SS-EN-ISO-8130-10 › Coating powders - Part 10: Determination of deposition efficiency (ISO 8130-10:1998)
The following bibliographic material is provided to assist you with your purchasing decision:
This part of ISO 8130 is one of a series of standards dealing with the sampling and testing of paints,varnishes and related products.It specifies a method for determining the percentage by mass of a sprayed coating powder which is actuallydeposited on a standard test target when powder is sprayed at the target from a spray gun under standardconditions.The method is applicable to powders applied by corona charging or tribo charging.The method may be used to compare the deposition efficiency of different powders with the same gun or ofdifferent guns with the same powder.This method should only be used for comparison when powders or guns are evaluated consecutively, as theinfluence of the environment and the equipment can vary significantly with time and location.The results are dependent on the following properties 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.
