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.

ASTM D570 – 98(2010)e1

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. Specimens are removed, patted dry with a lint free cloth, and weighed.

For materials of widely varying density, relation between water-absorption values on a volume as well as a weight basis may need atm be considered. Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces. 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. Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely dd570 materials and to similarly shaped specimens: For example, Axtm 1 shows the time to approximate time saturation for various thickness of nylon Factors affecting water absorption include: Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
