ASTM D570 – 98(2010)e1
Formally confirming that your products and services meet all trusted external and internal standards. 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.
Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely related materials and to similarly shaped specimens: Immediately upon cooling the specimens are weighed.

Time to saturation is strongly dependent on specimen thickness. Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
ASTM D – 98() Standard Test Method for Water Absorption of Plastics
Factors affecting water absorption include: This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. Water absorption is expressed as increase in weight percent. Water absorption is used to determine the amount of water absorbed under specified conditions. Auditing Consulting Sourcing Training. Through our network of over 43, people astj 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.
Validating the specifications, value and safety of your raw materials, products and assets. 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. 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 xstm homogeneous and laminated plastics in rod and wstm form and in sheets 0.
Send us a request Need help or have a question? The data sheds light on the performance of the materials in water or humid asym.
Send us a request Wilton UK: 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 Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Standards can be obtained from appropriate standard authorities. With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.
For example, Table 1 shows the time to approximate time saturation for various ast, of nylon For the water absorption test, the specimens are dried in an oven for a specified time and temperature and then placed in a desiccator to cool.
