Mix 100 mL of the candidate coolant solution with 100 mL of the approved coolant solution in a
8、 250 mL beaker. Heat the mixture to 90 - 95 C. Cover, remove from the heat and let stand 16 - 24 h at room temperature in the absence of light. There shall be no precipitation or separation into phases. Slight cloudiness or separation that does not completely cover the surface of the liquid shall be
9、 acceptable. 3.2.1.8 Storage Stability Must pass test The coolant shall form no permanent gel when tested by the following method. Place at least 60 mL of coolant concentrate in a bottle and cap it snugly. Put it in a circulating air oven at 65 +/- 2 C for 14 days. Remove and allow it to cool to roo
10、m temperature. Examine for gelatinous precipitate. 3.2.2 Phase II 3.2.2.1 Aluminum Cylinder Head Heat - Transfer Corrosion Test (FLTM BL 104-01) Weight Loss, max 1.0 mg/cm2(average of two determinations) 3.2.2.2 Galvanostatic Pitting Test More positive than - (FLTM BL 105-01) 400 mv vs. SCE ENGINEER
