Describes guidance on the measurement of the size distributions of particles dispersed in an electrolyte solution using the electrical sensing zone method. It does not address the specific requirements of the particle size measurement of specific materials. The method described in the Standard measures particle volumes and reports in the range from 0.6 ¿¿m to 1600 ¿¿m. This Standard is identical with and has been reproduced from ISO 13319:2000.
