6、the requirements as stated in thisspecification are met, and (2) the material has not beenmodified in any way to alter its conformance to food contactregulations or similar requirements. The proportions ofrecycled, reconstituted, and reground material used, as well asthe nature and the amount of any

7、 contaminant, cannot bepractically covered in this specification. It is the responsibilityof the supplier and the buyer of recycled, reconstituted, andreground materials to ensure compliance. (See Guide D7209.)1.3 The values stated in SI units are to be regarded as thestandard.NOTE 1The properties i

Polypropylene random copoly-mers containing more than one additional monomer are oftencalled “terpolymers.”4. Classification4.1 Unreinforced polypropylene materials are classified intogroups according to basic c

44、omposition. These groups aresubdivided into classes and grades, as shown in Table PP.NOTE 3An example of this classification system is as follows. Thedesignation PP0113 would indicate: PP = polypropylene, as found inTerminology D1600, 01 (group) = homopolymer, 1 (class) = generalpurpose, and 3 (grad
