Abstract. The article presents the results of work on the development of domestic mea­sures of par­ticle sizes in a liquid based on monodisperse polystyrene latex spheres. A method for the syn­thesis of a series of particle size measurements in a liquid by emulsion polyme­ri­zation with the use of sodium stearate as an emulsifier is proposed. Material measures of par­ticle sizes in a liquid with a nominal particle size value of 0.2 microns (MRH-0.2), 0.3 microns (MRH-0.3), 0.4 microns (MRH-0.4) and 0.5 microns (MRH-0.5) with values of relative error in reproducing the size (average diameter) of particles within ±5 % are produced.

Key words: particle, polystyrene latexes, microemulsion, suspension, GET 163-2020, material measure, colloidal particle.
