本文件规定了一种测定沾污材料的方法，例如，从以前的工艺、不分散的油漆颗粒和电沉积涂层材料中的其他异物中获得的沾污材料。 它适用于汽车工业和其他一般工业应用的电沉积涂层，例如冷却装置、消费品、散热器、航空航天和农业。 在实践中，增加的筛余物可能有不同的原因，例如金属颗粒（与待涂覆的物体一起引入）或凝块。

This document specifies a method for the determination of soiling material, e.g. from previous processes, non-dispersed paint particles and other foreign material in the electro-deposition coating material. It is applicable to electro-deposition coatings for automotive industries and other general industrial applications, e.g. chiller units, consumer products, radiators, aerospace, agriculture. In practice, increased sieve residue can have different causes, such as metal particles, which are introduced together with the object to be coated, or clots.
