gal\) maximum] volatile organic content \(VOC\) complying paint. The paint is a special-purpose white alkyd enamel \(Formula Number 30\) for interior use, either primed steel or primed aluminum \(see 6.1\). This product may be used wherever VOC air pollution regulations apply. Product is supplied in a single can and used as supplied without thinning.

MIL-DTL-1115E

4.5.3 Hazardous solvent content. Hazardous solvent content shall be determined in accordance with Methods

7356 and 7360 of FED-STD-141. Solvent fractions shall be identified in accordance with ASTM E1252. Test

results shall be recorded as percent by weight of the total enamel. The test results for each solvent shall be as

specified in 3.3.2 and table VI.

4.5.3.1 Alternate analysis methods. Manufacturer may use other analysis methods if such methods are shown

to identify and quantify the hazardous air pollutants with the accuracy required (see 6.3).

4.5.4 Volatile organic compounds (VOC). VOC tests shall be conducted on enamel prepared for application in

accordance with the manufacturer's ASTM F718 data sheet. The VOC test shall be conducted in accordance with

40 CFR CH.1, Part 60, Appendix A, (EPA) Method 24 and shall be in compliance with the requirements of table III.

4.5.5 Drying oil acids. The unsaponifiable, drying oil acids shall be determined on the isolated vehicle and

shall conform to table II.

4.5.6 Phthalic anhydride. Determine phthalic anhydride content of the non-volatile vehicle. Phthalic anhydride

shall be in accordance with table II.

4.5.7 Flexibility. Flexibility shall be determined in accordance with ASTM D522. The enamel shall be applied

to a flat metal plate of approximately 31 gauge coated with a dry film thickness of 0.025 mm (0.001 inch + 0.0003

inch) of TT-P-645 primer by means of a doctor blade capable of yielding a dry film thickness of 0.025 mm (0.001

inch + 0.0003 inch). The panel shall be allowed to air-dry for 2 hours then baked for 24 hours at 100 to 105 �C (212

to 221 �F). The panel shall then be removed from the oven and allowed to stand for 30 minutes at laboratory

temperature [nominal 23 �C (73 �F)]. The panel shall then be bent over a 3.2-mm ( -inch) mandrel or a tapered

mandrel where the minimum diameter is 3.2 mm ( -inch) and the film examined at the bent under a magnification

of five diameters. Flexibility shall be as specified in 3.4.3.

4.5.8 Condition in container. A container of the product in the size ordered shall be inspected. The product

shall be equilibrated to test laboratory conditions [nominal 23 �C (73 �F)]. Evidence of pressure or vacuum in the

unopened container shall be noted. The container shall then be opened and examined in accordance with Method

3011.1 of FED-STD-141 for evidence of skinning, corrosion of container interior, odor of putrefaction, rancidity or

souring, gel bodies, and hard settling. If the sample is in a 1-liter (1-quart) or smaller container, the character of the

lower (or settled) layer shall be determined with a spatula as specified in ASTM D869. If the sample is larger than 1

liter (1 quart), this step shall be omitted. The enamel shall be hand-stirred 300 stirs in 2 minutes with a spatula

appropriate to the container, stirring so as to ensure uniform distribution of any settled material. Immediately after

stirring, the consistency of the enamel shall be measured using the Krebs-Stormer viscometer. The enamel shall be

applied to a test panel and after it has dried, the enamel film shall be examined for grains 0.8 mm (1/32-inch) in

diameter, even larger gelatinous lumps, and streaks caused by such grains or lumps. The condition of the product

shall be as specified in 3.4.5.

4.5.9 Storage stability.

4.5.9.1 Full container. Storage stability shall be tested in accordance with ASTM D1849. A container of the

product of the size ordered shall be stored at the temperature recommended in the manufacturer's data sheet or

ASTM F718 for a period of 1 year. After completion of 1 year, the stored sample shall be equilibrated to test

laboratory conditions [nominal 23 �C (73 �F)]. Evidence of pressure or vacuum in the unopened container shall be

noted. The container shall then be opened and examined in accordance with Method 3011.1 of FED-STD-141 for

evidence of skinning, corrosion of container interior, odor of putrefaction, rancidity, or souring. If the sample is in a

1-liter (1-quart) or smaller container, the character of the lower (or settled) layer shall be determined with a spatula

as specified in ASTM D869. If the sample is larger than 1 liter (1 quart), this step shall be omitted. The enamel

shall be hand-stirred 300 stirs in 2 minutes with a spatula appropriate to the container, stirring so as to ensure

uniform distribution of any settled material. Immediately after stirring, the consistency of the enamel shall be

measured using the Krebs-Stormer viscometer. The enamel shall be applied to a test panel and after it has dried the

enamel film shall be examined for grains 0.8 mm (1/32-inch) in diameter, even larger gelatinous lumps, and streaks

caused by such grains or lumps. The condition of the product shall be as specified in 3.4.5.1.1.
