Remove from fixture and examine for cracks or breaks. None are allowed.

19、Proof pressure test at 35 kPa of water or air under water may alternatively be used after 135% elongation to indicate pass or fail. Use production hose clamps and mandrels simulating production tube end form. 3.25 HOSE IDENTIFICATION The colored tracer cord in the reinforcement of the hose may be us

20、ed for source identification. The color shall be determined between Purchasing and the supplier. The word gas/fuel and the coding described below shall appear on the outer cover of the hose in contrasting color and repeated at intervals of 60 mm or less. Mandrel cured hose may be coded once per part

21、. The following format is recommended: a) Supplier identification code. b) Date of manufacture (week, year) and plant designation if supplier has more then one plant producing hoses to this specification. No space between letters. Mandatory on hoses longer then 80 mm only. c) Ford trademark on hoses

22、 longer then 150 mm. d) All of the above printing shall be clearly and legibly printed letters of 4.5 - 6 mm in height and width. When hose is less then 80 mm long, width of letters may be reduced to 3 mm. The following code format is recommended, but not mandatory: G 2 01 Where: G = Plant Designation 2 = Year (single digit) 01 = Week (2-digit number)
