BS PD CEN ISO/TS 12025:2015

BS PD CEN ISO/TS 12025:2015 provides methodology for the quantification of nano-object release frompowders as a result of treatment, ranging from handling to high energy dispersion, by measuring aerosolsliberated after a defined aerosolization procedure. In addition to information in terms of mass, theaerosol is characterized for particle concentrations and size distributions. This Technical Specificationprovides information on factors to be considered when selecting from the available methods for powdersampling and treatment procedures and specifies minimum requirements for test sample preparation,test protocol development, measuring particle release and reporting data. In order to characterize thefull size range of particles generated, the measurement of nano-objects as well as agglomerates andaggregates 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.Cross References:ISO/TS 27687:2008ISO/TS 80004-1EN 15051:2006EN 481:1993 ISO/TR 27628:2007ISO 21501-1:2009ISO 21501-4:2007ISO 13320:2009ISO 27891ISO 15900:2009ISO 15901-1:2005ISO/TS 80004-4:2011ISO/TR 13121:2011ISO/TR 22971:2005ISO 14488:2007Incorporates the following:Corrigendum, July 2015
