The regular issue of the “Almanac of Modern Metrology” (No. 3 (19) 2019) — the third issue of this year is mainly devoted to the development of the statutory and regulatory, scientific and methodological bases, their main elements. The directions of improvement and development of reference standards to ensure the uniformity of measurements, development of new modern measurement methods, projects of changing the standards used are highlighted.
Attention is also paid to the testing of reference materials for the purpose of type approval as one of the forms of state regulation of ensuring the uniformity of measurements.
The role of comparisons in the improvement of state standards is emphasized, conclusions are made on the basis of the results of international comparisons.
Special sections of the journal are dedicated sections to the founders of metrological directions.
