The American Society for Testing and Materials (ASTM) is an organization that defines and sets standards to ensure good quality and workmanship. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific gravity means more material per pound or varied part weight. There are two basic test procedures- Method A and Method B. The more common being Method A, can be used with sheet, rod, tube and molded articles.
