Immediately upon cooling the specimens are weighed. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Formally confirming that your products and services meet all trusted external and internal standards. Send us a request Need help or have a question? 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.
The data sheds light on the performance of the materials in water or humid environments. 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. 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.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Inspection Validating qstm 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 ashm finished product.
Time to saturation is strongly dependent on specimen thickness. Water absorption is expressed as increase in weight percent.
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.
Auditing Consulting Sourcing Training. Specimens are removed, patted dry with a lint free cloth, and weighed. 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. 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
Factors affecting water absorption include: Validating the specifications, value and safety of your raw materials, products and assets. Send us a request Wilton UK: Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface. The values stated in parentheses are for information only. Assurance Testing Inspection Certification.
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.
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. Link to Active This link will always route to the current Active version of the standard.
Need help or have a question? Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely related materials and to similarly shaped specimens: Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Water absorption is used to determine the amount of water absorbed under specified conditions.
