27、-7808L53. REQUIREMENTS3.1 Qualification. The lubricating oils furnished under this specification shall be products that are authorized bythe Qualifying Activity for listing on the applicable Qualified Products List (QPL) before contract award (see 4.2and 6.3).3.2 Materials. The composition of this l

28、ubricating oil is not limited; however, organometallic compounds oftitanium and silicone antifoam agents and known or suspected human carcinogens (as defined by the OccupationalSafety and Health Standards - Hazard Communications, 29 CFR 1910.1200) are prohibited. If the lubricating oilcontains a tri

29、cresyl phosphate additive, not more than 1 percent of the tricresyl phosphate additive shall be orthoisomer. The engine lubricating oil shall have no adverse effect on the health of personnel when used for itsintended purpose. Recycled basestocks are permitted; however, each batch must be fully test

30、ed in accordance withall qualification requirements of this specification. The manufacturer may be required to submit certification ofconformance to this paragraph (see 6.2).3.2.1 Ozone depleting chemicals.
