If qualification tests are performed at the manufacturers facility or at a t
34、est facility without ISO/IEC 17025 accreditation with a relevant scope, test shall be witnessed by a QPG member, designated QPG representative, PRI Auditor, or verified by OEM qualification test. SAE INTERNATIONAL AS6449C Page 5 of 11 3.2 Material Requirements 3.2.1 General Requirements The lubrican
35、t, applied in accordance with AS6450, shall meet the following requirements. The material shall meet all the requirements of this specification at any time within 12 months from the date of manufacture when material is stored from 40 to 100 F (4 to 38 C). The cured coating when applied to oxygen and
36、 potable water fittings shall not transfer to hands, packaging material or oxygen and potable water tubes under normal handling conditions. 3.2.2 Bonded Solid Film Requirements Type I and Type II lubricants applied in accordance with AS6450, shall meet the requirements in 3.2 and 3.3, except Type II
37、 lubricant is not required to meet the requirements of 3.3.1. Type III and Type IV lubricants applied in accordance with AS5528 shall meet the requirements of AS5272 Type I and Type II respectively. 3.2.3 Film Appearance and Thickness The cured dry lubricant film shall have a uniform appearance and
38、complete coverage. No voids or buildups in excess of the film thickness tolerances of AS6450 will be permitted on contact (bearing) surfaces. The average thickness, based on six readings minimum, of the cured film of all Types shall be between 0.0003 inch (0.008 mm) and 0.0005 inch (0.013 mm). Film
39、thickness shall be controlled on both external and internal threads by the process and by fit-check, i.e., when installed on appropriate thread gage the coated threads shall permit three quarter turn of free rotation, threads shall not exceed AS8879 MMC (Maximum Material Condition) during gage check
40、. 3.2.4 Composition The dry lubricant shall be composed of molybdenum disulfide, in accordance with AMS-M-7866, combined with suitable bonding agents to meet the requirements of this document. The requirements of AMS-M-7866 for molybdenum disulfide particle size shall not apply. The material manufac
41、ture shall select a grade/particle size of molybdenum disulfide that is suitable for meeting all performance requirements and material characteristics of this specification, and shall not change grade/particle size for production lots from that which was qualified. Manufacturing processes shall also
42、 be controlled to ensure the final particle size of molybdenum disulfide contained within material production lots remains consistent with that of the materials submitted for qualification. The product shall not contain lead, chrome, mercury, cadmium, antimony, or their compounds. The dry lubricant
43、shall not contain any compounds that have a residual high vapor pressure after the cure cycle or are leachable by common industrial solvents. 3.2.5 Toxic Products, Formulations, and Health Hazard Evaluation The dry film lubricant shall have no known adverse effect on the health of personnel when use
44、d for intended purpose. The dry film lubricant shall contain no components which produce harmful vapors during or after installation. Health hazard evaluation shall be performed for each new material qualified to this specification in accordance with RE-ADD-030 to establish its usage precautions. A
45、Material Safety Data Sheet shall be submitted in accordance with 1.3. 3.3 Performance Requirements 3.3.1 Liquid Oxygen (LOX) and Gaseous Oxygen Compatibility (Type I Oxygen Components only) The supplier shall submit written evidence that the cured lubricant does not react in liquid or gaseous oxygen
