4.3.4.1 Film adhesion. Test panels prepared per 4.3.2.2, shall be tested IAW

ASTM D2510, Procedure A to verify that no bare metal surface is exposed (see 3.4.1). A uniform deposit of powdery material clinging to the removed test tape shall not be considered a failure.

4.3.4.2 Film appearance and thickness. To determine conformance to 3.4.2, the bonded lubricant specimens shall be examined visually and microscopically at a magnification of 12X for uniformity in color, smoothness and evidence of cracks, scratches, pinholes, blisters, bubbles, runs, sags, foreign matter, grit, rough particles, and separation of ingredients.

4.3.4.2.1 Film thickness on aluminum panels. The thickness of bonded lubricant on aluminum panels prepared per 4.3.2.2 shall be measured IAW ASTM B244 or ASTM D7091 to verify the thickness requirement of 0.008 to 0.013 mm (see 3.4.2).

4.3.4.2.2 Film thickness on steel panels. The thickness of bonded lubricant on steel panels prepared per 4.3.2.3 shall be measured IAW ASTM B499 or ASTM D7091 to verify the thickness requirement of 0.008 to 0.013 mm (see 3.4.2).

4.3.4.3 Spray pattern and duration (lubricants in gas-pressurized cans only). Select a new, unused spray container. The temperature of the spray container and the ambient air shall be

25 2.0°C (77 3.6F). In a vertical position, fasten either a sheet of white paper on which two parallel lines have been drawn 38 mm apart, or a sheet of rectangular coordinate graph paper containing lines 38 mm apart. Position the spray container 250 12.5 mm from the paper. Open the valve fully and, with a stopwatch, determine the time required to exhaust the container. The spray shall be effective for a minimum of 290 seconds. Measure the width of the spray pattern using the parallel lines on the sheet of paper. Agitate the can frequently during the spray procedure (see 3.4.3). (The effective spray is one that carries the pigment together with the resin required for bonding.)

4.3.4.4 Curing time. Maintain the test samples from 4.3.4.3 at 25 2.0C (77 3.6F).

Examine the samples after 30 minutes (for type I lubricants) or 90 minutes (for type II lubricants) and verify that the applied lubricant is dry to the touch IAW 3.4.4. After 18 hours (for type I) or

24 hours (for type II), subject the test samples to film adhesion test IAW ASTM D2510, Procedure A. Lubricant shall be considered fully cured if no loss of adhesion is shown.

4.3.4.5 Solids content.

4.3.4.5.1 Lubricants in non-pressurized cans test. Stir the lubricants thoroughly to provide a uniform dispersion. Weigh 5.0 0.5 g of the lubricant into a weighing dish with a diameter of approximately 70 mm (Fisher Scientific Co. Catalog No. 8-732-102 or equivalent).

Place the dish and contents in a force-draft oven maintained at 49 3.0C (120 5.2F) for

18 1 hour. Remove the dish and contents from the oven, place them in a desiccator, and allow them to cool to 25 3.0C (77 5.4F). Remove the dish and contents from the desiccator and weigh them. Repeat the procedure to constant weight. Calculate the percent by weight of the solid material in the fluid lubricant from the formula:

Percent total solids = Weight of solid materials x 100

Weight of sample

Verify that the percent by weight of solids is not less than 24% (see 3.4.5.1).

4.3.4.5.2 Lubricants in gas-pressurized cans test. Select a new, unused spray container for the total solids test. Place it in an upright position in a solid carbon dioxide cabinet (dry ice cabinet) overnight to reduce the internal pressure. Remove the container from the cold cabinet and immediately pierce a small hole in the top of the container with a sharp punch. Permit the container to warm to 25 3.0C (77 5.4F) in an upright position, in a well-ventilated area.

When all the gas has escaped from the container, remove the top of the container. Transfer quantitatively the contents of the container to a 600 milliliters (mL) (0.16 gal) beaker previously weighed to the nearest 0.1 g (0.004 oz). Rinse the container twice with an appropriate solvent

(as recommended by the manufacturer) or distilled water for water based coating, and add the rinsings to the beaker. Remove the agitator (usually a glass marble or a small steel ball) from the beaker, rinse it with the solvent and return it to the empty container. Add the solvent rinsing used to clean the agitator to the beaker. Place the beaker in an explosion-proof oven operated at

49 3.0C (120 5.2F). Permit the beaker to remain in the oven overnight. Remove the beaker, permit it to cool to 25 3.0C (77 5.4F) and weigh to a constant weight. Calculate the weight of total solids from the following formula:

Weight of beaker and total solids - weight of beaker = Weight of total solids

Verify that each can shall contain not less than 30 g (1 oz) of total solids (see 3.4.5.2).

4.3.4.6 VOC content (type II only) test. The VOC content shall be determined IAW

ASTM D3960 to verify the maximum value of 250.0 g/L (33.4 oz/gal) (see 3.4.6). For the calculation of the VOC content, the weight percent of water shall be determined IAW

ASTM D4017, and the weight percent of the exempt solvents shall be determined IAW

ASTM D4457.

4.3.4.7 Color. To verify conformance to 3.4.7, the Color 2 lubricant (see 1.2.3) shall be visually examined to verify that its color is not lighter than Gray No. 36076 of FED-STD-595.

6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory).

6.1 Intended use. The solid film lubricants covered by this specification is military unique due to requirement that its performance should not be degraded as a result of exposure to the military unique fluids specified in table I. The lubricant is intended for use on aluminum, aluminum alloys, copper and copper alloys, steel, stainless steel, titanium, and chromium and nickel bearing surfaces. Solid film lubricants are often used on weapons, ground vehicles, and ground handling equipment. They are used for thin film lubricant for sliding motion application and under conditions where heavy-load capacity, solvent resistance, and long term corrosion protection are needed. All end items should have the lubricant applied IAW Appendix A of this document. It is useful under the following conditions:

a. Where conventional lubricants are difficult to apply or retain.

b. Where dust and dirt contamination on lubricated surfaces is deleterious.

c. Where temperatures may range from -67.0C to +93.0C (-88.6F to 199.4F).

d. In mechanisms operated at infrequent intervals.

e. In mechanisms that are lubricated for the life of the mechanism.

f. Where long-term corrosion protection is required.

g. Where a dull, dark gray or black non-reflective surface is required.

h. Where a sacrificial lubricant is necessary to carry extremely heavy loads developed in the initial start-up of heavily loaded mechanism designed for fluid lubrication. In operations consisting of reciprocating motion, loaded to 15 pounds per square inch

(psi) (103 kilopascals (kPa)) or less, where contamination with conventional fluid lubricants are probable.

i. To touch up worn surfaces originally coated with lubricant conforming to

MIL-PRF-46010.

j. For sliding motion applications such as plain and spherical bearings, flap tracks, hinges, threads, and cam surfaces.

6.1.1 Use limitations. The lubricants should not be used under the following conditions:

a. In operations consisting of rotary motion above 100 revolutions per minute (rpm) under heavy loads where the possibility of conventional fluid lubricant contamination exists. The cured lubricant film is highly resistant to conventional fluid lubricants, but the high fluid pressures developed in heavily loaded sleeve type bearings drastically reduces the wear life provided by the solid film lubricant film.

b. On bearings containing rolling elements.

6.1.2 Corrosion protection life. This lubricant can be expected to provide corrosion protection for five years in indoor storage and approximately two years protection in outdoor storage when the lubricant is applied over phosphated steel to a thickness of 0.013 mm. Where maximum corrosion protection of steel is desired, the lubricant should be applied over phosphated steel to a thickness of 0.025 mm. This heavier coating can be expected to provide outdoor corrosion protection for approximately four years.

6.2 Acquisition requirements. Acquisition documents must specify the following:

a. Title, number, and date of this specification.

b. Type of lubricants, form of container (pressurized or non-pressurized cans), and color required (see 1.2).

c. If required, the specific issue of documents referenced (see 2.2.1 and 2.3).

c. Quantity of lubricants required.

d. Packaging requirements (see 5.1).

6.3 Qualification. With respect to products requiring qualification, awards will be made only for products which are at the time set for contract award, qualified for inclusion in the applicable Qualified Products List whether or not such products have actually been so listed by that date. The attention of the contractor is called to this requirement, and manufacturers are urged to arrange to have the products that they propose to offer to the Federal Government tested for qualification in order that they may be eligible to be awarded contracts or orders for the products covered by this specification. The activity responsible for the Qualified Products List is the Fuels and Lubricants Technology Team, AMSRD-TAR-D/210 (FLTT), U.S. Army Tank

Automotive Research, Development, and Engineering Center (TARDEC), Warren, MI

48397-5000, and information pertaining to qualification of products may be obtained from that activity. An online listing of products qualified to this specification may be found in the

Qualified Products Database (QPD) at https://assist.dla.mil.

6.4 Subject term (key word) listing.

Aerosol cans

Dry lubrication

Gas-pressurized

Protection

Volatile organic compound

6.5 Reserved.

6.6 End item testing. When possible, it is recommended that film thickness and adhesion be tested when the lubricant has been applied to an end item. Testing with laboratory coupons and test panels does not always correlate with lubricant performance when applied to an actual end item.

6.7 Material Safety Data Sheets (MSDS). Contracting officers should identify those activities requiring copies of MSDS’s prepared IAW FED-STD-313. The pertinent Government mailing addresses for submission of data are listed in FED-STD-313; and 29 CFR 1910.1200 requires that the MSDS for each hazardous chemical used in an operation must be readily available to personnel using the material. Contracting officers should identify the activities requiring copies of the MSDS.

6.8 Explanation of restricted materials. (See 3.5.3)

6.8.1 Exclusion of graphite and powdered metals. In previous experience, graphite, powdered metals, carbon black, charcoal or other forms of inorganic carbon have caused accelerated corrosion, due to the galvanic reaction that occurs between the coated surface and the coating. The exclusion of graphite permits the use of this product in high vacuum, since graphite is not a lubrication solid without moisture or adsorbed air.

6.8.2 Exclusion of lead and lead compounds. Historically, products under MIL-PRF-

46147 were permitted to contain lead compounds because no alternative existed. Products have since been developed that conform to the requirements of this specification but do not require the use of lead compounds. The exclusion is inserted in order to prevent lead pollution.

6.9 Definitions.

6.9.1 Lead-containing compound.

a. Any chemical compound that contains the chemical element Pb.

b. Chemical mixtures containing compounds that contain the chemical element Pb are also considered lead-containing compounds.

6.10. Amendment notations. The margins of this specification are marked with vertical lines to indicate modifications generated by this amendment. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations.

Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations.

A.3. REQUIREMENTS

A.3.1 General application instructions for all metals. Do not touch the pre-treated surfaces with fingers. Stir the lubricants until thoroughly mixed, using a low-shear mixing blade.

A mechanical paint shaker may be used for type I, but is not recommended for type II as excessive foaming with waterborne products may occur. Minor viscosity adjustments to type II may be made by adding deionized water IAW A.3.1.1. Ordinary tap water shall not be used.

Apply the lubricants by brushing, dipping, or spraying to a nominal film thickness of 0.010 mm with no reading less than 0.005 mm or greater than 0.018 mm and permit the coated parts to air dry. The application of the coating to parts shall be as specified in A.3.2 through A.3.7 unless otherwise specified in the contract or purchase order.

A.3.1.1 Deionized water. Any water used for dilution of water-based lubricants shall have a resistivity not less than 1 megaohm-centimeter (M-cm) when measured IAW ASTM

D1125.

A.3.2 Application on aluminum and aluminum alloys. Preclean the aluminum surface with aliphatic naphtha or any other EPA compliant cleaner that sufficiently cleans surfaces to pass ASTM F22. Sulfuric acid anodize IAW MIL-A-8625 and seal the surface.

A.3.3 Application on copper and copper alloys. Preclean the copper surface with aliphatic naphtha or any other EPA compliant cleaner that sufficiently cleans surfaces to pass

ASTM F22. Sandblast the surfaces with 180-220 grit aluminum oxide. Form a black oxide finish on the surfaces.

A.3.4 Application on magnesium and magnesium alloys. Preclean the magnesium surface with aliphatic naphtha or any other EPA compliant cleaner that sufficiently cleans surfaces to pass ASTM F22. Anodize the surface in accordance to ASTM D1732 Class II Type

II or III.

A.3.5 Application on steel. Preclean the steel surface with aliphatic naphtha or any other

EPA compliant cleaner that sufficiently cleans surfaces to pass ASTM F22. Sandblast the surfaces with 180-220 grit aluminum oxide. Phosphate IAW MIL-DTL-16232 (weight should be 11-22 g/m ), type M, class 3 or type Z, class 3.

A.3.6 Application on stainless steels. Preclean the steel surface with aliphatic naphtha or any other EPA compliant cleaner that sufficiently cleans surfaces to pass ASTM F22. Sandblast the surfaces with 120-grit aluminum oxide. Passivate the surfaces with ASTM A967, types nitric 1, nitric 2 or nitric 3, as applicable.

A.3.7 Application on titanium and titanium alloys. Degrease the surfaces to be coated with aliphatic naphtha or any other EPA compliant cleaner that sufficiently cleans surfaces to pass ASTM F22. Sandblast the surface with 180-220 grit aluminum oxide and alkaline anodize.

A.3.8 Engineering tolerances. The operating thickness of this lubricant averages from

0.008 to 0.013 mm per lubricated surface. This thickness seldom requires alteration of established clearances between moving parts. There is one exception. The lubricant coating thickness must be considered in the case of small parts that normally operate with very little clearance. The cured lubricant film is relatively soft and any interference produced by the thickness of the lubricant will cause rapid wear of the lubricant film to the point where interference is eliminated
