3、cimen preparation procedures and test method based on ISO standards.This specification is not intended for the determination of the suitability of performance of materialsin the final application. Selection of these materials is to be made by personnel with expertise in theplastics field in which th
4、e environment, inherent properties of the materials, performance of the parts,part design, manufacturing process, and economics are considered.1. Scope*1.1 This specification covers polypropylene materials suit-able for injection molding and extrusion. Polymers consist ofpolypropylene homopolymers,
5、polypropylene copolymers, andpolypropylene-elastomer compounds produced with or withoutthe addition of impact modifiers (ethylene-propylene rubber,polyisobutylene rubber, and butyl rubber, and so forth), colo-rants, stabilizers, lubricants, fillers, or reinforcements.1.2 This specification allows fo
6、r the use of those polypro-pylene materials that can be recycled, reconstituted, andreground, provided that the following conditions are met:1.2.1 The requirements as stated in this specification andother ISO guidelines pertaining to these types of materials aremet, and1.2.2 The material has not bee
7、n modified in any way to alterits conformance to food contact regulations or similar require-ments.1.3 The proportions of recycled, reconstituted, and regrindmaterial used, as well as the nature and the amount of anycontaminant, cannot be practically covered in this specifica-tion. It is the respons
8、ibility of the supplier and buyer ofrecycled, reconstituted, and regrind materials to ensure com-pliance.1.4 The properties included in this classification system arethose required to identify the compositions covered. There maybe other requirements necessary to identify particular charac-teristics
9、important to specialized applications. These may bespecified by using the suffixes as given in Section 5 and thosein Classification System D 4000.1.5 This classification system and specification are intendedto provide a means of calling out polypropylene materials usedin the fabrication of end items
10、 or parts. It is not intended for theselection of materials. Material selection should be made bythose having expertise in the plastic field after careful consid-eration of the design and the performance required of the part,the environment to which it will be exposed, the fabricationprocess to be e
11、mployed, the costs involved, and the inherentproperties of the material other than those covered by thisspecification.1.6 The values stated in SI units are to be regarded as thestandard.1.7 The following precautionary caveat pertains only to thetest methods portion, Section 13, of this specification
12、: Thisspecification does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this specification to establish appropriate safetyand health practices and determine the applicability of regu-latory limitations prior to use.NOTE 1This
13、 specification is similar to both ISO 1873-1 andISO 1873-2, but to different degrees. This specification resemblesISO 1873-1 in title only. The content is significantly different. Thisspecification and ISO 1873-2 differ in approach or detail; data obtainedusing either are technically equivalent.2. R
