What is ISO/TS 12025 about?
ISO/TS 12025 describes methods for the quantification of nano-objects released from powders because of treatment. This ranges from handling to high energy dispersion, by measuring aerosols liberated after a defined aerosolization procedure. Particle number concentration and size distribution of the aerosol are measured, and the mass concentration is derived. ISO/TS 12025 provides information on factors to be considered when selecting among 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. To characterize the full-size range of particles generated, the measurement of nano-objects, as well as agglomerates and aggregates, are addressed in this document. Note: ISO/TS 12025 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.and The quantification of the release of nano-objects from powders described in this document cannot be used as a substitute for dustiness testing or for a health-related risk assessment.
