beaker, permit it to cool to 25 ± 3.0°C (77 ± 5.4°F) 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.
4.3.5 Support and ownership requirements verification.
4.3.5.1 Storage stability.
4.3.5.1.1 Lubricant in non-pressurized cans. To determine conformance to 3.5.1, set aside
a one quart qualification sample in a storage area maintained at 25 ± 3.0°C (77 ± 5.4°F) for a
period of 365 ± 7 days. At the end of the storage period, the lubricant shall be subjected to and
pass all applicable tests of this specification.
4.3.5.1.2 Lubricant in gas-pressurized cans. To determine conformance to 3.5.1, select
two new, unused spray cans and place them in a storage area maintained at 25 ± 3.0°C (77 ±
5.4°F) for a period of 365 ± 7 days. At the end of the storage period, the lubricant shall be
subjected to and pass all applicable tests of this specification.
4.3.5.2 Toxicity. The qualifying activity (see 6.3), shall be consulted by the appropriate
departmental medical service to verity that the lubricant does not adversely effect human health
(see 3.5.2).
4.3.5.3 Restricted materials. The contractor shall provide certification attesting that no
graphite, lead or lead-containing compounds, powdered metals, or ozone depleting substances
are used in the manufacturing of either liquid or applied forms (see 3.5.3).
4.3.6 Environmental requirements verification.
4.3.6.1 Fluid resistance. To verify conformance to 3.6.1, the test panels shall be tested
IAW ASTM D2510, Procedure C to verify that no bare metal surface is exposed. A uniform
deposit of powdery material clinging to the removed test tape shall not be considered a failure.
Prior to testing, panels shall be cleaned with aliphatic naphtha, followed by acetone or any
environmentally safe cleaner that cleans surfaces to pass ASTM F22.
4.3.6.2 Thermal stability. To verify conformance to 3.6.2, the test panels shall be
tested IAW ASTM D2511 to verify the absence of flaking, cracking, softening or lifting of the
lubricants (see 3.4.1). Any condensation shall be removed from the test panels with clean,
compressed air prior to the panels being subjected to the film adhesion test. Prior to testing,
