3、M1P96-B3 (CHROME FLASH), LEVEL 3 CORROSION 1. SCOPE These specifications define performance requirements for electrodeposited chromium flash on polished stainless steel surfaces. 2. APPLICATION These specifications were released originally for a coating where a bright or low gloss decorative and/or
4、 protective metallic finish is required on stainless steel surfaces such as exhaust outlet tips or interior and exterior moldings. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Productio
5、n Materials (WSS-M99P1111-A). 3.2 APPEARANCE All parts shall have the finish bright or low gloss as specified on the engineering drawing. The plated parts shall be free from surface imperfections. Bright or low gloss parts shall match the approved Styling master sample for appearance. 3.2.1 Low Glos
6、s Finishes These finishes must be applied to the stainless steel, before chrome flashing. 3.2.2 Buffing Chromium Plating Because of the potential adverse effect on corrosion resistance, buffing of final chromium plating on parts is not permitted.

13、0040, Reference 1. 3.7 SURFACE FINISH When a low gloss finish is specified for glare reduction surfaces to meet FMVSS requirements, it shall be designated on the Engineering Drawing. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requir
14、ements of these specifications. 4.1 SIGNIFICANT SURFACES Unless otherwise specified on the engineering 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 reflection.
