Any change to the component o

14、r material, e.g., design, function, properties, manufacturing process and/or location of manufacture requires a new release of the product. It is the sole responsibility of the supplier to provide the customer, unsolicited, with documentation of any change or modification to the product/process, and

15、 to apply for a new release. If not otherwise agreed to, the entire verification test shall be repeated and documented by the supplier prior to start of delivery of the modified or changed product. In some cases, a shorter test can be agreed to between the responsible GM department and the supplier.

16、 3.7.1 Test Results. 3.7.1.1 Interpretation of Results. GM Powertrain Materials Engineering will review the test results and reserves the right to determine whether a product meets this standard. Additional testing may be required based on the type of product or the test results. A test report forma
