Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The effect upon these properties of change in moisture content due to water absorption depends largely on the type of exposure by immersion in water or by exposure to high humidityshape of the part, and inherent properties of the plastic.

Assurance Testing Inspection Certification. Specimens are removed, patted dry with a lint free cloth, and weighed. For the water absorption test, the specimens are astn in an oven for d507 specified time and temperature and then placed in a desiccator to cool.

Water absorption is expressed as increase in weight percent. Send us a request Need help or have a question? Validating the specifications, value and safety of your raw materials, products and assets.

This test method is intended to apply to the testing of all types of plastics, including cast, hot-molded, and cold-molded resinous products, and both homogeneous and laminated plastics in rod and tube form and in sheets sstm. For materials of widely varying density, relation between water-absorption values on a volume as well as a weight basis may need to be considered. Send us a request Wilton UK: Water absorption is used to determine the amount of water absorbed under specified conditions.

With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The data sheds light on the performance of the materials in water or humid environments. Whether your business is local or global, we asrm ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

Factors affecting water absorption include: It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
