44、Classification4.1 Unreinforced polypropylene materials are classified into groups according to basic composition. These groups aresubdivided into classes and grades, as shown in Table PP.NOTE 3An example of this classification system is as follows. The designation PP0113 would indicate: PP = polypro

45、pylene, as found in TerminologyD1600, 01 (group) = homopolymer, 1 (class) = general purpose, and 3 (grade) = with requirements given in Table PP.4.1.1 To facilitate the incorporation of future or special materials not covered by Table PP, the “other/unspecified” category forgroup (00), class (0), an
