ISO has just released a new standard, ISO/TS 12025:2012, “Nanomaterials – Quantification of nano-object release from powders by generation of aerosols,” and it’s available from Document Center Inc. now.
The emissions or release of nano-objects into the surrounding air from powdered nanostructured materials resulting from handling are an important consideration in the design and operation of many industrial processes. Released nano-objects may affect human health and the environment, depending on the nature and quantity of the nanomaterial. It is therefore important to obtain data about the propensity of nanomaterials to release nano-objects, thereby allowing exposure to be evaluated, controlled and minimized.
ISO/TS 12025 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.
ISO/TS 12025:2012 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.
