60 Years of Quality Control of Mineral Raw Materials Laboratory Tests

Scientific council on analytical procedures will celebrate its 60th anniversary in 2024. The article notes the invaluable contribution of the founders of the NSAM to the creation and development of a quality management system for analytical work in the geological industry, ensuring the reliability and comparability of laboratory tests of mineral raw materials. A review of directive documents that establish requirements for the main stages of analytical work (from sampling to all types of quality control of analysis of rocks and ores) is provided in the article. The key aspects of the quality management system for analytical work have been considered: measurement techniques, certified reference materials, interlaboratory comparison, confirmation of the competence of laboratories.
