ASTM D – 98 Standard Test Method for Water Absorption of Plastics
Time to saturation is strongly dependent on specimen thickness. Formally confirming that your products and services meet all trusted external and internal standards. Need help or have awtm question? Water absorption is expressed as increase in weight percent.
ASTM D570 – 98(2010)e1

Specimens are removed, patted dry with a lint free cloth, aetm weighed. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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. Validating the specifications, value and safety of your raw materials, products and assets. The values stated in parentheses are for information only. Immediately upon cooling the specimens are weighed.
With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.
Factors affecting water absorption include: Certification Formally confirming that your products and services meet all trusted external and internal standards. Assurance Testing Inspection Certification.
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. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Water absorption is used to determine the amount of water absorbed under specified conditions. 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 ashm plastics in rod and tube form and in asttm 0.
Historical Version s – view previous versions of standard. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. 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.

Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces. Standards can be obtained from appropriate standard authorities.
