MIL-PRF-6086F
3.4 Performance.
3.4.1 Copper corrosion. When tested for a duration of three hours at a temperature of 100°C
using ASTM test method D130, the corrosion produced shall not exceed No. 2 on the ASTM Corrosion
Scale in accordance with the D130 test method.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as
follows:
a.
Qualification inspection (see 4.2).
b.
Quality conformance inspection (see 4.3).
4.2 Qualification inspection.
4.2.1 Qualification sampling. The qualification sample shall consist of a 1-gallon aliquot of the
finished gear oil. At the discretion of the qualifying activity, a separate 1-ounce aliquot of the load-
carrying additive may also be required. Information as noted in 6.4.2 must accompany the submission of
a qualification sample.
4.2.2 Qualification testing. The qualification sample(s) shall be tested as specified in 4.4,
Methods of Inspection.
4.2.3 Retention of qualification. In order to retain a qualified status and listing on the Qualified
Products List (QPL), the manufacturer shall verify by certification to the qualifying activity that the product
complies with the requirements of this specification. Periodic verification by certification shall be
performed in two-year intervals from the date of original qualification. The qualification activity reserves
the right to re-examine the qualified product whenever deemed necessary to determine whether the
product continues to meet any of the specification requirements.
4.3 Quality conformance inspection. The conformance inspection shall include the test for
viscosity, viscosity index, flash point, acid number, copper corrosion, pour point, precipitation number,
foaming characteristics, and load wear index as described in 3.3 and 3.4. Samples shall be labeled
completely with information identifying the purpose of the sample, name of the product, specification
number, lot and batch number (see 6.7), date of sampling, and contract number.
4.4 Method of inspection.
4.4.1 Inspection. Unless otherwise specified, inspection testing shall be performed in
accordance with 4.4.2 and the contractual requirements.
4.4.2 Physicochemical values. Testing shall be performed in accordance with the applicable
methods specified in Table I and 3.4.1. Values for the physicochemical properties specified in section 3
apply to the arithmetic average of the determinations made on the samples for those values that fall
within any stated repeatability or reproducibility limits of the applicable test methods.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to ascertain
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activities within the Military Service or Defense Agency, or within the military service's system
commands. Packaging data retrieval is available from the managing Military Department's or Defense
Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging
activity.
