DIN ISO/TS 12025:2013-09

This Technical Specification provides methodology for the quantification of nano-object release from powders as a result of treatment, ranging from handling to high energy dispersion, by measuring aerosols liberated after a defined aerosolization procedure. In addition to information in terms of mass, the aerosol is characterized for particle concentrations and size distributions. In order to characterize the full size range of particles generated, the measurement of nano-objects as well as agglomerates and aggregates is recommended in this Technical Specification. This Technical Specification provides information on factors to be considered when selecting from the available methods for powder sampling and treatment procedures and specifies minimum requirements for test sample preparation, test protocol development, measuring particle release and reporting data. This International Technical Specification ISO/TS 12025 has been prepared by Technical Committee ISO/TC 229 "Nanotechnologies". This translation has been prepared by Subcommittee NA 062-08-17-02 UA "Prüfverfahren" ("Test methods") of Working Committee NA 062-08-17 AA "Nanotechnologien" ("Nanotechnologies") of the Materials Testing Standards Committee (NMP). Agreement with the International Technical Specification is thus documented by the committee.
