Air cleaning equipment - Test aerosols for filter evaluation - Salt aerosols reproducing the accumulation mode in typical urban atmospheres prEN ISO 26786

Scope

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.
