Water absorption is used to determine the amount of water absorbed under specified conditions.
Validating the specifications, value and safety of your raw materials, products and assets. 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. 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. Historical Version s – view previous versions of standard. 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.
Immediately upon cooling the specimens are weighed. 5d70
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Link to Active This link will always route to the current Active version of the standard.
Sstm 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. Water absorption is expressed as increase in weight percent.

Standards can be obtained from appropriate standard authorities. Inspection Validating the specifications, value and safety of your raw materials, products and assets. This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product.
Formally confirming that your products and services meet all trusted external and internal standards. Assurance Testing Inspection Certification. Time to saturation is strongly dependent on specimen thickness. Auditing Consulting Sourcing Training. Factors affecting water absorption include: The data sheds light on the performance of the materials in water or humid environments.

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. Two inch diameter disks, 0. Need help or have a question? Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
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.
The values stated in parentheses are for information only. Certification Formally confirming that your products and services meet all trusted external and internal standards.
With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface. 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.
