Die Annotation des Normtextes ASTM D4101-24 :

This specification covers polypropylene materials, suitable for injection molding and extrusion, that include unreinforced polypropylene with natural color only, unfilled and unreinforced polypropylene, calcium carbonate filled polypropylene, glass reinforced polypropylene, polypropylene copolymers, and talc filled polypropylene. Polymers consist of homopolymer, copolymers, and elastomer compounded with or without the addition of impact modifiers (ethylene-propylene rubber, polyisobutylene rubber, and butyl rubber), colorants, stabilizers, lubricants, or reinforcements. Tests shall be conducted on each of the specimens to determine the required physical and mechanical properties of the materials. The specimens for the various materials shall conform to the following requirements: nominal flow rate; test specimen dimensions; tensile stress at yield; flexural modulus; Izod impact resistance; deflection temperature; and multiaxial impact ductile-brittle transition temperature.
