1.1 This test method is the standard procedure for determining the weight of water absorbed by a molded or machine-prepared test specimen from sheet, rod, or tube as a result of immersion in water. for a specified time and temperature. A variant is included which indicates the method to be adopted when it is considered appropriate to take into account the presence of soluble matter in water. 1.2 The method applies to all types of plastics, including cast materials, molding, compression and injection materials, extrusion compounds, both flexible and rigid, in sheets, rods or tubes.
