What 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 cm–3 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 performance characteristics and the minimum requirements of the instruments to be used.
