The regular issue of the “Almanac of Modern Metrology” is 2 (22) — the second issue of this year.
2020 is the anniversary year for VNIIFTRI, founded on February 18, 1955. The first issue of the Almanac of this year is dedicated to this event. The second issue also contains articles prepared for the anniversary date. They cover the issues of international comparisons of state standards, their use in the development of measuring equipment.
The problems of practical metrology in the development of food control methods are discussed. The traditional column “The founders of metrological directions” is represented by the luminaries of domestic metrology — Dmitry Nikolayevich Astrov and Semar Setovich Sekoyan.
