6、plied to these specifications must have prior approval for paintability by the responsible company activity. This approval shall be based on samples prepared to local process and performance requirements. (See para 5.9) 3.10 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must
7、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 ability to meet the specification requirements, the Supplier sha
8、ll notify the affected Purchasing, and Materials Engineering activities (with reasons), of the proposed changes. Upon notification of the Company, further instructions will be provided.

10、e 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 approval. These include materials critical to the Companys busin
11、ess for regulatory, safety, environmental or compatibility requirements or contractual agreements. Suppliers desiring approval of their materials shall first obtain an expression of interest from either Purchasing, Design or Materials Engineering activity. Upon request, the Supplier shall submit a c
12、ompleted 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. 5. GENERAL INFORMATION The information given below is provided for clarification and assistance in
13、meeting the requirements of these specifications. 5.1 DOCUMENT ORIGIN This document was originally compiled as a collaborative effort between Ford Motor Company, Mazda (Mazda Motor Corporation) and Jaguar (Jaguar Cars), part of PAG (PAG is Premier Automotive Group). 5.2 INITIAL SUPPLIER APPROVAL BY
14、FORD (UNCOATED ONLY - For information for coated HSLA steel submissions see WSS-M1P94-A) For initial approval, the supplier should furnish the following information for each variant: . A plan detailing how each requirement of para 3 will be controlled on a continuing basis. . Test results from a typ
15、ical production sample for the requirements outlined in para 3, with the exception that paintability testing should be conducted on one sample. . The intent of para 3.7 is that the Material Supplier should assess material that aims towards the highest chemistry and thinnest gauge (i.e. the most diff
16、icult material to spot weld) for any given grade. ENGINEERING MATERIAL SPECIFICATION WSS-M1A346-A1/A6 Page 6 of 12 Copyright 2013, Ford Global Technologies, Inc. . Mechanical property histograms including mean and standard deviation values. Data should consist of a minimum of 40 measurements for eac
17、h property in para 3.5, taken from a minimum of 20 coils, while the process is operating in statistical control. Upon approval, the materials will be added to the Engineering Material Approved Source List. 5.3 MATERIAL USAGE For materials with a specified thickness below 1.80 mm, (see paras 3.2 Mate
