P-C-111C <br /> 3.6 Distillation characteristics. When tested as specified in 4.5. 10, the <br /> initial boiling point of the compound shall be not less than 210°F. A com- <br /> plete distillation shall be performed as specified in 4.5. 10. No two temper- <br /> ature readings on duplicate distillations at any one percent recovered shall <br /> differ by more than 5°F. from that obtained for the qualification test sample. <br /> The maximum temperature difference between qualification and acceptance <br /> samples for the same percent recovered shall not be greater than 5°F. <br /> 3.7 Flashpoint. When tested as specified in 4.5. 11 , the flashpoint of the <br /> compound shall be above the initial boiling point of the compound (see 3.6) . <br /> 3.8 Pour point. The pour point of the compound shall be no higher than <br /> 10°F. when tested as specified in 4.5. 12. <br /> 3.9 Emulsification. When the compound is tested as specified in 4.5. 13, <br /> the emulsion or solution formed shall show no sediment, curd, or scum. Cream- <br /> ing or opalescence shall be acceptable. <br /> rr <br /> 3. 10 Phase separation on cyclic freezing. There shall be no precipitation <br /> or phase separation of the compound greater than that of the comparison formula <br /> of the same type when tested as specified in 4.5. 14. <br /> 3.11 Chemical corrosion. The compound, when tested as specified in 4.5.15, <br /> shall cause no greater etching, discoloration or pitting of metals than the <br /> comparison formula of 4.5.19.2. For each metal, no panel from the test com- <br /> pound shall show a weight change in excess of the weight change (C) calculated <br /> for a panel of the same metal after immersion in the comparison formula mix- <br /> tures. Use the following formula to calculate weight change of metal speci- <br /> mens in comparison formula. <br /> C = x + 1.32w <br /> x = average weight change in milligrams for each metal after test in the <br /> 14 comparison formula. <br /> w = range, difference between smallest and largest weight losses (or <br /> smallest and largest weight gains) for each metal in the comparison <br /> formula. Considering both losses and gains as greater than zero <br /> when both occur, range is the sum of the largest weight gain and <br /> the largest weight loss. <br /> 3.12 Galvanic corrosion. The compound, when tested as specified in 4.5.16, <br /> shall cause no greater etching discoloration or pitting of metals than the <br /> comparison formula of 4.5.19.2. For each metal, no panel from test compound <br /> shall show a weight change in excess of the weight change (C) calculated for <br /> a panel of the same metal after immersion in the comparison formula mixture. <br /> Use the following formula to calculate weight change of metal specimens in <br /> comparison formula. <br /> C = x + 1.32 w (see 3.11) <br /> 3.13 Clouding stability. There shall be no evidence of clouding when the <br /> '1 compound is tested in accordance with 4.5.17 <br /> 5 <br />
