Ambient air. Determination of the particle number concentration of atmospheric aerosol Ingestion-build-258901 BS 8489-7 outlines specifications forWhat is PD CEN TS 16976 Ambient air about? PD CEN TS 16976 describes a standard method for determining the particle number concentration in ambient air in a range up to about 107 cm3 for averaging times equal to or larger than 1 min. PD CEN TS 16976 is based on a Condensation Particle Counter (CPC) operated in the counting mode and an appropriate dilution system for concentrations exceeding the counting mode range. PD CEN TS 16976 defines the
