This standard specifies various performance measurement methods for water-soluble quenching media of polymers, including Appearance, solids by volume, density, kinematic viscosity, Refractive index, freezing point, cloud point, acid alkalinity, diluent chill down Linear dispersion and rust prevention test. A series of normative documents are cited, such as petroleum product freezing point determination method, chemical reagent Refractive index determination general method, etc. Appearance measurement method is mainly the Appearance mass of the test sample, and the instruments used include Glass measuringflask, mercury-filledthermometer and Glass beaker. Determination of solids by volume involves heating the sample to constant weight and determining solids by volume by mass change. Before using this standard, the user should ensure that appropriate safety and protective measures are in place and determine the applicability of relevant regulations.
