GB/T 29024.4-2017 "Determination of particle size distribution - Single particle light interaction methods - Part 4: Light scattering airborne particle counter for clean spaces" specifies the requirements for particle size analysis using light scattering airborne particle counters in cleanrooms. It covers instrument calibration, sampling methods, measurement conditions, data processing, and result presentation, and defines specific indicators such as particle counting accuracy, particle size calibration, and sampling flow control. This standard is applicable to measuring the particle size and number concentration of airborne particles in cleanrooms, providing a technical basis for detecting particle contamination in clean environments.
