本文件规定了测定涂层材料导电性和电阻的方法。导电性通常用于测量水性涂料和清漆，包括电沉积涂层材料，而电阻通常用于测量溶剂性涂料和清漆。如果需要，涂层材料的电阻率可根据上述任一测量值进行计算。该方法适用于电导率小于5μS/cm，对应于电阻率大于200 kΩ？cm的产品。 涂层材料的导电性影响其在电场作用下的加工性能。这对于静电处理的电沉积涂料和涂层材料尤为重要。

This document specifies a method for determining the electrical conductivity and the electrical resistance of coating materials. The conductivity is usually measured for water-borne paints and varnishes, including electrodeposition coating materials, and the resistance is usually measured for solvent-borne paints and varnishes. If required, the resistivity of the coating material is calculated from either of these measurements. The method is applicable to products having a conductivity less than 5 μS/cm, corresponding to a resistivity greater than 200 kΩ？cm. The conductivity of coating materials influences their processibility in the presence of an electric field. This is particularly important for electrodeposition paints and coating materials which are processed electrostatically.
