31、 II on unworked grease. The physical values specified in table I apply to the average of determinations made on the sample. 4.3 Qualification inspection. Qualification inspection shall consist of all the tests specified in table II. 4.3.1 Sampling. Qualification test samples shall consist of a minim

32、um of 6.81 kg (15.0 lb.) of grease. 4.4 Conformance inspection. The conformance inspection shall consist of the following tests specified in table II: worked penetration, worked stability, steel on steel wear, oil separation, odor, low temperature torque, load carrying capacity, evaporation, droppin

33、g point, dirt, corrosiveness (copper strip), and workmanship. The inspection shall be conducted on samples taken in accordance with 4.4.1. 4.4.1 Sampling for tests. Select two 2.95 kg (6.5 lb.) containers of grease, taken at random from each filled lot (see 6.4). For users who obtain grease in large

34、 containers, samples shall be selected in accordance with ASTM-D4057. One sample shall be used for tests and the other shall be retained. If any test result does not comply with the stated requirement, the test in question shall be repeated on the retained sample: if the sample fails again, the lot

35、shall be rejected. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-81322G 4.5 Test methods.

40、hout license from IHS-,-,-MIL-PRF-81322G 4.5.2 Storage stability. The storage stability shall be in accordance with FED-STD-791, Method 3467, and the following: Temperature of 38 3 C (100 5 F) to be maintained for 6 months. After determination of unworked penetration, the unworked penetration sample

41、 shall be stored at 38 3 C (100 5 F) for an additional 6 months. The sample shall be covered in such fashion to provide an air space above the grease and to prevent the surface of the grease from being disturbed. The sample shall then be examined for presence of crystalline material. 4.5.3 Compatibi

42、lity. Fill standard grease cups with equal volumes of the grease being tested and previously qualified greases. The cup shall be filled by alternately adding 60 grams of each of the two greases being tested, until the cup is full (approximately 454 grams). Mix the two greases by working the sample f

43、or 60 double strokes in accordance with the worked penetration procedure of ASTM-D217 and then let the mixture stand undisturbed for seven days at 18.0 to 29.5 C (65 to 85 F) and 50 10 percent relative humidity. Examine the worked penetration and then the worked stability in accordance with table II

44、, using the same sample of grease mixture for both tests. Small amounts of fresh grease may be added to the worker cup just prior to the worked stability test, as needed to maintain a full cup for testing. 4.5.4 Odor. The odor of the grease shall be observed immediately upon opening the test contain

45、er for conformance to table I. 4.5.5 Toxicity. To determine conformance to 3.6, the grease shall be evaluated via a Health Hazard Risk Assessment (HHRA) which will be performed by the Navy Environmental Health Center (NEHC) (see 6.2 and 6.9). 5. PACKAGING 5.1 Packaging. For acquisition purposes, the

46、 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

47、maintained by the Inventory Control Points packaging activity within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or

48、 by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature which may be helpful, but is not mandatory.) 6.1 Intended use.
