19、, 7.5% hot test fluid (samples 3 and 4), 10% hot test fluid (samples 5 and 6) and no hot test fluid (samples 7 and 8) in deionized water (ASTM D1193, Type IV minimum, to simulate factory water usage). In samples 1, 3. 5 and 7, place a cast iron coupon per ASTM D1384 section 6. In samples 2, 4, 6 and

20、 8, place a cast aluminum coupon per ASTM D1384 section 6. Volume of fluid is to cover the entire coupon surface. Put all samples in 90C oven for 1 hour. Remove samples from the oven and drain 50% of the fluid volume from them such that that each coupon is 50% immersed and 50% in air. Evaluate coupo

21、n surfaces for darkening, rust, etc. Set the samples in a humidity chamber at 50% humidity and ambient temperature for 4 weeks with lids resting on top but not tightened. Remove samples. Evaluate the coupon surfaces for darkening, evidence of rust or aluminum corrosion is to be noted. Compare the sa

22、mples with hot test fluid against the sample with water alone; sample with hot test fluid is to have better corrosion performance than water alone. Photos are to be provided of each sample. 3.4.2 Storage Stability Hard water and temperature Supplier must report water quality conditions that may adve

23、rsely affect the quality of the hot test fluid (inhibitor depletion, lowered life, etc). The hot test fluid concentrate form, quality and chemical composition shall not be adversely affected, changed or impacted by storage in plant environments under conditions of normal distribution and storage.

24、GINEERING MATERIAL SPECIFICATION WSS-M97B56-A1 Copyright 2013, Ford Global Technologies, LLC Page 4 of 5 Hard water solution - Prepare hard water by adding 275mg of calcium chloride (CaCl2) to 1 liter synthetic corrosive water described in the test solution section of ASTM D1384. Prepare six 100 ml

25、hot test fluid and hard water samples using the test coolant and the hard water solution. Samples are to have hot test fluid concentrations of 5% (samples 1 and 2), 7.5% (samples 3 and 4) and 10% (samples 5 and 6). Put all samples in clean, glass bottles for testing. All samples must pass hot and co

26、ld storage stability testing for the coolant to pass. 3.4.2.1 Hot Storage Stability - Samples 1, 3 and 5 are heat storage tested in a circulating air oven at 90 +/- 2 C for 4 weeks. Allow to cool to room temperature. Check for precipitates, deposits, gelation and phase separation. “Fish eyes” on the

27、 top (from defoamer) is acceptable. If anything other than “fish eyes” is present, such as gel or material in solution or precipitate, terminate test and write as failure. Analyze mixture to determine effect to the hot test fluid. 3.4.2.2 Cold Storage Stability - Samples 2, 4 and 6 are cold storage

28、tested at -40C for 4 weeks. Allow to reach room temperature. Check for precipitates, deposits, gelation and phase separation. “Fish eyes” on the top (from defoamer) is acceptable. If anything other than “fish eyes” is present, such as gel or material in solution or precipitate, terminate test and co

29、nsider as a failure. Analyze mixture to determine effect to the hot test fluid. 3.4.3 Compatibility with Engine Coolants Aqueous hot test fluids only. List of coolants for compatibility testing to be supplied by Ford FCSD, Materials Engineering and/or Product Development PTI Cooling. Test Method Pre

30、pare 5 samples, of 500 ml volume, of 50% coolant concentrate and 50% deionized water (ASTM D 1193, Type IV minimum water to simulate factory fill usage). Label sample bottles 1, 2, 3, 4 and 5. Add 5%, 7%, 8% and 10% by volume of concentrated aqueous base inhibitor to samples 1, 2, 3 and 4, respectiv

31、ely; leave sample 5 as is. Allow samples to sit for a period of 4 weeks at ambient temperature then heat at 90C for a period of 2 weeks. Observe the samples weekly for any change in appearance, such as gelling, precipitation, phase separation. (French square-type bottle may aid visual check.) Analyz

32、e mixture to determine effect to the hot test fluid. Any changes, other than “fish eyes” deem the hot test fluid incompatible with the coolant. 3.4.4 Trial Evaluation of Engine Corrosion Protection - Simulated Shipping and Storage Test Method In an actual plant, perform a trial of 10-25 engines cont

33、aining both iron and aluminum. Engines are to be hot tested using 10% hot test fluid for aqueous fluid with 90% treated water (per above) or 50% coolant concentrate and 50% treated water (per above). Engines are then drained using current plant procedure. Engines are placed in storage for 3 4 months

34、. After storage, engine coolant passages should be examined visually (jury appraisal) for any sign of corrosion. This would include bore-scope inspection of water passage areas of block and cylinder head. Ancillary metal components, such as water pump, thermostat housings, thermostats, hose connecto

35、rs, etc. should also be examined for evidence of corrosion. Thermostats should also be examined for deposits and correct operation. Check for crevice corrosion that may occur at component joints or other crevices. Any areas that retain significant amounts of residual hot test fluid should be careful

36、ly examined. ENGINEERING MATERIAL SPECIFICATION WSS-M97B56-A1 Copyright 2013, Ford Global Technologies, LLC Page 5 of 5 If there is residual hot test fluid / coolant available, a sample is to be taken and analyzed. If corrosion inhibitors are depleted, there are metals in solution from corrosion, or

37、 there are visual effects from storage (color change, preciptates, floating material), this is to be considered failure and must be reported and investigated in conjunction with Materials Engineering and the hot test fluid / coolant supplier. Note: Each plant should determine suitability of hot test

38、 fluid corrosion protection. This can be accomplished by hot testing a sample of current engines (reference latest version of engine specific ES-BR3E-6007-XX). Engines should be hot tested and drained using current plant procedure and then placed in storage for a time representative of maximum curre

39、nt storage and shipping times. Fluid concentration used must be representative of that to be used by the plant. Any significant corrosion evidence is cause for failure and should be reported and investigated in conjunction with Materials Engineering and the relevant component engineers. 4. GENERAL I

40、NFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications. This product should be stored above -5C and preferably at plant ambient temperatures. Periods

41、of exposure to temperatures above 35C should be minimized. It can be stored for a minimum of 5 years in unopened containers without any effect on the product quality or performance.
