With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface. The data sheds light on the performance of the materials in water or humid environments. Send us a request Wilton UK: Immediately upon cooling the specimens are weighed.
This second function is particularly applicable to sheet, rod, and tube arms when asrm test is made on the finished product. Factors affecting water absorption include: Need help or have a question? The aastm stated in parentheses are for information only.
Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely related materials and to similarly shaped specimens: Specimens are removed, patted dry with a lint free cloth, and weighed.
Auditing Consulting Sourcing Training. Time to saturation is strongly dependent on specimen thickness. Validating the specifications, value and safety of your raw materials, products zstm assets.

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. For materials of widely varying density, relation axtm 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. Two inch diameter disks, 0. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon 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 d70 and tube form and in sheets 0.
For the water absorption test, the specimens are r570 in an oven for a specified time and temperature and then placed in a desiccator to cool.
Water absorption is used to determine the amount of water absorbed under specified conditions. Link to Active This link will always route to the current Active version of the standard.
