scope:

This document establishes a centralized set of electrical and mechanical validation methods and tests for GM Loudspeaker Components and Subsystems. Performance requirements shall be established in accordance to the Validation Test Plan, SSTS, and CTS for each appropriate level.

The Analysis procedures are used to aid in designing reliability into the product. The Development / Evaluation tasks are to be performed on first samples to provide a quick assessment of the product's capability.

Note: High risk design validation tests shall also be run during the development / evaluation phase.

The Design Validation (DV) section of this standard describes environmental, durability and capability tests for loudspeakers for passenger vehicles and light duty trucks.

The Reliability section of this standard describes analytical and test methods that would demonstrate reliable operation of the E/E equipment during their expected life in the vehicle.

The design validation tasks and reliability tests are to be executed on prototype parts. Typical test sequences are in Appendix A.

For Product Validation (PV) testing has been reduced with the requirement of part compliance to DV testing and no significant changes to the part design. Those changes deemed significant by the GM Engineering will require complete DV and PV testing.

The product validation tasks are to be run on pilot or production parts.

The supplier is required to support and participate in subsystem or vehicle level A/D/V tasks as specified in the Statement of Requirements (SOR), CTS, or by GM Engineering.
