This document presents recommendations and requirements for the determination of the average (spherical) equivalent diameter of nano-objects (particles, droplets or bubbles) dispersed in liquids using the technique of static multiple light scattering (DSML). The technique is applicable to a wide range of materials and does not require the dilution of concentrated samples.
