2、G COMPOUND, IDENTIFICATION OF WRS-M99P42-A1 RECYCLED CONTENT 1. SCOPE The material defined by this specification is a thermoplastic, thermoset, elastomeric compound or insulation material (felt) based on recycled grades of post industrial (PIR) or post consumer (PCR) origin. 2. APPLICATION This spec
3、ification provides direction to the suppliers of components with recycled content. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.2 MATERIAL IDENT
4、IFICATION RECYCLED CONTENT: The portion of a materials or products weight that is composed of materials that have been recovered from or otherwise diverted from the scrap stream, either from the manufacturing process (PIR) or after consumer use (PCR). Recycled content can be either PIR or PCR, but n
5、ot home scrap. 3.2.1 Post Industrial Recycled content (PIR) Scrap which is a by-product of the manufacturing process and is re-used in the manufacture of a part. Several exclusions apply, e.g., home scrap. Each case should be evaluated by Material Engineering for final approval. 3.2.2 Post Consumer
6、Recycled content (PCR) Scrap generated by consumers which has been re-used in the manufacturing of a new part. Examples are used carbonated drink bottles which are reused to make grill opening panels, or used bumpers whose material is re-incorporated in different % in the mix of materials used for t
7、he production of new bumpers. 3.2.3 Repolymerised Recycled content (PIR/PCR) Repolymerised materials originate from at least one polymeric material which is depolymerised in a chemical process to its monomers/oligomers. The monomers/oligomers are then repolymerised on their own or with the addition
8、of different monomers (these could be either virgin or recycled). ENGINEERING MATERIAL SPECIFICATION WRS-M99P42-A1 Copyright 2013, Ford Global Technologies, LLC Page 2 of 2 Example: PCR or PIR Polyethyleneterephthalate (PET) repolymerised with Butyldiol (BDO) to Polybutyleneterephthalate (PBT). NOTE
9、: NOT TO BE CLASSED AS RECYCLED CONTENT: Home Scrap: Material commonly reused by the industry within the original manufacturing process (standard practice). Examples include materials which are regranulated and re-moulded within a facility. Home scrap is not considered recycled content. Regranulated
10、 (regrind): should not be considered recycled content if it is home scrap (see definition above). Off spec materials: these are virgin materials that did not meet the specification they were produced to; nevertheless they would never be disposed of in landfill and are generally sold to be recompound
11、ed. 3.3 RESTRICTED SUBSTANCES REPORTING Material suppliers and part producers shall report on the materials content of their products using the International Material Data System (IMDS). See the Ford Restricted Substance Management Standard, WSS-M99P9999-A1. IMDS Reporting of recycled content: Only
12、the weight of the recycled content within the component or assembly should be reported. Do not report the component or assembly weight as recycled content. This weight is reported and totaled separately. For PCR only, suppliers do not have to report “Declarable“ substances unless otherwise specified
13、, although suppliers must report any substances that are listed in this Standard as “Prohibited“ or “Prohibited above threshold“. 3.4 MATERIAL IDENTIFICATION FOR RECYCLING PURPOSES All polymeric (plastic, elastomeric or synthetic fiber) parts shall be marked for recycling per Ford Motor Company Engi
14、neering CAD and Drafting Standard E-4. NOTE: Use latest publication of ISO 18064: Thermoplastics elastomers - Nomenclature and abbreviated terms. 4.
