9、l be assessed by a sewing test conducted under normal production conditions with each supplier. The thread must process under production conditions without any reservations. Suppliers deliveries can be rejected because of excessive rates of breakage and/or other manufacturing difficulties (knots, fo
10、reign matter, stretch etc.). In addition, after sewing, the thread shall not exhibit objectionable streaks or any color change in hue or purity of color. 3.7 NUMBER OF KNOTS The thread spool shall be free of all imperfections of such character which would cause the thread to break during sewing. 3.8
11、 IDENTIFICATION Each spool of thread must bear the name of the manufacturer, color suffix, and yarn size. 3.9 PACKING The material must be packed in such a way that in transit no slippage of the layers or any other damage occurs. 4. GENERAL INFORMATION This information given below is provided for cl
12、arification and assistance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications. 4.1 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Produc
13、t Development, and Materials Engineering. 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 the Material Specification. Tested material samp
14、les must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated ENGINEERING MATERIAL SPECIFICATION WSS-M8P22-A Copyright 2017, Ford Global Technologies, LLC Page 3 of 4 quality control documents (Process Failure Mode and Effects
15、 Analysis, Control Plans, Certification testing) with Ford. 4.2 SUPPLIERS ONGOING RESPONSIBILITY All materials 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, whether or not such ch
16、anges affect the materials ability to meet the specification requirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineerin
