The articles in the sixth issue of the Al’manac of Modern Metrolgy deal with the topic of physicochemical measurements and address important issues of metrological support for these measurements in the interest of the national economy. The articles are based on the concepts, results of investigations, and conclusions from the papers presented at the all-Russian scientific-technical conference “Metrology of physicochemical measurements” held in Mendeleevo in October 2015 and organized by Rosstandart, VNIIFTRI and ZAO Innovatsionnye technologii “Test-Pribor”. The conference papers were recommended for publication as articles in the Al’manac of Modern Metrolgy.
