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
