SCOPE. T

2、his commercial item description (CID) covers a metal polish used for polishing unpainted aluminum and aluminum alloy surfaces of aircraft. The abrasive quality of the polish enables it to remove tarnish and produce a high lasting shine. The polish shall not be used on aluminum aircraft surfaces that

3、 are to be painted with organic coating materials, unless silicone residue is removed with xylene prior to painting. 2. CLASSIFICATION. The metal polish shall be of the following types: Type I - Liquid. (May be used to polish a surface that will be coated with a waterproof Type II - Paste. (May be u

4、sed at sub-zero temperatures.) liquid wax.) 3. SALIENT CHARACTERISTICS. 3.1 Material. The formulation of the polish shall be optional with the manufacturer except as restricted by the requirements specified herein. 3.1.1 Toxicity. The polish shall have no adverse effect on the health of personnel wh

5、en used for its intended purpose. 3.2 Phvsical Properties. The polish shall conform to the requirements in table I.

8、3.2.3 3.2.1 Settling Number (Twe I onlv). Place 50 milliliters (mL) of well-mixed Type I polish in a test tube. Cap the tube and allow it to remain undisturbed in an upright position for 24 hours. After the settling period, invert the test tube repeatedly until the solid matter is dislodged and begi

9、ns to disperse evenly. Record the number of inversions as the settling number. 3 2.2 Low-Temperature Stability. Place approximately 1 O0 mL of Type I polish or 1 O0 grams of Type II polish in each of two 125-mL wide-mouth Pyrex jars and stopper the jars. Set aside one of the jars at 70 to 77 OF (21

10、to 25 OC) for the duration of the test period as a control sample. Place the second jar containing the test sample in a cold box maintained at 14 k4 OF (-10 f2 OC) for 2 hours. At the end of the 2-hour period, remove the jar from the cold box and immerse it in a water bath maintained at 117 f2 OF (4

11、7 +1 OC) for 1 hour. Remove the jar fiom the water bath, dry, and again place it in the cold box at 14 k4 OF (-1 O f2 OC) for 2 hours. At the end of the second 2-hour period, remove the jar from the cold box and immerse it in the water bath maintained at 117 +;! OF (47 fl OC) for 1 hour. Remove the

12、jar from the water bath, dry, and again place it in the cold box at 14 k4 OF (-10 +z OC) for a third 2-hour period. At the end of this period, remove the jar from the cold box and allow it to remain at room temperature for 16 hours. For Type I polish, shake the jar containing the test sample vigorou

13、sly by hand; for Type II polish, stir the contents of the jar. Compare the appearance of the test sample to the control sample. 3.2.3 Abrasive Number. Clean and weigh two 0.05- by 3- by 6-inch aluminum panels conforming to QQ-A-250/5. Cover one of the panels with a thin coating of polish. Place the

14、second panel on the coated panel and rotate 25 times in moderate circular motion. Separate the panels and wipe clean with a soft cloth saturated with acetone. Reweigh and determine the weight loss. Record the weight loss in milligrams as the abrasive number. 2 Provided by IHSNot for ResaleNo reprodu

The polish shall be capable of polishing a tarnished aiuminum surface to produce a reflectance reading of fi-om 10 to 30 when measured with a reflectometer. The reflectance shall

16、 not change over a 24-hour period. 3.3.1 When Type II polish is applied to a tarnished aluminum surface at O OF (-1 8 OC), it shall meet the requirements specified in 3.3. 3.3.2 Polish that has been restored after being temperature cycled as specified in 3.2.2 shall produce a reflectance reading not

17、 less than 90 percent of the reflectance reading produced by the low-temperature control sample when applied to a tarnished aluminum surface. 3.4 Ease of Removal and Corrosiveness. Residual polish shall be easily removed fiom a tarnished aluminum surface that has been polished and dried. There shall

18、 be no discoloration or evidence of corrosion after the surface has been wiped clean. 3.5 Water and Salt Sprav Resistance (Type I only). Aluminum surfaces treated with Type I polish and coated with a waterproof liquid wax shall resist water and salt spray. 3.6 Storage Stability. The polish shall sho

19、w no visible evidence of deterioration after storage in ambient conditions for 6 months. 4. REGULATORY REQUIREMENTS. 4.1 Regulatory Requirements.
