  • ASTM D6869 - 03(2011) standard test method for coulometric and volumetric determination of moisture in plastics using the karl fischer reaction (the reaction of iodine with water)

    Moisture will affect the processability of some plastics. High moisture content causes surface imperfections (that is, splay or bubbling) or degradation by hydrolysis. Low moisture (with high temperature) causes polymerization. The physical properties of some plastics are affected by the moisture content. 1. Scope 1.1 This method uses the reaction of Iodine (I2) ...
