9、 any changes, e.g., properties, manufacturing process, location of manufacture, etc. If not otherwise agreed, all testing and documentation normally required for initial release must be completed. It is the responsibility of the supplier to inform the customer in a timely manner, without solicitatio
10、n, and to include documentation of all modifications of materials and/or processes and to apply for a new release. If not otherwise agreed, all release tests shall be repeated and documented by the supplier prior to commencement of delivery of non-conforming bulk supplies. In individual cases, a sho
11、rter test can be agreed to between the responsible Engineering department and the supplier. 5.4 Initial Source Approval. No shipments shall be made by any supplier until representative initial production samples have been approved by the appropriate Materials Engineering department(s) as meeting the
12、 requirements of this specification. 5.5 Material Safety Data Sheets/Safety Data Sheets (MSDS/SDS). For new product submissions, or when a change in chemical composition of an existing product has occurred, a complete copy of the Material Safety Data Sheet/Safety Data Sheet must be submitted in comp
13、liance with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) requirements or other country-specific MSDS/SDS requirements. In addition, product MSDS/SDS submissions must be in compliance with specific country General Motors TMC003 Material Safety Data Sheet/Safety Dat
14、a Sheet guidance documents where available. 5.6 All materials supplied to this standard must comply with the requirements of GMW3059, Restricted and Reportable Substances for Parts. 6 Approved Sources Engineering qualifications of an approved source are required for this standard. Only sources liste
15、d in the GM Materials File under this standard number have been qualified by Engineering as meeting the requirements of this standard. For other GM locations, the responsible Engineering group should be contacted to obtain the approved source in that individual country. 6.1 Approval and Quality Assu
16、rance Procedure. All raw materials shall be approved and regularly inspected for its quality prior to and during mass production delivery according to approval and quality assurance procedure for chemical raw materials (Spec.
