📋 Tender Overview
Ural Research Institute of Metrology - branch of VNIIM im. D.I. Mendeleev in 2020 completed tests of 11 new types of standard samples of surface density and thickness of one- and two-layer coatings. Based on the results of testing all samples were approved by Rosstandart.As told in the laboratory of metrology of thermometry and surface density of UNIIM standard samples CRM created at the institute are intended for metrological support of work using modern X-ray fluorescence meters. Such measurements are in demand in particular in the production of various electronics where it is necessary to control the surface density and thickness of coatings.With the help of CRM it is possible to ensure the accuracy of the measuring devices to certify the methods for measuring the surface density and thickness of galvanized coatings and to carry out interlaboratory comparison tests in this area of measurements.Standard samples are represented by disc-shaped bases of copper or steel on which respectively gold cadmium nickel tin silver and zinc coatings are applied with a nickel silver or copper sublayer. The main metrological and technical characteristics of CRMs can be found in FSIS Arshin.
