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. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
Validating the specifications, value and safety of your raw materials, products and assets. 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.
Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Factors affecting water absorption include: Standards can be obtained from appropriate standard authorities.
This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be s570 different through each edge and surface.
Water Absorption ASTM D570
The data sheds light on the performance of the materials in water or humid environments. Water absorption is expressed as increase in weight percent. The values stated in parentheses are for information only. Immediately upon cooling the specimens are weighed.

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. Formally confirming that your products and services meet all trusted external and internal standards. Time to saturation is strongly dependent on specimen thickness. Consequently, attempts to correlate water absorption with the dd570 area must generally be limited to closely related materials and to similarly shaped specimens: Auditing Consulting Sourcing Training.
