More D Requirements necessary to identify particular characteristics important to specialized applications may be described by using the given classification system. The use of recycled plastics is allowed in the specification. The materials shall be subject to tests to determine tensile strength at break, tensile modulus, dimensional stability, lengthwise camber and widthwise bow, squareness, flexural modulus, and Izod impact. This abstract is a brief summary of the referenced standard.
