3、f mechanically or chemically deposited electrical conductor coat and electrodeposited copper, nickel, and chromium for the decoration and protection of acrylonitrile butadiene styrene (ABS), polycarbonate/acrylonitrile butadiene styrene (PC/ABS) or filled nylon (PA) parts. 2. APPLICATION These speci
4、fications were released originally where a bright or low gloss decorative and/or protective finish is required for interior or exterior parts. Unless otherwise specified on the engineering drawing, all parts shall be finished with a final coating of chromium. Two levels of performance are defined as
5、 follows: WSS-M1P83-C1 Interior part applications WSS-M1P83-C2 Exterior part applications For coating over chrome applications, refer to WSS-M2P191-A1 for interior applications and WSS-M2P191-A2 for exterior applications.

No one requirement, exclusive of others, is capable of insuring satisfactory performance. Any deviations to the req
7、uirements of these specifications may be subject to additional performance requirements. All part testing requirements apply to those areas of the part identified as a significant surface (per paragraph 4.3) unless otherwise specified on the engineering drawing. 3.1 STANDARD REQUIREMENTS FOR PRODUCT
8、ION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 APPEARANCE The plated parts shall be free from surface imperfections.

Appearance Evaluation: No evidence of cracks or blisters, per paragraph 3.7.2. 3.8.2 Environmental Cycling for C2 only (FLTM BQ 104-07, Procedure 1) All parts shall be complete including all components packaged in the assembly a
15、nd fastened onto actual or representative production support foundations that include not only all attaching points but also any boundary conditions that may restrict movement, unless otherwise specified by the affected Materials Engineering Activity. The retention methods, attachments and supportin
16、g moldings shall be the same as proposed for production. The cycled part shall show no evidence of warpage, deformation, cracks, delamination or other failures to an extent that would affect its use in the ultimate assembly. The cycled part shall show no changes in appearance when compared with the
17、original untested part. Gaps, margins and surface waviness must be within original vehicle design tolerances after returning to ambient temperature. After Environmental testing is complete, perform 3.3.1 and 3.3.2. No defects per paragraph 3.7.2. 4. GENERAL INFORMATION The information given below is

19、PC/ABS WSB-M4D813-A . Plating Grade Mineral Filled Nylon WSS-M4D429-C1 4.2 MOLDED PARTS Plastic parts intended for plating by this specification must be molded in keeping within the best commercial practice to achieve stress-free parts and ensure good plateability. Molded-in stresses can result in p
20、art failure by loss of plating adhesion (blistering) and/or cracking of the plastic and/or plating when subjected to service temperature extremes. Parts must be stress relieved prior to plating and subsequent to plating as required. 4.3 SIGNIFICANT SURFACES Unless otherwise specified on the engineer
21、ing drawing, significant surfaces are defined as those surfaces of the finished part that: - Are directly visible and/or visible by reflection when the finished part is assembled in car position. - Can be the source of corrosion products directly visible or visible by reflection. 4.4 DUCTILITY (ASTM
22、 B 490) Although this is considered a portion of the process control and not a requirement of part performance, the ductility percentage of Semi-bright Nickel and Bright Nickel on foils plated in the individual nickel baths should be rated, reported, and included in the Control Plan.
