MIL-PRF-3572B
6. NOTES
(This section contains general or explanatory information that may be helpful, but is not mandatory.)
6.1 Intended use. The lubricants are considered military unique since the majority of use is on
gun barrel/gun slide bearing assemblies associated with Navy guns. The use of the lubricants are
critical to affecting the accuracy of the guns. The requirements of the lubricants, that impact the
performance of the lubricants, are not commercially available. General descriptions of varying
uses for each of grades A, B, and C are specified in 6.1.1, 6.1.2, and 6.1.3.
6.1.1 Grade A. Grade A lubricant is suitable for the lubrication of machine gun housing guides,
windshield wipers, and other lightly loaded sliding members exposed to the weather for both low
and elevated temperatures.
6.1.2 Grade B. Grade B lubricant is suitable for the lubrication of gear trains of torpedoes.
6.1.3 Grade C. Grade C lubricant is suitable for the lubrication of medium or heavy duty gun
slides without causing excessive resistance to counter recoil at ambient temperatures down to -23° C.
It should retain sufficient lubricating properties to permit free recoil and counter recoil when the gun
is heated as a result of sustained fire.
6.1.4 Warning. The lubricant will not be used if there is a corrosion concern and should never
be used where dissimilar metals are present.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of this specification.
b. Grade and size required (see 1.2).
c. Issue of DoDISS to be cited in the solicitation, and if required, the specific issue of
individual documents referenced (see 2.2.1, 2.3).
d. Conformance inspection (see 4.2).
e. Inspection condition (see 4.2.1).
f. Packaging requirements (see 5.1).
6.3 Part Identification Number (PIN). The following part identification number procedure is for
government purposes and does not constitute a requirement for the contractor.
