P-C-111C <br /> 3. 14 Inhibitor stability on evaporation. There shall be no significant <br /> deterioration in corrosion inhibition when the compound is tested as speci- <br /> fied in 4.5. 18. <br /> 3. 15 Carbon loosening ability at room temperature. The compound shall T <br /> loosen carbon at room temperature in 16 hours as effectively as the compari- <br /> son formula of 4.5. 19.2 when tested as specified in 4.5. 19. r <br /> 3. 16 Carbon loosening ability at 130°F. The compound shall loosen carbon <br /> at 130°F. (540c.)—in 4 hours as effectively as the comparison formula of <br /> 4.5. 19.2 when tested as specified in 4.5.20. <br /> 3. 17 Paint stripping abilit The compound shall strip paint as effectively <br /> as the comparison formula of .5. 19.2 when tested in accordance with 4.5.21 . <br /> 3. 18 Storage stability. Type I compound: After 6 months storage (plus <br /> or minus 5 days) , the difficulty in dispersing any precipitate and diluting <br /> the compound as determined by 4.5.22, shall be no greater than with type I <br /> comparison formula similarly stored. Type II compound: The compound shall <br /> show no separation, precipitation or gelation greater than that of type II <br /> comparison formula after 6 months ' storage (plus or minus 5 days) . In addi- <br /> tion, after the six month storage period, the compounds shall be equal in <br /> performance to the comparison formula when tested as in 4.5. 15, 4.5. 16, <br /> 4.5. 17, 4.5. 18, and 4.5.20. <br /> 3. 19 Exposure stability.
