DIN EN ISO 15512:2016-06

This International Standard 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. The methods are suitable for the determination of water content as low as 0,01 % or better. Water content is an important parameter for processing materials and has to remain below the level specified in the appropriate material standard. Four alternative methods are specified in this International Standard: Method A - Extraction with anhydrous methanol, Method B1 - Water vaporization using a heating tube oven, Method B2 - Water vaporization using a heated sample vial and Method C - Manometric method.
