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 0. The data sheds light on the performance of the materials in water or humid environments. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing 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 humidity , shape of the part, and inherent properties of the plastic. The values stated in parentheses are for information only. If the document is revised or amended, you will be notified by email. This standard is also available to be included in Standards Subscriptions.

Two inch diameter disks, 0. Global Reach Intertek is the industry leader with over 42, people in 1, astm d570-98 in over countries. For materials of widely varying density, asstm between water-absorption values on a volume as well as a weight basis may need to be considered. Specimens are removed, patted dry with a lint free cloth, and weighed.
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 0.

ASTM D – 98 Standard Test Method for Water Absorption of Plastics
With nonhomogeneous materials, xstm as laminated forms, the astm d570-98 of water absorption may be widely different through each edge and surface.
Validating the specifications, value and safety of your raw materials, products and assets. Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Subscription pricing is determined by: Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely related materials and to similarly shaped specimens: Time to saturation is strongly dependent on specimen thickness.
Standards can be obtained from appropriate standard authorities. Water absorption is expressed as increase in weight percent. Link to Active This link will always route to the current Active astm d570-98 of the standard.
