MIL-DTL-15090 Enamel, Equipment, Light Gray \(Navy Formula No.111\)This specification covers a 250-gram per liter \(maximum\) \(2.08 pounds per gallon [maximum]\) volatile organic content \(VOC\) complying paint. The paint is a light gray equipment enamel \(Navy Formula Number 111\) for shipboard use as a topcoat on equipment, machinery, furniture and electrical equipment, such as switchboard installations. This product may be used wherever VOC air pollution regulations apply. The light gray equipment enamel covered by this specification is an air dry, solvent base coating for use in all interior dry areas including applications covered by reactor plant painting schedules. This product is supplied in a single can and used as supplied without thinning.

4.7.2.1 Tantalum and tungsten content. Determine the tantalum and tungsten content of the enamel using any

appropriate spectroscopy test method. Conduct the tests in accordance with the equipment manufacturer's directions

for the use of the instrument. Paint manufacturer is responsible for justifying the test method choice and analytical

accuracy. Test results for tantalum and tungsten shall be as specified in table IV and table V.

4.7.3 Hazardous air pollutant solvents content. Formulation data is to be used by manufacturers in lieu of

testing to demonstrate compliance with hazardous air pollutant requirements of this specification. The coating

manufacturer must provide for each individual HAP a formulation value that will not be exceeded if a sample from

any quality control approved batch of the coating is evaluated in accordance with this paragraph. See 3.5.2.

4.7.4 Phthalic anhydride. Determine phthalic anhydride content of the nonvolatile vehicle.

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

shall conform to table II.

4.7.6 Color testing.

4.7.6.1 Instrumental color deviation determination. Test specimens shall be prepared in accordance with

ASTM D823 Test Methods C or E using a nominal 0.006 in blade film applicator on to a clear plate glass of not less

than -in (nominal) thickness, which has been ground to a uniform finish with 1F carborundum. A standard black

and white Leneta chart is also acceptable. The color deviation shall be determined in accordance with ASTM

D2244 using an instrument having a D65 light source (10-degree observer) or C (2-degree observer), a 45-degree

illumination angle, a 0-degree viewing angle. The instrument shall be calibrated in accordance with manufacturer

instructions and shall be demonstrated to read the color of National Institute for Science and Technology (NIST

[formerly National Bureau of Standards; NBS]) traceable standards with color deviations not greater than allowed in

3.6.2. After calibration of the instrument, measure the CIE color values of not less than two color number 26307 of

FED-STD-595 color cards which were received from the Government not greater than 1 year prior to the date of this

use. Make at least three readings per card taken at 1-inch intervals on the long axis, 1 inch from the edge. Calculate

ΔE for each color card. Determine the mean values of ΔE and the CIE color values for the color cards. If any

individual CIE color value differs from the mean color value by more than 0.05, use a different color card and

recalculate the mean values. These mean values will be used to calculate the color difference values. Measure the

CIE color values of the test enamel using the values of three readings taken at 1-inch intervals on the long axis, 1

inch from the edge. Calculate the mean CIE color values of the test enamel. Calculate the color difference terms. If

using an instrument that automatically calculates the color differences, enter the color card mean values as the base

line for the color difference calculations. The results of the color difference calculations shall be in accordance with

the requirements of 3.6.2.
