The lubricating oil furnished under this specifica
22、tion shall be products that are authorized by the qualifying activity for listing on the applicable qualified products list before contract award (see 4.2 and 6.3). 3.2 Materials. The composition of the lubricating oil is not limited; however, materials containing barium, organic compounds of titani
23、um, and known or suspected human carcinogens (as specified by the Occupational Safety and Health Standards Hazard Communications, 29 CFR 1910.1200) are prohibited. Recycled basestocks are permitted; however, each batch must be fully tested in accordance with the qualification requirements of this sp

The acid components, in mole-percent, of the finished oil submitted as the qualification test sample shall be determined in accor
25、dance with FED-STD-791, method 3500, “Monobasic Acid Components of Synthetic Ester Lubricants by Gas Chromatography.” The manufacturer shall then select a range of 10 mole-percent for each acid component to bracket the values measured on the qualification sample by the qualifying laboratory. The maj
26、or acid components (10 mole-percent or greater) of the oil shall fall within the stated range for each acid. The minor acid components shall not exceed 10 mole-percent. The manufacturer may use alternate methods to determine the acid components as described in Table I, footnote 1. 3.3 Chemical and p
