A regular publication of “Almanac of the Modern Metrology”, №14-2018, is devoted to mainly physical-chemical measurements. Importance of this kind of measurements is once again confirmed by the held last year scientific and technical conference on this matter.
The best papers presented at conference upon decision of the Organization Committee, formed the basis of the written and placed in “Almanac” articles. They are devoted to the standard base in the field of physical, chemical and electrical measurements, description of state and working standards, standard titres, standard samples, measuring devices. The results of researches, calculations, factor analysis influencing the measurement accuracy, some arising from it decisions are provided. The article in “Almanac” devoted to aerosol study is of special importance and fundamentality.
