| Resumen: | This document specifies methods for the determination of the water content of plastics in the form of powder, granules, and finished articles. These methods do not test for water absorption (kinetics and equilibrium) of plastics as measured by ISO 62. Water content is an important parameter for processing materials and has to remain below the level specified in the appropriate material standard. Six alternative methods are specified in this document: Method A - Extraction with anhydrous methanol, Method B1 - Water vaporization using a heating tube oven, Method B2 - Water vaporization using a heated sample vial, Method C - Manometric method, Method D - Water detection by using a diphosphorus pentoxide cell and Method E - Determination of water content by calcium hydride method. |
