Prior to making any changes to the mater
12、ial originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify the affected Purchasing, and Mate rials Engineering activities (with reasons) of the proposed changes. Upon notification of the
13、 Company, further instructions will be provided. Note: Suppliers should be prepared to provide test data and samples demonstrating compliance to this specificat ion, if requested. Substance restrictions imposed by regulations or Company direction applies to the materials addressed by this document.
14、The restrictions are identified in Restricted Substance Management Standard WSS - M99P9999 - A1. 4. APPROVAL 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 approv
15、al. These include materials critical to the Companys business for reg ulatory, safety, environmental or compatibility 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, t he 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.
