratory

Jornal Brasileiro de Patologia e Medicina Laboratorial, 2016
Introduction: Metrological traceability is a little-known and little-discussed metrology theme in clinical laboratories, although it is the basis for comparable results. It is associated with certified reference material (CRM) and reference method (RMet).
