Standards can be obtained from appropriate standard authorities. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.
Water absorption is expressed wstm increase in weight percent. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability d57 regulatory limitations prior to use.
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.

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. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
For asttm of widely varying density, relation between water-absorption values on a volume as well as a weight basis may need to be considered. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Immediately upon cooling the specimens are weighed.
Global Reach Intertek is the industry leader with over 42, zstm in 1, locations in over countries. The data sheds light on the performance of the materials in water or humid environments. Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.

Through our network of d57 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. 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.
Specimens are removed, patted dry with a lint free cloth, and weighed.
ASTM D – 98()e1 – Standard Test Method for Water Absorption of Plastics
Water absorption is used to determine the amount of water absorbed under specified conditions. This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. 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.
