Air cleaning equipment — Test aerosols for filter evaluation — Salt aerosols reproducing the accumulation mode in typical urban atmospheres

Апстракт

This document specifies the properties, designation, generation principle, particle size distribution, concentration stability, chemical composition, and verification of a laboratory-generated salt aerosol intended to reproduce the sub-micrometre accumulation-mode fraction of typical urban atmospheres.
This document is intended for use in laboratory evaluation, ageing, conditioning, or loading of air filters and air-cleaning equipment, including general ventilation filters evaluated in conjunction with the ISO 16890 series.
This document does not specify a complete ageing procedure, a filter loading endpoint, an efficiency test method, an energy-use calculation, a filter classification method, a life-cycle cost method, or a calibration aerosol for particle counters. It does not replace coarse-test dust standards when a coarse-dust challenge is required.
