QPL MILPRF 87937 Performance Specification.pdf

This is a Performance Specification for biodegradable, water-dilutable cleaning compounds for aerospace equipment use by all Department of Defense departments and agencies.

The specification establishes requirements for three types of cleaning compounds: Type I (Terpene Based, Solvent Emulsion, Water Dilutable), Type III (Gel-Type), and Type IV (Heavy Duty, Water Dilutable). Type I compounds must contain 25-40% terpene hydrocarbons and achieve minimum 95% cleaning efficiency with flash points between 120-200°F. Type III gel compounds require minimum 65% cleaning efficiency with no terpene hydrocarbons, while Type IV heavy-duty formulations require minimum 90% cleaning efficiency and demonstrate no flash point up to their boiling point. All formulations must be biodegradable (75% minimum for Type I and Types III-IV at 85% minimum over 28 days), non-toxic to aquatic organisms per EPA methods, and contain no hazardous compounds per 40 CFR regulations. Products must undergo comprehensive qualification testing including immersion corrosion, hydrogen embrittlement, effects on painted and unpainted surfaces, stress crazing of acrylic and polycarbonate plastics, compatibility with rubber and polysulfide sealants, and 12-month storage stability. Qualification samples of 12 liters must be submitted with complete formulation data, safety data sheets, toxicological data, and biodegradability certifications. Conformance inspection includes sampling and testing from each production lot, with rejection of entire lots failing any requirement. The specification requires re-qualification every five years with 2.5-year recertification intervals. Products must be listed on the Qualified Products List (QPL) maintained by Air Force Petroleum Office (AFPET/PTPS) at Wright-Patterson AFB, Ohio before contract award.
