7、ercent - 0.1 Nonvolatile matter, percent 21 - Tag closed cup flash point, oF 142 - Biodegradability of surfactant present, percent 90 - 3.4 Performance. The cleaning compound shall foam, adhere, and clean at least as effectively as the control formula (see table II) similarly packaged when both are
8、tested. Table II. Control Formula Ingredients Percent by Weight Water 20.8 Tetrapyropotassium phosphate 2.5 Sodium metasilicate (Na2SiO3.5H20) 0.7 Potassium Chromate 0.1 Ethylene Glycol Monobutyl Ether 5.0 Potassium Hydroxide (45 percent by weight) 4.2 Oleic Acid 8.3 (Mix above ingredients in the or
9、der given. Check pH. Adjust the pH to 9.0 + 0.5 with Potassium Hydroxide or Oleic Acid, if required.) Solvesso 150 41.7 Cyclohexanol 2.8 Monoethanolamine 6.7 Dodecyl Benzene Sulfonic Acid (98%) 7.2 (Adjust pH to 8-11 with Potassium Hydroxide, if necessary) 3.4.1 Effect on painted surfaces. The clean
10、ing compound shall cause no streaking, fading, or blistering of the aircraft paint system and shall not cause a decrease of surface hardness greater than one pencil in accordance with ASTM F502-08. 3.4.2 Temperature stability. The cleaning compound shall not layer or separate when observed at a temp
11、erature of 60 + 2oC (140 + 4oF) for six hours. Likewise, the cleaning compound shall be homogenous when observed at a temperature of -18 + 5oC (0 + 9oF) for one hour. 3.4.3 Hard water stability. When a 1:9 dilution with 10 grain hard water is performed, the cleaning compound shall show no signs of s
12、eparation. 3.4.4 Emulsibility. When mixed with water, the cleaning compound shall form a homogenous emulsion. It shall not show any free solvent and no more than 2 ml of free water. 3.4.5 Corrosiveness. Aluminum alloy, clad aluminum alloy, magnesium alloy, titanium alloy, polished aluminum alloy, st
13、eel and cadmium plated steel shall show no trace of corrosion. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59921 3 3.4.6 Effect on acrylic base plastics. The cleaning compound shall cause no crazing or cracking of stressed acrylic plastic. 3.
14、4.7 Corrosion between the faying surfaces. There shall be no corrosion between faying surfaces of clad aluminum. 3.4.8 Effect on salt-coated surfaces. The cleaning compound, when applied to a salt-coated surface, shall result in no non-rinsable film. 3.4.9 Accelerated storage stability. The aged sam
15、ple of cleaning compound shall show no marked change in color and uniformity, nor shall it pit, corrode or cause uneven darkening of steel surfaces, and shall give a soil removal value not less than 95% of that which is obtained with the unaged cleaning compound. 3.4.10 Storage stability. After stor
16、age of 6 months, the cleaning compound shall not separate, crystallize or deteriorate, affect the metal strip, show any evidence of incompatibility, nor shall the storage container show any evidence of distortion, leakage, or internal corrosion. The stored cleaning compound shall then meet the requi
17、rements of this specification, except that the cleaning compound shall give a removal value not less than 95% of that which is obtained with the unaged cleaning compound. 3.4.11 Homogeneity. The cleaning compound, when allowed to stand undisturbed for 72 hours, shall be a clear liquid showing no sep
18、arated solids or phase separation. A faint turbidity shall not be considered objectionable. 4. REGULATORY REQUIREMENTS 4.1 Material safety data sheets (MSDS). Manufacturers shall prepare and submit a MSDS in accordance with FED-STD-313, “Material Safety Data, Transportation Data and Disposal Data fo
19、r Hazardous Materials Furnished to Government Activities” and meeting the Code of Federal Regulations (CFR) requirements of 29 CFR 1910.1200, “Hazard Communication.” 4.2 Toxicity. The cleaning compound shall have no adverse effect on the health of personnel when used for its intended purpose. The ma
20、nufacturer shall certify that the cleaning compound contains no substance known to be toxic to the user under normal conditions of use. 5. PRODUCT CONFORMANCE PROVISIONS 5.1 Responsibility for inspection. The contractor is responsible for the performance of all inspections, examinations, and tests.
