ISO 21501 3 is a safety standard on single particle light interaction methods. ISO 21501 3 describes a calibration and verification method for a light extinction liquid borne particle counter (LELPC), which is used to measure the size and particle number concentration of particles suspended in the liquid. The light scattering method described in ISO 21501 3 is based on single
