This Specification is issued for the first time. Calibration Specification for Aerosol Photometers1 ScopeThis Specification applies to the calibration of light scattering principle aerosol photometers with a measurement range of (0.01~100) μg/L. The aerosol photometers with other measuring ranges can be calibrated with reference to this Specification.2 TermsPAO-4 aerosol Aerosol refers to a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. It is also called as gas dispersion system. Its dispersion phase is solid, liquid or solid-liquid mixture. PAO-4 aerosol in this Specification refers to polydisperse aerosol, which takes poly-alpha-olefin oil (PAO) with a kinematic viscosity of 4m2/s as the generating medium and is generated by the fog mixing device of the aerosol photometer.3 OverviewAerosol photometer (hereinafter referred to as the instrument) is an instrument used to measure the leakage rate of high-efficiency filters and the leakage rate of high- efficiency filtration systems installed with high-efficiency filters.4 Metrology characteristics4.1 Sampling flow indication error. no more than ±5%. 4.2 Sampling flow repeatability. not more than 2%. 4.3 Sampling flow stability. sampling flow is not more than 5% within 1h.5 Calibration conditions5.1 Environmental conditions 5.1.1 Temperature.
