REQUIREMENTS 3.1 Qualification For this specification as per OEM requirements. 3.2 Material The compound supplied under this specification shall be a smooth homogeneous mixture, uniform in appearance, free from lumps, abrasive materials, or other undes
30、irable fillers or impurities. There shall be no odor of rancidity or perfume. 3.3 Corrosion on Copper After 24-hour exposure, the compound shall show no green color, no pitting or etching on the copper, nor shall a dark brown or black stain remain on the copper strip after washing with N-hexane. A s
31、light brown stain shall not be cause for failure. 3.4 Toxicity The compound shall comply with REACH and/or TCSA regulations. It shall have no adverse effect on the health of personnel when used for its intended purpose and shall not cause any environmental problems during waste disposal. 3.5 Homogen
32、eity The compound shall be completely homogeneous at the time of inspection or during storage awaiting completion of the qualification tests. It shall possess a smooth greasy consistency without lumps, crusts or granular particles when examined. 3.6 Oil Separation The vehicle of the compound shall s
33、eparate not more than 10% of the compounds weight in 30 hours when tested at 150 F 5 F (66 C 3 C). 3.7 Storage Stability After the compound has been stored for 6 months at a temperature of 150 F 5 F (66 C 3 C), it shall be examined. The compound shall be a smooth homogeneous mixture free from lumps
34、and granular materials. 3.8 Performance There shall be no galling of the stud threads, the nut threads, the nut contacting surface and the corresponding plate contacting surface when the test apparatus is disassembled following the performance test. The average breakaway torque for loosening of the
35、nuts from the studs shall be as specified in 4.4.2.1.4. 3.9 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the operational and mainte
36、nance requirements, and promotes economically advantageous life cycle costs. 4. VERIFICATION 4.1 Classification of Inspections The inspection requirements specified herein are classified as follows: a. Qualification inspection (see 4.2). b. Conformance inspection (see 4.3). SAE INTERNATIONAL AMS3050
37、 Page 6 of 11 4.2 Qualification Inspection Qualification inspection shall be conducted at a laboratory acceptable to the command or agency concerned. Qualification inspection shall consist of examination and tests specified in 4.3 and 4.4. 4.3 Conformance Inspection 4.3.1 Lot For the purposes of sam
38、pling, a lot shall consist of all compound manufactured as one batch. Any container in the sample having one or more defects, or under required fill shall cause rejection of the container and if the number of defective containers in any sample exceeds the acceptable number for the appropriate sampli
39、ng plan as specified in the contract or order, this shall cause rejection of the lot represented by the sample. 4.3.2 Examination of Filled Containers A sample of filled containers selected from each lot in accordance with MIL-STD-1916 as specified in the contract or order shall be examined to verif
40、y compliance with all stipulations of this specification regarding fill, closure, marking and other requirements not involving tests. Containers shall be examined for defects of the container and the closure, for evidence of leakage, and for unacceptable markings; each sample filled container shall
41、also be weighed to determine the amount of the contents. Any container in the sample having one or more defects, or under required fill shall cause rejection of the container and if the number of defective containers in any sample exceeds the acceptable number for the appropriate sampling plan as sp
42、ecified in the contract or order, this shall cause rejection of the lot represented by the sample. 4.3.2.1 Examination of Compound Material Portions of the compound material shall be taken from top, bottom and intermediate parts of the sample of containers and examined visually to determine that the
43、re is no apparent difference in appearance or consistency. The material shall be homogeneous and show a smooth greasy consistency without lumps, crusts or granular particles. It shall not have an odor of rancidity or perfume. 4.3.3 Sample Material for Testing From each lot, a 5-pound container shall
44、 be selected, sealed and marked. The 5-pound sample specimen shall be retained by the manufacturer or contractor for verification testing, if required, at a later date. 4.3.4 Sampling for Production Check Tests Unless otherwise specified, (see 5.2), from the first lot produced on a contract or order
45、 and thereafter at such intervals as may be considered necessary by the command or agency concerned to verify the consistency of production quality, one 2-pound sample and two 1-pound samples of compound shall be forwarded to a laboratory acceptable to the command or agency concerned. These samples
46、shall meet the requirements of 3.6 and any other tests deemed necessary by the command or agency concerned to determine conformance of the product.
