This International Standard prescribes acceptance test methods for submersible mixers (hereafter “SM” or“mixer”) used for mixing in wastewater and other applications where at least one system component is a liquid.“Submersible mixer” is taken to mean a fully submersible aggregate consisting of a drive unit and an axial flowtype impeller, and optional parts, such as shrouds, supporting the basic functions.“Liquid” is taken to mean a body without capacity to accommodate shear stresses when at rest. This includessuspensions and dispersions (liquid/solid, gas/liquid and gas/liquid/solid), and non-Newtonian liquids, provided that a possible small yield stress does not prevent the liquid from flowing when agitated.
