20、ce 50 mL of well-mixed Type 1 polish in a 1 x 6 inch (25 x 152 mm) test tube. Cap the tube and allow the tube to remain undisturbed in an upright position for not less than 24 hours. After the settling period, invert the test tube repeatedly until the solid matter is dislodged and begins to disperse
21、 evenly. Record the number of inversions as the settling number.3.2.8 Low-Temperature Stability: The polish shall be restorable to its original appearance by vigorous shaking or by stirring after being temperature cycled as in 3.2.8.1.AMS 1650C SAE AMS 1650C- 4 -3.2.8.1 Place approximately 100 mL of
22、 Type 1 polish or 100 grams of Type 2 polish in each of two 125 mL wide-mouth Pyrex jars and stopper the jars.

Cover one of the panels with a thin coatin
27、g of the polish. Place the second panel on the coated panel and rotate twenty-five times in moderate circular motion. Separate the panels and wipe clean with a soft cloth saturated with acetone. Reweigh and determine the weight loss. Report the weight loss in milligrams as the abrasive number and ex
