    5、 While still in the cold box drop the steel ball to the middle of the specimen from a height of 1000 mm. 3.5 TENSILE STRENGTH (ASTM D 412, Die C; specimens to be cut from plane areas of finished part) 3.5.1 Original, min 175 N/cm2 3.5.2 After Humidity Ageing, max -15% (48 h at 38 +/- 2 C and 98 +/-

    6、2% relative humidity) 3.5.3 After Heat Ageing No loss (14 d at 90 +/- 2 C, 1 h at room temperature) 3.5.4 After Immersion in Engine Oil, max -15% (48 h in Oil No. 1 of ASTM D 471 at room temperature) 3.5.5 After Immersion in Water, max -15% (48 h in distilled water at room temperature) 3.6 TEAR STRE

    7、NGTH, min 220 N/cm (ASTM D 624, Die C; specimens to be cut from plane areas of finished part) 3.7 FINISHED PART REQUIREMENTS 3.7.1 Dimensions As specified on Engineering drawing 3.7.2 Mass The tolerance in mass of finished part for any one supplier shall be maximum +/- 10%, based on the recorded mas

    8、s of his originally approved sample. ENGINEERING MATERIAL SPECIFICATION SS-M99G9514-A Printed copies are uncontrolled Copyright 2006, Ford Global Technologies, LLC Page 3 of 5 3.7.3 Heat Stability The finished part shall show no evidence of delamination, no visible shrinkage or distortion, respectiv

    9、ely it shall not warp to an extent that would affect its use in ultimate assembly. Furthermore, it shall show no change in appearance when compared with the original unaged part. Test Method: The finished part shall be subjected to a temperature of 90 +/- 2 C in a mechanically convection air dry ove

    10、n for 24 hours. Examine after cooling to room temperature. 3.7.4 Environmental Cycling The finished part shall show no evidence of delamination, no visible shrinkage or distortion respectively, it shall not warp to an extent that would affect its use in ultimate assembly. Furthermore, it shall show

    11、no change in appearance when compared with the original un-aged part. Test Method: T he finished part shall be subjected 3 times to the following cycle in the sequence indicated below: 16 h at 38 +/- 2 C and 98 +/- 2% relative humidity 8 h at 80 +/- 2 C 3 h at -40 +/- 2 C Examine after cooling to ro

    12、om temperature. 3.7.5 Cold Resistance after Ageing No cracking. Test Method: 1) Expose the finished part to 90 +/- 2 C for 120 hour. 2) After cooling to room temperature store the part and a steel ball of 30 mm in dia and 225 g for 4 hours at -40 +/- 2 C in a cold box. 3) Place the test specimen par

    13、t horizontally on a base plate and normal to the direction of impact. 4) While still in the cold box drop the steel ball to the middle of the test part from a height of 1000 mm. 3.7.6 Moisture Absorption, max 20% Test Method: 1) Weigh finished part nearest to 5 g. 2) Condition the part in suspended

    14、position at 98 +/- 2% relative humidity and 38 +/- 2 C for 24 hours. ENGINEERING MATERIAL SPECIFICATION SS-M99G9514-A Printed copies are uncontrolled Copyright 2006, Ford Global Technologies, LLC Page 4 of 5 3) After 1 hour at room temperature weigh the part nearest to 5 g and determine increase of

    15、weight in percentage based on original weight. 3.7.7 Mildew Resistance The material shall be free from mildew and malodor. There shall be no visible changes evident after drying. Test Method: 1) Cut from finished part a piece of 50 x 50 mm and soak with distilled water. 2) Place test piece in a beak

    16、er glass of one liter capacity, and cover tightly with a lid. Store at 35 +/- 2 C for 14 days. 3.7.8 Resistance of Coating to Various Test Reagents The finished part shall not dissolve, exhibit tackiness or delaminate when rubbed lightly for 15 seconds with a cotton cloth soaked with each of the fol

    17、lowing test reagents. Use a separate specimen for each test reagent. Test Reagents: 1) Oil No.1 of ASTM D 471 2) Brake fluid, SA-M1C9101-A 3) Sulphuric acid (10% by weight in distilled water) 4) Longlife coolant SS-M97B9101-A (50% by weight in distilled water) 5) Rust preventive compound SK-M7C9552-
