ENGINEERING MATERIAL SPECIFICATION WSS-M4D1055-A1 Copyright 2017, Ford Global Technologies, LLC Page 2 of 7 3.4 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.4.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s)

8、, which indicated that the mean and 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.4.2 This specification is based on virgin material and does no

9、t allow the addition of recycled content (PIR/PCR). 3.4.3 The use of regrind is permitted, for economic / environmental reasons. Part manufacturers using this specification must complete DV and PV testing with the allowable amount of regrind and the maximum allowable regrind content must be specifie

10、d on the engineering drawing. Any changes to what is specified on the drawing (no specific amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA). 3.4.4 Materials requiring High Strain Rate, Creep or fiber oriented Tensile M
