3.4.5 Solids content.
3.4.5.1 Lubricants in non-pressurized cans. Lubricants supplied in non-pressurized cans
shall contain not less than 24 percent (%) by weight of total solids (see 4.3.4.5.1).
3.4.5.2 Lubricants in gas-pressurized cans. Each gas-pressurized can shall contain not
less than 30 grams (g) (1 ounce (oz)) of total solids (see 4.3.4.5.2).
3.4.6 VOC content (type II only). The VOC content of the fluid lubricant shall not
exceed 250 grams per liter (g/L) (33.4 ounces/gallon (oz/gal)) of lubricants less water and
exempt volatile compounds (see 4.3.4.6).
3.4.7 Color. The lubricants supplied in Color 2 (see 1.2.3) shall not be lighter than color
No. 36076 (gray) of FED-STD-595 (see 4.3.4.7).

3.5.1 Storage stability. Following storage at 25 ± 3.0°C (77 ± 5.4°F) for a period of
365 ± 7 days, the lubricant shall be readily dispersed by moderate shaking or stirring and shall
meet all the requirements of this specification (see 4.3.5.1).
3.5.2 Toxicity. The lubricants shall have no adverse effects on human health when used
as intended (see 4.3.5.2).
3.5.3 Restricted materials. The propellant used for aerosol cans shall contain no ozone
depleting substances (ODS). The lubricants shall contain no lead or lead-containing compounds,
graphite or powdered metals (see 4.3.5.3 and 6.9).
3.6 Environmental requirements.
3.6.1 Fluid resistance. After immersion in each of the fluids specified in table I, the
lubricant shall not flake or peel (see 4.3.6.1).
