The approaches to calculating the mass fraction of mechanical impurities, as well as optical methods for direct and automatic determination of the counted concentration of particles, are described. The current regulatory documents, recommended instruments, methods for expressing the quantitative content of particles of various sizes, as well as the principles of encoding liquid purity, are considered. A comparison is made of three officially accepted methods in the Russian Federation for measuring the counted concentration of particles using automatic counters, their general and distinctive features are compared.
