ASTM D3115 Test Method for Explosive Reactivity of Lubricants with Aerospace Alloys Under High Shear
4. Summary of Test Method
4.1 A shaped dowel pin made of the test material is rotated at 1760 rpm under a pressure of 689 MPa (1000 psi) for 1 min in a shaped hole (drilled into a block of the test material) containing the test lubricant. Observation for indications of reaction is made.
5. Significance and Use
5.1 Explosive reactivity has resulted when parts made from some light alloys, typically high in aluminum and magnesium, are loaded under shear conditions while in contact with certain lubricants. A typical example is a threaded part, lubricated with a chlorofluorocarbon grease, pulled up normally tight.
