DE requirements listed in any of the following paragraphs are intended as maximum target values. Visual ratings will take precedence. 3.1 STATISTICAL PROCESS Suppliers must conform to the

5、 requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as described therein is required for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.2 CONDIT

6、IONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 48 - 67 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. 3.3 APPEARANCE (FLTM BI 109-

7、01) The color, pattern, and finish shall match the approved Design Center master sample, or shall be as specified on the engineering drawing. Note: This webbing is to be manufactured in a four panel weave construction (not including the edges as panels). ENGINEERING MATERIAL SPECIFICATION WSB-M7H22-
