ActiveAerosol particle number concentration—Calibration of condensation particle counters
气溶胶颗粒数量浓度 凝结核颗粒计数器的校准
Application Summary AI generated
This standard specifies the calibration method for condensation particle counters used to measure aerosol particle number concentration. It is applied in environmental monitoring, cleanroom certification, and industrial hygiene testing where accurate counting of ultrafine particles (typically 1-100 nm) is required. The standard ensures traceability and consistency in particle concentration measurements across laboratories and field instruments.
