This specification describes the General Motors approval process for decorative chrome plating. The plater must obtain an approval for each substrate material, chemical source, finish, and facility combination.

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose/Material Description.

The entire Class A part surface is to meet all requirements.

Symbols.

Not applicable.

Applicability.

Chrome plated exterior and interior applications.

Remarks.

Finish suppliers (platers) should be approved before Tier 1 sourcing. The Tier 1 should select approved platers from their respective regions. If a new plater is to be developed, GM Materials Engineering, Supplier Quality (SQ), and Purchasing must agree to the proposed plater before sourcing is finalized.

If a new plater is to be developed, the Tier 1 is responsible for:

a. Determining the plater’s ability to meet all pre-production part submission dates utilizing production processes.

b. Consulting with GM Materials Engineering.

c. Ensuring that the plater is approved before Integration Vehicle Engineering Release. The Tier 1 should identify an approved backup plating source in these cases.

Once a plater has successfully completed the approval process, their approval record (trim transmittal) will be available on the GM Supply Power web site. The trim transmittal will support the Tier 1 - GM Production Part Approval Process (PPAP). One approval may be applicable for future parts with the same combination. Any substrate, solution chemistry, supplier, process, or facility change is subject to re-qualification (including a new trim transmittal).

Approvals are contingent on satisfactory quality performance. Poor quality performance may lead to an additional audit and quality improvement plan, at the discretion of the GM Materials Engineer and Supplier Quality Global Process Lead. If the plater is non-compliant with the subsequent action items, removal from the approved list may occur.

Note: An approval is based on single part geometry. Subsequent parts must be tested to meet GM PPAP requirements (GM Materials Engineering reserves the right to require an additional approval if part complexity warrants).
