10、PONSIBILITY All materials supplied to this specification must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved under this specification, whether or not such changes affect the materials ab
11、ility to meet the specification requirements, the Supplier shall notify the affected Purchasing, and Materials Engineering activities (with reasons) of the proposed changes. Upon notification of the Company, further instructions will be provided. Note: Suppliers should be prepared to provide test da
12、ta and samples demonstrating compliance to this specification, if requested. Substance restrictions imposed by regulations or Company direction applies to the materials addressed by this document. The restrictions are identified in Restricted Substance Management Standard WSS-M99P9999-A1. 4. APPROVA
13、L OF MATERIALS Materials defined by this specification for direct supply to the Company must have prior approval. Certain materials subcontracted by part suppliers may also require prior approval. These include materials critical to the Companys business for regulatory, safety, environmental or comp
14、atibility requirements or contractual agreements. Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Materials Engineering activity. Upon request, the Supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of this specification.
