With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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. Auditing Consulting Sourcing Training.
X570 inch diameter disks, 0. Standards can be obtained from appropriate standard authorities. The data sheds light on the performance of the materials in water or humid environments.
Factors affecting water absorption include: Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Need help or have a question? Validating the specifications, value and safety of your raw materials, products and assets.
Specimens are removed, patted dry with a lint free cloth, and weighed. Certification Formally confirming that your products and services meet all trusted external and internal r570. Water absorption is used to determine the amount of water absorbed under specified conditions.

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. This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. Immediately upon cooling the specimens are weighed. Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely related materials and to similarly shaped specimens: The values stated in parentheses are for information only.
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
Water absorption is expressed as increase in weight percent. Historical Version s – view previous versions of standard.
For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Send us a request Wilton UK: 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. Send us a request Need help or have a question?
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. Formally confirming that your products and services meet all trusted external and internal ast. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Time to saturation is strongly dependent on specimen thickness.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
