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.
adtm Water absorption is used to determine the amount of water absorbed under specified conditions. Send us a request Need help or have a question? 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. Certification Formally confirming that your products and services meet all trusted external and internal standards.
ASTM D – 98 Standard Test Method for Water Absorption of Plastics
Two inch diameter disks, 0. 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. Standards can be obtained from appropriate standard authorities. The data sheds light on the performance of the materials in water or humid environments. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Send us a request Wilton UK: Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
Assurance Testing Inspection Certification. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance ast. 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.

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. Inspection Validating the specifications, value awtm safety of your raw materials, products and assets.
With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.
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.
Factors affecting water absorption include: Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. Water absorption is expressed as increase in weight percent. D750 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. Link to Active This link will always route to the current Active version of the standard. Time to saturation is strongly dependent on specimen thickness.
Enabling you to identify and mitigate the intrinsic ashm 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. 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.
