Workplace exposure. Assessment of sampler performance for measurement of airborne particle concentrations - Laboratory performance test based on determination of sampling efficiency Ingestion-build-134498 BS EN 4639-004 provides users1 Scope This European Standard specifies a laboratory performance test for samplers for the inhalable, thoracic and respirable aerosol fractions, based on determining the sampling efficiency curve of a candidate sampler at a minimum of nine particle sizes. It specifies methods for testing aerosol samplers under prescribed laboratory conditions in order to test whether the performance of a candidate sampler fulfils the requirements of EN 132051: 2014.
