适用范围：This part of ISO 8130 is one of a series of standardsdealing with the sampling and testing of paints,varnishes and related products.It specifies a method for determining the percentageby mass of a sprayed coating powder which isactually deposited on a standard test target whenpowder is sprayed at the target from a spray gununder standard conditions.The method is applicable to powders applied bycorona charging or tribo charging.The method may be used to compare the depositionefficiency of different powders with the same gun orof different guns with the same powder.This method should only be used for comparisonwhen powders or guns are evaluated consecutively,as the influence of the environment and theequipment can vary significantly with time andlocation.The results are dependent on the followingproperties of the powder:a) chemical composition;b) density;c) particle size distribution;d) particle shape;e) flow properties of its mixture in air;f) moisture content;and also on the test conditions, including:g) spray pattern produced by the gun;h) gun air pressure;i) gun voltage;j) gun polarity;k) air humidity.
