Détails
This standard describes the surface appearance and quality requirements for evaluating the appearance of production-level, chrome-plated, interior and exterior metal and plastic parts.
Criteria is established for the determination of allowable appearance criteria based upon the significance of the chrome-plated surface as outlined in standard specifications for electrodeposited coatings for plastic and metal parts (ASTM B604 and ASTM B456, respectively). This specification defines appearance definitions for chrome-plated parts covered under GMW14668, GMW14672, GMW15613, and any other decorative chrome-plated performance specifications. ASTM B456 and ASTM B604 define significant surfaces as those surfaces normally visible (directly or by reflection) that are essential to the appearance and/or serviceability of the component when assembled in normal position, or that can be the source of corrosion products that have the potential to deface visible and significant surfaces on the assembled component.
If, after field exposure or accelerated corrosion testing, product corrosion is experienced but not previously considered for degree of visibility, surfaces are permitted to be redefined on the drawing. Contact GM Materials Engineering or the part Subsystem Management Team (SMT) if assistance is needed in defining part surfaces.
