GENERAL INFORMATION The information below is provided for clarification and assistance in meeting the requirements of this specification. 4.1 INITIAL SUPPLIER APPROVAL For initial approval, the supplier must furnish the following information for each grade: . A plan detailing how each

10、requirement of para 3 will be controlled on a continuing production bases. . Test results from a typical production sample for the requirements outlined in para 3. . Tensile strength, yield strength and elongation histograms including mean and standard deviation values. Data shall consist of a minim

11、um of 40 measurements for each property taken from a minimum of 20 coils while the process is operating in statistical control. . NDT inspection method outlined in para 3.4. . Paintability test results from typical production samples as outlined in para 4.2. ENGINEERING MATERIAL SPECIFICATION WSB-M1

Upon approval, the material will be added to the Engineering Material Approved Source List. 4.2 PAINTABILITY TEST METHODS Material supplied to European Automotive Operations (EAO) shall meet the requirements of WSK-M2P136-A. Material

13、 supplied to North American Automotive Operations (NAAO) shall meet the following requirements: . Material intended for Class 1 surface applications shall meet the requirements of ESB-M2P130. . Material intended for Class 2 and 3 surface applications shall meet the requirements of ESB-M2P129. A Clas

14、s 1 surface shall be specified for parts of the body or front end sheet metal that are exposed after paint or trim. A Class 2 surface shall be specified for parts of the body not covered by trim materials but exposed to view when the car doors or enclosure lids are in an open position. Class 3 metal surface specifications are parts that are wholly or partially concealed during normal use of the vehicle. Parts such as fender aprons, floor pans and unexposed underbody structural members typify parts that would be specified as Class 3.
