REQUIREMENTS: 3.1 Qualification: The packings furnished under this specification shall be a product w
17、hich has been tested and passed the qualification tests specified herein and has been listed on or approved for listing on the applicable qualified products list.3.2 Materials: This specification originally required a specific formulation which was developed under an Air Force Materials Laboratory c
18、ontract. This exact formulation is no longer required but the formulation shown below is recommended since it will meet the requirements of this specification when properly processed.1.

20、SAE AMS-P-83461- 4 -3.2 (Continued):The cure shall be 4 minutes at 370F. This cure has been used successfully in molds which are attached to the plates of curing presses. If the molds are not attached to the platens other curing conditions will have to be used. The alternate cure must be equivalent
21、to the 4 minutes at 370F cure and the material must meet the physical property requirements of this specification.A very significant difference in the ability to withstand dynamic cycling has been noted between batches of this material. Physical property tests do not show significant differences. It
22、 appears that the age of the Varox may be a factor although this has not been proven. Work is continuing to attempt to find the exact causes of the differences in cycling. In the interim, fresh Varox should be used to make this compound. This is particularly important during production because cycli
23、ng tests are not conducted as a part of quality conformance inspection. Dynamic cycling tests shall be run on samples of production batches of this material at various intervals at the discretion of the qualifying agency.3.3 Dimensions and tolerances: The dimensions and tolerances of O-rings procure
24、d to this specification shall conform toMIL-P-83461/1 or MIL-P-83461/2.3.4 Physical properties: The physical properties of the rubber shall conform to the values given in Table I.AMS-P-83461 SAE AMS-P-83461- 5 -Table I.

Failure is determined as the number of cycle
31、s at which a test ring leaks a total of 70 ml of hydraulic fluid. Each test consists of 2 test cells containing 2 test rings each. A minimum of 3 test runs shall be conducted making a total of 6 test cells to be treated. The number of cycles until failure shall be recorded. The highest number of cyc
32、les and the lowest number of cycles shall be discarded. The remaining 4 values shall be averaged and that value must be 110,000 minimum for the O-rings to pass the test.3.6 Identification: All O-rings shall be individually packaged.

Cure Date.4. QUALITY ASSURANCE PROVISIONS: 4.1 Responsibility for inspection: Unless otherwise specified in the
34、 contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract or order, the supplier may use his own or any other facility suitable for the performance of the inspection requirements spec
35、ified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements.AMS-P-83461 SAE AMS-P-83461- 7 -4.1.1
36、Responsibility for compliance: All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in this specification shall not rel
37、ieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirement
38、s; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material.4.2 Classification of tests: The inspection and testing of the rubber shall be classified as follows:a. Qualification tests (see 4.3)
39、.b. Quality conformance inspection (see 4.4).4.3 Qualification tests: 4.3.1 Samples: Test samples shall be O-rings conforming to Size -214 of MIL-P-83461/1. Size -218O-rings are also required for the dynamic cycling test (see 4.7). Hardness shall be determined on hardness discs of at least 1/4 inch
40、thickness.4.3.2 Tests: Qualification tests shall consist of all the tests specified in 4.6 and 4.7.4.4 Quality conformance inspection: 4.4.1 Sampling for inspection: Sampling for quality conformance inspection shall be in accordance with MIL-STD-105, except where otherwise indicated herein. Quality
41、conformance tests are required for all production batches of material.4.4.1.1 Batch: A batch shall be the quantity of material compounded on a mill or mixer at one time. A batch will always have to include M83461/1 -214 O-rings and hardness discs for quality conformance tests. A batch shall consist
42、of a maximum of 200 pounds. Quality conformance tests shall be conducted on each 200 pounds if the batch size is more than 200 pounds.4.4.2 Quality conformance test samples: The test samples shall be Size -214 O-rings conforming to MIL-P-83461/1. Hardness discs shall be used for hardness determinati
