MIL-STD-419 Cleaning, Protecting, And Testing Piping, Tubing, And Fittings For Hydraulic Power Transmission EquipmentThis standard covers the requirements governing the basic methods of cleaning and protecting nonferrous and ferrous metal and alloyed pipe, tubing, and fittings prior to installation and after hydraulic tests in hydraulic power transmission applications. This standard is applicable to hydraulic components used in systems filled with either petroleum oil, synthetic poly-alpha-olephin PAO fluid, phosphate ester type fluid, or water based fluid.
