0.5 g (8 grains) of the extracted pigment contained in a centrifuge tube. Agitate by shaking and centrifuge. A yellow color in the supematant liquid indicates the presence of hexavalent chromium. If the results of the above test are inconclusive, then use the procedure in ASTM D3718 to test for chromium content. Evaluate results for compliance with subparagraph 4e.

b. Condition in the Container. Before stirring the contents of the container in which the material was originally packaged, check for evidence of biological growth and corrosion.

Immerse one-half of the painted panel in distilled water at 25 ̊C (77 ̊F) ± 1 ̊C (2 ̊F). After 18 hours, remove the panel from the water and allow it to dry for two hours at standard conditions. Evaluate for conformance with subparagraph 6e.

g. Abrasion Resistance.

(2) Baked Films. Air dry two of the panels for 24 hours at standard conditions and then bake for 5 hours at 105 ̊C (221 ̊F) ± 2 ̊C (4 ̊F). After baking, condition the panels for 30 minutes at standard conditions and then run the abrasion test as specified in subparagraph 7g(4).

(3) Weathered Films. Air dry the other two panels for 48 hours at standard conditions.

Then subject the panels to accelerated weathering according to subparagraph 7j.

Remove the panels and condition for 24 hours at standard conditions, and then run the abrasion test as specified in subparagraph 7g(4).

(4) Test. Subject the panels to the abrasion test according to ASTM D968, Method A, except that the inside diameter of the metal guide tube shall be from 18.97 to 19.05 mm (0.74 to 0.75 in.). Five liters (1.3 gal) of unused sand shall be used for each test panel. The test shall be run on two test panels. Five liters (1.3 gal) of sand is approximately 7.94 kg (17.5 lb). Evaluate for compliance with subparagraph 6k.

h. Freeze-Thaw Stability. Test according to ASTM D2243 for 3 freeze-thaw cycles. Perform the consistency test according to ASTM D562 and the scrub resistance test as described in subparagraph 7l. Check for conformance with subparagraph 6f.

i. Color.

(1) Sample Preparation. Use the test panels prepared for the accelerated weathering test subparagraph 7j (1).

(2) Daylight Directional Reflectance. For the white paint, determine the directional reflectance before and after weathering according to ASTM E1347. Evaluate for conformance with Table I.

(3) Color Match. For colors other than white and yellow, determine the color difference of the paint before and after weathering according to ASTM D2244 using CIE Illuminant D65 with the 10-degree standard observer. Evaluate for conformance with subparagraph 6g.

(4) Yellow Color Match. Determine the color match for yellow paint before and after weathering according to ASTM D1729 with the daylight illumination represented by CIE Illuminant D75 or D65. Evaluate for conformance with subparagraph 6g (3).

j. Accelerated Weathering.

(1) Sample Preparation. Apply the paint at a wet film thickness of 0.33 mm (0.013 in.)

to four 8 x 15 cm (3 x 6 in.) aluminum panels prepared as described in Method 2013 of Fed. Test Method Standard No. 141. Air dry the sample 48 hours under standard conditions.

(2) Testing Conditions. Test according to ASTM G53 using both ultraviolet light (UV-

BPS-40) and condensate exposure, 300 hours total, alternating 4-hour UV exposure at 60 ̊C (140 ̊F), and 4 hours condensate exposure at 40 ̊C (104 ̊F).

m. Heat-Shear Stability. One pint of the paint is sheared in a Waring Blender at high speed to

65 ̊C (149 ̊F). The blender should have tight fitting lid and be taped to minimize volatile loss. When the paint reaches 65 ̊C (149 ̊F), stop the blender immediately and apply cover.

Let cool a minimum of 12 hours and examine for gelling or other signs of instability.
