Development and application of standard enterprise samples in the practice of analytical laboratories

Abstract

The article presents the experience of development and application of enterprise standard samples (ESS) of monolithic and dispersed materials for spectral and chemical methods of steel analysis. The procedure for the development of ESS is described in detail: development of technical specifications for ESS in accordance with the requirements of GOST 8.315, preparation of ESS material, study of the uniformity of ESS material, establishment of metrological characteristics of ESS, preparation of a report on the development of ESS, verification of technical documentation for ESS and metrological examination of documentation, approval of ESS and its registration.
