Standards can be obtained from appropriate standard authorities. Link to Active This link will always route to the current Active version of the standard. 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 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.

This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product.
