10、fication for wrought steels43.Summary of Test Method3.1 This test method is divided into two parts:3.1.1 Part AUsed only for fluids where water is thecontinuous phase.Examples of such fluids include water-glycol hydraulic fluids and high-water-content hydraulic fluids.Do not use Part A to evaluate i
11、nvert emulsion hydraulic fluids.3.1.2 Part BUsed for both water-containing fluids andcompletely water-free fluids such as petroleum based hydraulicfluids,except phosphate esters.In Part B a small beaker ofwater is present to provide water vapor to cause corrosion inthe absence of a vapor-phase inhib
12、itor in the fluid.Part B is theappropriate procedure for evaluating invert emulsion hydraulicfluids.3.2 In both Part A and Part B,a steel specimen is attachedto the underside of the cover of a beaker containing the fluidunder test.The apparatus and specimen are identical to those ofTest Method D3603
13、.The fluid is brought to a test temperatureof 60 C(140 F).1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.N0 on Hydraulic Fluids.Current edition approved April 1,2018.Published June
