With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface. 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.
ASTM D – 98()e1 – Standard Test Method for Water Absorption of Plastics
Two inch diameter disks, 0. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Assurance Testing Inspection Certification.

Send us a request Wilton UK: The data sheds light on the performance of the materials in water or humid environments.
Standards can be obtained from appropriate standard authorities. Factors affecting water absorption include: Validating the specifications, value and safety of your raw materials, products and assets. 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.
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. Immediately upon cooling the specimens are weighed.

For example, Table 1 shows the time to approximate time saturation for various thickness dd570 nylon 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. Evaluating how your 89 and services meet and exceed quality, safety, sustainability and performance standards.
This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product. This test method is intended to apply to the testing of all types of plastics, including cast, hot-molded, and cold-molded asm products, and both homogeneous and laminated plastics in rod and tube form and in sheets 0.
Water Absorption ASTM D
Time to saturation is strongly dependent on specimen thickness. Water absorption is expressed as increase in weight percent. Specimens are removed, patted dry with a lint free cloth, and weighed. Need help or have a question?
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The values stated in parentheses are for information only. For materials of widely varying density, relation between water-absorption values on a volume as dd570 as a weight basis may need to be considered.
