DIN CEN ISO/TS 12025; DIN SPEC 52406:2015-07
Nanomaterials - Quantification of nano-object release from powders by generation of aerosols (ISO/TS 12025:2012); German version CEN ISO/TS 12025:2015

Title (German)

Nanomaterialien - Quantifizierung der Freisetzung von Nanoobjekten aus Pulvern durch Aerosolerzeugung (ISO/TS 12025:2012); Deutsche Fassung CEN ISO/TS 12025:2015




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. 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. 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 does not include the characterization of particle sizes within the powder. Tribological methods are excluded where direct mechanical friction is applied to grind or abrade the material. The committee responsible for this DIN SPEC is NA 062-08-17-02 UA "Prüfverfahren" ("Test methods") at Standards Committee Materials Testing (NMP) at DIN.
