Annotation of standard text ASTM D5857-17(2024) :
This specification covers polypropylene materials suitable for injection molding and extrusion. Polymers consist of polypropylene homopolymers, polypropylene copolymers, and polypropylene-elastomer compounds produced with or without the addition of impact modifiers (ethylene-propylene rubber, polyisobutylene rubber, and butyl rubber, and so forth), colorants, stabilizers, lubricants, fillers, or reinforcements. Unreinforced polypropylene materials are classified into groups in accordance with basic composition. These groups are subdivided into classes and grades. The plastic composition shall be uniform and shall conform to the requirements specified. Tests shall be performed to determine the properties of the material in accordance with the following test methods: flow rate; tensile strength; flexural modulus; Charpy impact resistance; falling mass impact resistance; temperature of deflection under load; and multiaxial impact ductile-brittle transition temperature.
