The ISO 8130-10:2021 standard specifies a method for determining the deposition efficiency of powder coatings under known spray gun and environment conditions. The standard is suitable for evaluating the mass fraction of Coating powder on target articles during lame plating. The standard is suitable for comparing the deposition effects of different spray guns or powders, helping to optimize lame plating processes and improve production efficiency. The new version of the standard updates test reporting requirements and simplifies the handling of accuracy data to better support efficiency evaluation in practical applications.
